The right portable dishwasher hose is the one made for your dishwasher's brand and model. You need either a fill and drain assembly for the faucet side or a drain extension for the sink side.
We compared six hoses and kits on length, fit, material and what each maker says about them. Check your faucet first, then match the brand and model, before you buy anything.
Five of the six are fill and drain assemblies for portable or countertop dishwashers, and the HLMOptimo is a drain kit described for washing machines, so read that card closely. The countertop and portable dishwashers guide explains the wider setup if you're new to these parts.

The 6 best portable dishwasher hoses and extension kits in detail
The Magtonson 8-foot GE hose scores highest because it names a GE part number and includes a faucet adapter with a mesh filter. The HLMOptimo kit scores lowest because it's described for washing machine drains.
Magtonson 8 ft GE
- 8 ft fill and drain assembly
- Faucet adapter with mesh filter
- Extra rubber washer included
- One-year warranty
An 8-foot fill and drain hose for GE portables, with a faucet adapter that has a mesh filter.
Pros
- Matched to a named GE part number
- Faucet adapter with mesh filter and extra washer
- One-year warranty from Magtonson
Cons
- Magtonson names GE portable dishwashers only
- At 8 ft, it may not reach a faucet far from the unit
The Magtonson 8-foot hose is made for GE portable dishwashers, and its name carries the GE part number WD24X10066. If your dishwasher is a GE portable, that number is the first thing to match.
It's a fill and drain assembly, so one end connects to the faucet and the other to the dishwasher. The faucet adapter comes with a mesh filter and an extra rubber washer.
The adapter's inside thread is 55/64 inch by 27, and its outside thread is 15/16 inch by 27. Several adapters in the best faucet adapters for portable dishwashers roundup name the same sizes.
The hose is rubber. Magtonson calls it OEM quality and gives a one-year warranty.
Measure from your faucet to where the unit will sit, so you know whether 8 feet gives enough reach. Skip it if your dishwasher isn't a GE portable, since the part is matched to GE units.
Magtonson 6 ft GE
- 6 ft fill and drain assembly
- Faucet adapter with mesh filter
- Extra rubber washer included
- Part number WD24X10066 named
A 6-foot fill and drain hose for GE portables, with the same mesh-filter faucet adapter as the 8-foot version.
Pros
- Matched to a named GE part number
- Faucet adapter with mesh filter and extra washer
- One-year warranty from Magtonson
Cons
- Magtonson names GE portable dishwashers only
- At 6 ft, it is 2 ft shorter than the 8 ft GE hose
The Magtonson 6-foot hose is the shorter version of the GE hose, and its name carries the same GE part number, WD24X10066. Magtonson says it is compatible with GE portable dishwashers.
It's a fill and drain assembly, so one end goes to the faucet adapter and the other to the dishwasher. The adapter has a mesh filter and an extra rubber washer, with a 55/64 inch inside thread and a 15/16 inch outside thread.
The hose is rubber. Magtonson calls it OEM quality and gives a one-year warranty.
This is a replacement-style hose, so match it to your dishwasher's brand and model and read your manual before you order. Measure from your faucet to where the unit will sit, since 6 feet is 2 feet shorter than the 8-foot version.
Skip it if your dishwasher isn't a GE portable, or if your faucet is far from the unit.
Magtonson 6 ft Whirlpool
- 6 ft fill and drain assembly
- Same mesh-filter faucet adapter
- Compatible with W10273574
- One-year warranty
A 6-foot fill and drain hose for Whirlpool and Kenmore portables, with the same mesh-filter adapter as the GE model.
Pros
- Named Whirlpool and Kenmore fit
- Same faucet adapter with mesh filter
- One-year warranty from Magtonson
Cons
- Magtonson names Whirlpool and Kenmore models only
- 6 ft is shorter than the 8 ft options
The Magtonson 6-foot Whirlpool hose is made for Whirlpool and Kenmore portable dishwashers, and its name carries part W10273574. Match that number to the one on your old hose or in the manual.
It's a fill and drain assembly with a faucet adapter that has a mesh filter and an extra rubber washer. The adapter's threads are 55/64 inch inside and 15/16 inch outside, both at 27 threads per inch.
The hose is 6 feet long, which is shorter than the 8-foot GE hose. Measure the run first, since a short hose can't reach a far faucet.
If you have an older hose, compare its part number with W10273574 before you assume it fits. Magtonson calls the hose OEM quality and gives a one-year warranty.
Skip it if your dishwasher isn't a Whirlpool or Kenmore. The hose is built for those models.
Garsoo 8 ft Universal Kit
- 8 ft total
- Faucet adapter, inlet and outlet hoses
- Sealing tape included
- One-year manufacturer warranty
An 8-foot universal kit with a faucet adapter, inlet and outlet hoses and sealing tape in the box.
Pros
- Adapter, both hoses and tape in one kit
- Garsoo says it fits all major brands
- Gasket included to help prevent leaks, Garsoo says
Cons
- Brand fit is Garsoo's claim, so check the connector sizes
- Two connector sizes must match your unit
The Garsoo 8-foot kit has a faucet adapter, inlet and outlet hoses, and sealing tape in the box. Garsoo says it works with all major brands.
The faucet adapter has a 15/16 inch external thread and a 55/64 inch internal thread. The two hose connectors have internal threads of 61/64 inch and 23/32 inch.
Because the kit has two connector sizes, match them to your dishwasher's inlet and outlet. A kit that says all major brands still needs the sizes to line up.
Garsoo says the included gasket helps prevent leaks at the adapter, and the kit is made of polyoxymethylene plastic. Garsoo gives a one-year manufacturer warranty and says it replies to questions within 12 hours.
Skip it if you want a hose made for one brand and model, since this kit is written for all major brands.
Garsoo 6 ft Universal Kit
- 6 ft total
- Faucet adapter, inlet and outlet hoses
- Sealing tape included
- One-year manufacturer warranty
A 6-foot universal kit with a faucet adapter, inlet and outlet hoses and sealing tape in the box.
Pros
- Adapter, both hoses and tape in one kit
- Garsoo says it fits all major brands
- Gasket included to help prevent leaks, Garsoo says
Cons
- Brand fit is Garsoo's claim, so check the connector sizes
- At 6 ft, it may not reach a faucet far from the unit
The Garsoo 6-foot kit is the shorter version of the 8-foot kit, with a total length of 6 feet. It comes with a faucet adapter, inlet and outlet hoses, and sealing tape, and Garsoo says it works with all major brands.
The faucet adapter has a 15/16 inch external thread and a 55/64 inch internal thread. The large hose connector has a 61/64 inch internal thread, and the small one has a 23/32 inch internal thread.
This is a replacement-style kit, so match both connector sizes to your dishwasher's inlet and outlet and check them against your manual. A kit that says all major brands still needs the sizes to line up.
Garsoo says the included gasket helps prevent leaks at the adapter. It gives a one-year manufacturer warranty and says it replies to questions within 12 hours.
Skip it if your faucet or sink is far from the unit, or if you want a hose made for one brand and model.
HLMOptimo 10 ft Drain Kit
- Extension adapter included
- Clamps and a U-bend holder
- EVA hose
- Outlets from 3/4 to 1-1/2 in
A drain kit described for washing machine outlets, with an extension adapter, clamps and a U-bend holder.
Pros
- Extension adapter and clamps included
- U-bend holder in the box
- Four outlet sizes named
Cons
- HLMOptimo describes it as a washing machine drain hose
- Gives both 6 ft and 10 ft, so confirm the length
- Only fits the washer outlet sizes named
The HLMOptimo is a drain kit with a 6-foot hose, an extension adapter, clamps and a U-bend holder, and its name gives a 10-foot total. HLMOptimo describes it as a washing machine drain hose, even though the name says dishwasher.
It names outlet sizes of 3/4, 7/8, 1-1/4 and 1-1/2 inch. If your drain doesn't match one of those, this kit won't fit well.
The extension adapter joins two hoses, the clamps add strength at the joint, and the U-bend holder keeps the hose in place. The hose is EVA plastic with a 21 millimeter outside diameter.
HLMOptimo gives two clamps in some places and four in others, and both 6 feet and 10 feet for the length. Confirm the clamp count and the length with HLMOptimo before you rely on them.
Use the kit only if the outlet sizes match and your manual allows the extra length. Skip it if your dishwasher's drain fitting is a different size, or if you want a kit written for dishwashers.
Side by side: length, fit and material
Length and fit decide most of the choice here. The Magtonson and Garsoo products are fill and drain assemblies, while the HLMOptimo product is a drain part.
| Product | Best for | Length | Fits | Material | Our score |
|---|---|---|---|---|---|
| Magtonson 8 ft GE | a GE portable dishwasher | 8 ft | GE portable dishwashers (WD24X10066) | Rubber | 8.7 |
| Magtonson 6 ft GE | a GE portable near the faucet | 6 ft | GE portable dishwashers (WD24X10066) | Rubber | 8.5 |
| Magtonson 6 ft Whirlpool | a Kenmore or Whirlpool fill hose | 6 ft | Whirlpool and Kenmore portables (W10273574) | Rubber | 8.3 |
| Garsoo 8 ft Universal Kit | a universal fill and drain kit | 8 ft | Garsoo says all major brands | Polyoxymethylene plastic | 8.2 |
| Garsoo 6 ft Universal Kit | a short kit with sealing tape | 6 ft | Garsoo says all major brands | Polyoxymethylene plastic | 8.0 |
| HLMOptimo 10 ft Drain Kit | a washer-size drain outlet | 6 ft hose, 10 ft kit | Washer outlets of 3/4, 7/8, 1-1/4 or 1-1/2 in | EVA plastic | 7.0 |
The Magtonson hoses are rubber, and the Garsoo kits are polyoxymethylene plastic. The HLMOptimo kit is EVA plastic and described for washer outlets.
How we picked these six hoses
We compared the fit first, since a hose that doesn't match your brand or outlet can't do its job. Next we looked at length, material and what each maker says about its warranty.
Our score weighs specs, features and buyer feedback against what you're shopping for.
Named brand and model fits scored higher than an all-brands claim. Within each brand, the 8-foot hose scored a little higher than the 6-foot one for its extra reach.
The HLMOptimo kit scored lowest because it's described for washing machine outlets and doesn't replace a fill hose.
Fill and drain hoses or drain extensions: which do you need
A fill and drain hose connects the faucet to the dishwasher and carries waste water out. Those are the Magtonson and Garsoo products in this roundup.
A drain extension makes an existing drain hose longer. The HLMOptimo kit is a drain part, so it won't bring water to the unit.
Check which one you need before you buy. Many people need a fill hose and a drain hose, and a single kit may cover both.
Connector sizes: why they matter
A hose connector and an adapter have to match in thread and size, or the connection won't seal. Every faucet adapter here uses 15/16 inch and 55/64 inch threads, but the Garsoo kits also use 61/64 inch and 23/32 inch hose connectors.
The thread number, such as the 27 in 15/16-27, tells you how many threads sit in an inch. A different count is a different thread, even when the size looks the same.
Compare the connector sizes on your dishwasher with the numbers on each card. If a connector is a close size but not the same, pick a part with the exact size instead of forcing it.
Kit or single part: which saves time
The Garsoo kits put the faucet adapter and both hoses in one box, so you have fewer parts to match. That helps when you're not sure which piece you need.
The Magtonson assemblies come matched to a brand and include a faucet adapter. They save time if you already know your brand and model.
Either way, the faucet adapter has to suit your aerator, and the hose has to suit your dishwasher. Kits can include pieces you don't need, so read what's in the box.
Check your faucet first on the fill end
Check your faucet first. The aerator type, its thread and whether you have a pull-down or spray faucet all decide the fill end you need.
The will a portable dishwasher fit your faucet guide covers those checks, and how to hook up a portable dishwasher to your faucet walks through the connection.
Match the adapter thread to the hose
The faucet adapter on a fill hose has its own thread sizes. Compare those numbers with your aerator.
The Magtonson GE and Whirlpool hoses all use 55/64 inch inside and 15/16 inch outside threads. The Garsoo adapters use 15/16 inch external and 55/64 inch internal threads, and their hose connectors use different sizes.
For the adapter itself, see best faucet adapters for portable dishwashers.
Length: measure the run first
Measure the distance from the faucet to where the unit will sit, and add a little for bends. A hose that's too short can't reach the faucet, and extra length can kink if it's coiled tightly.
How long a portable dishwasher hose should be
Use the length your manual allows, and don't stretch a short hose to reach a far faucet or drain. The fill and drain hoses here are 6 or 8 feet, so pick the length closest to your run.
Coil any extra hose loosely, and keep it away from a sharp bend. A kink can slow the water or drain, so look over the hose after you move the unit.
Add up the whole path
Count both sides of the unit, not just one. The fill hose runs from the faucet to the dishwasher, and the drain hose runs from the dishwasher to the sink or drain.
A longer drain hose doesn't help if the fill hose can't reach the faucet. Sketch the layout, measure each leg, and compare the totals with the lengths in your manual.
Drain outlet sizes and fit
The drain outlet is the opening the hose connects to, and only the HLMOptimo card names outlet sizes. It names washer outlets of 3/4, 7/8, 1-1/4 or 1-1/2 inch.
The Magtonson hoses come matched to a named brand and part number, so the part number does the matching. Garsoo gives a large connector of 61/64 inch and a small connector of 23/32 inch, both internal threads.
Measure the outlet and compare it with those sizes. If none matches, don't force a hose on.
Maximum length and height
Your manual sets the maximum drain length and height. Check it before you connect a longer hose or any drain extension.
Those limits are the dishwasher maker's figures for your unit, so treat the manual as the last word on how far and how high the drain hose can run.
A longer drain hose can make draining slower. If your dishwasher drains slowly after you add a longer hose, read portable dishwasher not draining? easy fixes to try.
Materials, kinks and wear
Rubber hoses are flexible and common for fill and drain assemblies. The Magtonson hoses are rubber, so check the outer surface for cracks from time to time.
The Garsoo kits are polyoxymethylene plastic, and Garsoo describes the adapter head as metal with strong corrosion resistance. Check the adapter and its gasket whenever you move the unit.
EVA is a flexible plastic used in the HLMOptimo kit, and HLMOptimo calls the hose ultra-flexible and pressure resistant.
Store spare hoses out of direct sun and away from heat, so the material stays flexible. Replace a hose that cracks, swells or stays kinked after you straighten it.
What a drain extension does and does not fit
A drain extension makes a drain hose longer, and it doesn't bring water to the unit. The HLMOptimo kit joins two hoses with an extension adapter, and it's described for washing machine outlets, not dishwashers.
Many portables drain through their own hose into the sink, so follow your portable's manual for how that hose connects. Ask a licensed plumber to make any change to the drain.
Don't cut or reroute a drain line on your own. If you're not sure what your drain setup needs before you add an extension, ask a licensed plumber.
Warranty and support
Magtonson gives a one-year warranty on its GE and Whirlpool hoses, and Garsoo gives one year from the manufacturer on both kits. HLMOptimo gives no warranty term, so ask the maker about coverage.
Garsoo says it replies to questions within 12 hours. Keep the receipt and the model number with the hose, since a warranty claim usually needs both.
Renters: what to check before you change a hose
Check your lease before you change a hose or add a drain part. Some landlords want to approve any change to the plumbing, even one that comes off easily.
Keep the original hose. If you replace it, store the old one so you can put it back when you move out.
Take a photo of the connection before you change anything. A photo helps if the landlord asks what you connected.
If you're thinking about a permanent setup, read can you install a portable dishwasher permanently first. Any permanent change needs a licensed plumber.
Leaks and kinks: what to check
A worn, kinked or loose hose can leak. Look at the hose, the clamps and the fittings after you move the unit.
Unplug the dishwasher before you check any hose or fitting, and follow your manual for the washers and clamps. Don't use tape or sealant unless the manual says so.
If a leak keeps coming back, contact the maker or a repair pro instead of trying repeated fixes. If a part fails early, check the Consumer Product Safety Commission for recall notices before you buy a replacement.
Who should skip a drain extension
Skip a drain extension if your drain is far from the unit and you can't measure a safe run. A long, sagging hose can drain poorly, so a different setup may suit you better.
Skip it if your outlet size doesn't match the named sizes. A forced fit is more likely to leak than a correct one.
Skip it if your manual sets a shorter maximum than the extension you want. The manual wins.
Five checks before you buy a hose
Work through these checks first, since a mismatched hose is the simplest thing to avoid.
Confirm your dishwasher brand and model, and find the model number on the label. Match the hose to that number, not to the brand name alone.
Measure the run from the faucet to the unit, then from the unit to the drain outlet. Compare both measurements with the hose length.
Match the fill end to your faucet aerator, and the drain end to your outlet size. Check your manual's maximum length and height before you buy any extension.
Which portable dishwasher hose fits your setup
Pick the Magtonson 8-foot GE hose if your dishwasher is a GE portable and the faucet is some distance away. Pick the 6-foot GE hose if the faucet is close, or the Whirlpool hose if your unit is a Whirlpool or Kenmore model.
Pick a Garsoo kit if you want the adapter, both hoses and sealing tape in one box and your connectors match the unit. Choose the 8-foot kit for more reach and the 6-foot kit for a short run.
Pick the HLMOptimo kit only if your drain matches its washer outlet sizes and your manual allows the extra length.
Check your faucet first, match the fill hose to your brand and model, and follow the manual for each connection.

Frequently asked questions
Which dishwasher hose fits my model?
Start with your dishwasher's brand and model number, and match it to the hose's stated fit. Magtonson names GE and Whirlpool or Kenmore models, while Garsoo says its kits work with all major brands, so confirm the fit with your manual too.
How long should a portable dishwasher drain hose be?
Use the length your manual allows, since a longer drain hose can make draining slower. The fill and drain hoses here are 6 or 8 feet, so measure the run from the unit to the sink and check the manual's maximum length and height.
What connector sizes do these hoses use?
The Magtonson and Garsoo faucet adapters share two sizes: a 55/64 inch inside thread and a 15/16 inch outside thread. Garsoo's hose connectors add 61/64 and 23/32 inch internal threads, so match each size to your dishwasher's inlet and outlet and to your manual.
Can a dishwasher hose leak?
A worn, kinked or loose hose can leak, so unplug the dishwasher before you look at the hose, washers and clamps as your manual describes. If the leak keeps coming back, contact the maker or a repair pro instead of adding tape or sealant.
