A portable dishwasher fits your faucet when the adapter's thread matches the faucet's aerator and the hose end fits the dishwasher. Check both before you buy anything.

The portable dishwasher adapter sizes in this guide are 15/16-27 male and 55/64-27 female, so start there. Guessing the thread is the easiest mistake to make, so measure it instead.

Check your faucet first. Look at the aerator, the thread and whether the faucet pulls down or has a spray head, since each one changes the answer.

This guide covers faucet types, thread sizes, the hose end on the dishwasher and the adapters that come in the box. Tank models come up for faucets that won't take an adapter at all.

For the full range of models, see the countertop and portable dishwashers guide.

Check the faucet type before you buy an adapter

Start with the faucet type, since a removable aerator, a pull-down head and a faucet with no removable aerator each need a different plan. Most of the adapters here are made for faucets with a removable aerator.

Faucets with a removable aerator

The aerator is the small screen at the tip of the spout. If it unscrews, the faucet has a removable aerator, and that is the type most adapters in this guide are made for.

You can usually spot one by eye before you touch anything. Adapter kits ask you to remove the aerator first, so follow the steps that come with yours.

The iFealClear kit includes four aerator removal tools and says to take the aerator out before its adapter is used.

Pull-down and spray faucets

Pull-down and spray heads often need a different connection, so don't assume a standard adapter will fit. A pull-down head is the spout that stretches out on a hose from the faucet body.

iFealClear says its 18-piece kit doesn't work with pull-down faucets or with faucets that have non-removable aerators.

If your faucet pulls down, check each adapter's compatibility notes or choose a tank model instead. If an adapter's notes don't mention pull-down use, treat that as a no until the maker confirms otherwise.

Side sprays

A side spray is a separate hose beside the main spout. An adapter made for the main spout usually isn't the right part for it, so the kit's notes or the faucet maker's manual decide what fits.

Don't force a side spray onto an adapter made for another connection. If the fit is unclear, ask the maker before you order.

Faucets with no removable aerator

If the aerator is built into the spout, the iFealClear kit says it won't work with that faucet. Other adapters may need a different plan, so check their notes before you order.

A tank model avoids the question. Water tank vs faucet hookup countertop dishwashers compares the two routes side by side.

Read your aerator before you buy

Look at the aerator or the spout tip, then match what you see to the sizes in this guide. Work through these steps in order, and stop if the first one fails.

1. Confirm the aerator comes off. If the screen tip doesn't unscrew, an adapter made for removable aerators won't help, so plan on a tank model.
2. Note which way the threads run. Threads on the outside are male, and threads on the inside are female.
3. Measure the diameter. iFealClear advises measuring the faucet thread before you buy.
4. Compare the size with 15/16-27 or 55/64-27. A match at this step means one of the adapters here may fit.
5. Check the hose end on the dishwasher. The faucet side alone doesn't decide the fit.

If you need to take the aerator off, follow the kit's own steps. Don't use force on a stuck part, and stop if it won't come free.

Portable dishwasher adapter sizes: 15/16-27 male and 55/64-27 female

The two sizes are 15/16-27 male and 55/64-27 female. The first number is the diameter in inches, and the 27 is the number of threads per inch.

Male and female threads, explained

A male thread sits on the outside of a part, and a female thread sits on the inside. Mating threads are opposite types, so a male thread needs a female partner.

Match the type first, then check the size. An adapter can have the right size and still fail if the thread runs the wrong way.

If you can't tell which type your faucet has, measure the thread and read the kit's notes. A kit that carries both types gives you more options.

A worked example with both thread types

Say your spout has threads on the outside that measure 55/64-27. You need a female 55/64-27 thread to screw onto it.

Now say your spout has threads on the inside that measure 15/16-27. You need a male 15/16-27 thread to screw into it.

The Danco coupling and the Hygie Rinse set both carry those two threads. Neither helps if your measurement comes out to some other size, so measure before you choose.

Danco and Hygie Rinse portable dishwasher adapter sizes

Danco's 10507 is a chrome-plated brass snap coupling with 15/16-27 male and 55/64-27 female threads. Danco says the dual thread fits most regular-size faucets, and it rates the flow at 1.5 gallons per minute.

Hygie Rinse's snap-on set has a 55/64-27 female thread on the faucet side and includes a 15/16-27 male adapter for wider use. The bottom end is the dishwasher side, so check it against your hose.

Hygie Rinse says the rubber washers and snap-on design install without tools.

The iFealClear kit covers more sizes, but not dishwasher hookups

The iFealClear kit includes both 15/16-27 and 55/64-27 threads, male and female, along with other sizes for garden hoses. iFealClear says it isn't compatible with dishwashers or pull-down faucets, so read its notes before you use it.

iFealClear advises measuring the faucet thread before you buy, so measure it rather than trusting a photo. It points the kit at bathroom faucets with removable aerators, garden hoses and RVs, which are the jobs to match it to.

Check the hose end on your dishwasher

The hose end on your dishwasher has to match the adapter's connection end, so check the inner diameter of both before you order. A matching thread on the faucet doesn't help if the hose end is the wrong size.

Piumeif tells buyers to check the inner diameter of the adapter's interface end against the dishwasher hose. It makes the adapter as an aftermarket part and names Danby, LG, SPT, Panda and Rovsun only to show compatibility.

Piumeif describes its thread only as dual-threaded and gives no size, so measure your faucet before you rely on this adapter. For hose options, best portable dishwasher hoses and extension kits compares the choices.

Measure the hose end on your dishwasher

Measure the inside of the hose end with a ruler or caliper, and write the number down. Then compare it with the connection end of the adapter, using the figure the maker gives.

A guess at this number is a common reason a fit fails. Hose ends come in more than one size, so trust the measured inner diameter and not the hose's appearance.

When the two ends don't match

If the hose end and the adapter don't match, don't force the fit. Look for an adapter that matches both ends, or ask the maker which parts work together.

A part that needs force is usually the wrong part. Stop, check the sizes again and compare them with your measurements.

Check the adapter that comes in the box

Some dishwashers include an adapter, and that included part still has to match your faucet. Check its thread and its hose end the same way you would for any other adapter.

COMFEE' says its 6-place model connects to a faucet with a suitable adapter, and a faucet adapter and quick connect come in the box. BLACK+DECKER includes an adapter with its Quick Connect assembly.

The COMFEE' mini comes with a faucet hose and adapter, and it can run from its built-in tank instead.

The only box contents named for the Hamilton Beach are the dishwasher and its racks. Check for an adapter before you plan to connect it to a faucet.

Whatever comes in the box, confirm that its thread fits your faucet before you connect anything. If an included adapter looks worn or loose, don't use it, and ask the maker for a replacement.

Five checks before you buy an adapter

Run these five checks in order, so you buy an adapter that matches both ends. Checks two and three set the size, so give them the most time.

1. Faucet type: removable aerator, pull-down, spray or none.
2. Faucet thread: 15/16-27 male, 55/64-27 female, or another size.
3. Dishwasher hose end: the inner diameter of the connection.
4. Included adapter: does the one in the box match checks 2 and 3?
5. Kit notes: any named exclusions, such as pull-down faucets.

If any check fails, that adapter is the wrong part for your setup. Ask the maker before you order, or choose a tank model.

Write down each answer as you go, so you can compare it with the kit when it arrives.

Questions to ask the maker before you order

Ask the maker three things before you order: which faucet threads the adapter fits, which hose ends it connects to, and whether it works with pull-down or non-removable aerator faucets. A clear answer to each is worth more than a long product description.

If the maker can't answer these, pick a different adapter or a tank model.

Keep the original aerator if you rent

If the sink isn't yours, ask your landlord before you take the aerator off. Then keep the original aerator and its washers in a labeled bag.

Put the faucet back as you found it when the dishwasher is out of use or when you move. Hygie Rinse's set works as a plain aerator when no dishwasher is connected, which is one way to leave the spout in working order.

Three fit mistakes to avoid

Three mistakes are easy to make: matching the photo instead of the faucet, skipping the hose end and assuming one kit works for every job. Each one is simple to avoid when you check before you buy.

Matching the photo instead of the faucet

A photo of the adapter shows its shape, not the thread on your faucet. Measure your own faucet, then choose the adapter that matches those numbers.

Skipping the hose end

A good fit at the faucet doesn't help if the dishwasher end is the wrong size. Piumeif's advice to check the inner diameter applies to any adapter you buy.

Assuming one kit works for every job

Garden hose kits and dishwasher adapters are different jobs, even when they share a thread size. iFealClear's kit covers garden hoses and removable aerators, and iFealClear says it isn't for dishwashers.

What to do if the connection drips or leaks

Turn off the faucet and unplug the dishwasher before you check anything. Then follow the manual's connection steps, and if the drip continues, contact the maker or a repair pro.

Keep the manual open while you connect anything, and follow its order rather than a guess. If the manual's order differs from this guide, the manual wins, since it knows your exact parts and model.

Anything that changes your plumbing is a job for a licensed plumber, not a home fix.

How to hook up a portable dishwasher to your faucet covers the normal hookup steps and the points where the manual matters most. The Consumer Product Safety Commission takes reports on home products that cause injury or a hazard.

Use a tank model when the faucet won't work

A tank model skips the faucet, so it's the simpler choice when your faucet has no removable aerator or the adapter won't match. It removes the thread question entirely.

COMFEE' says its mini runs from a 1.32-gallon built-in tank that you fill by hand, so it doesn't need an adapter to work. The countertop dishwasher with no plumbing guide explains that route in more detail.

A tank route trades the thread question for a different chore. You still need an outlet, you fill the tank by hand, and the waste water needs somewhere to go.

If the unit has to sit under the sink, can you put a countertop dishwasher under the sink answers the space question first. If you're still picking a model, how to choose a portable dishwasher for an apartment covers the other choices.

Choose the portable dishwasher adapter that matches your faucet

Pick a snap-on or dual-thread adapter when your faucet has a removable aerator that matches 15/16-27 male or 55/64-27 female threads, and the hose end matches too. Confirm both ends before you order.

• Pick the Danco coupling if your faucet matches one of its two threads and you want a single piece.
• Pick the Hygie Rinse set if you want both thread types and a plain aerator for when the dishwasher isn't connected.
• Pick the Piumeif adapter if your dishwasher is one of the brands it names and you have checked the hose end.
• Pick the iFealClear kit for garden hose or aerator jobs, not for a dishwasher hookup.
• Pick a tank model if your faucet has no removable aerator, or if you can't confirm a fit.

Frequently asked questions

How do I know if my faucet will take a portable dishwasher adapter?

Check whether the aerator unscrews, then measure its thread and compare it with 15/16-27 male or 55/64-27 female. Also check the hose end on your dishwasher, since the adapter has to fit both ends of the connection before the hookup will work.

What thread sizes do these adapters use?

Danco and Hygie Rinse use 15/16-27 male and 55/64-27 female threads, while the iFealClear kit carries both sizes plus garden hose sizes. The iFealClear kit is built for garden hoses and removable aerators, not dishwasher hookups, so read the notes on any kit before you order.

Will a portable dishwasher work with a pull-down faucet?

Not always, because iFealClear says its kit doesn't work with pull-down faucets, and other adapters may need a different connection. Check each adapter's compatibility notes and your dishwasher's manual first, or choose a tank model that doesn't need a faucet at all.

What should I do if the connection leaks?

Turn off the faucet and unplug the dishwasher before you check anything, then follow the manual's connection steps. If the drip continues, contact the maker or a repair pro, and ask a licensed plumber about any change to your plumbing.
