How to fix and replace your Dishwasher Water Inlet Valve?

The water inlet valve is responsible for all the clean water used by your dishwasher to wash and scrub squeaky clean your dishware. Without this source, your dishwasher won’t be able to perform at its best, or wash dishes at all. It’s important to keep the dishwasher water inlet valve functioning.

If you encounter that the dishwasher often leaves a soapy mess on your dishware, there might be something wrong with either the dishwasher’s parts that make up for cleaning or there’s something wrong with the inlet valve that lets the water shoot from the dishwasher’s water jets.

There’s only one way to find out; you need to troubleshoot your dishwasher first and find out if the problem lies with the water inlet valve. You’ll know this if the dishwasher doesn’t fill with water and it doesn’t rinse properly. When you have concluded that it’s really the dishwasher inlet valve, you’ll have to fix it following the guide in this article.

 

How to test if a dishwasher water inlet valve is working?

The water inlet valve is controlled by one or two solenoids. If the water valve isn’t working the cause may be the solenoids have failed. You can test the valve by hooking up the ohmmeter to the terminals. A reading of infinity indicates that the solenoid has stopped functioning.

If the solenoid works but the valve is still not working, test the seal found in the valve. If it’s broken, you need to replace it. Also check the hoses connected to the inlet valve as this may be clogged by dirt build-up or food debris. Check both water supply and drain hoses just to be sure.

 

What is the step-by-step procedure for fixing and replacing the dishwasher water inlet valve?

The dishwasher water inlet valve is not that hard to fix and replace, especially if you have prior experience to troubleshooting your dishwasher. Hiring a person, a plumber for instance, to fix your dishwasher water inlet valve may be costly and you’re better off using that money to purchase parts replacement, if ever.

If you have yet to see a valve, a good example is the:

 

GE Dishwasher Water Inlet Valve WD15X10003

WD15X10003 for GE Dishwasher Water Solenoid Inlet Valve PS259368 AP2039343
  • Replacement General Electric part number WD15X10003.
  • This is a Dishwasher Water Inlet Valve Assembly with bracket and solenoid.
  • It has a 3/8" female pipe inlet.

 

Step 1: Shut off the water and power connections of your dishwasher. This is to keep you safe while you are tinkering with your appliance. Water and electricity aren’t a good combination.

Step 2: Move out your dishwasher from its safe haven (if it is in-built) and place it on a pedestal so you can easily see the bottom parts. You will need to remove the screws holding the bottom cover in place. Also unscrew the ones holding the dishwasher door to easily locate the inlet valve.

Remember, not all locations of the inlet valve are the same for all dishwashers. If you can, study the manual that comes with the dishwasher so you can easily pinpoint the location of the parts. If you don’t have a manual, check online to see the exact parts of the model.

Step 3: Locate the inlet valve. Once you have found this, detach the water hose from the valve and thoroughly remove the valve from the dishwasher by unscrewing the bolts that hold it. Also remove the electrical harness attached to the valve’s assembly.

Step 4: Have a rag ready when you remove the hose from the valve as extra water might pour out. Check the valve if it’s the reason why water won’t come inside the dishwasher anymore. Sometimes a clog in the hose may just cause it. If you find that it is unobstructed, the valve itself may be the culprit.

Step 5: You may need to replace your valve if this is the case. Depending on your model, you might not be able to purchase a generic one. Get something that is manufactured by the same company that made your dishwasher. For instance, LG Electronics owners may buy this replacement:

  • LG Electronics part number 5221DD1001A
  • Dishwasher water inlet valve
  • See product description for a full list of compatible models

 

Some replacement valve kits come with new hoses and fittings. If you can still use the fittings and hoses you previously use, then keep using that and store the new ones you got for backup.

Step 6: Attach the fittings onto the dishwasher. Place the new valve securely in the fittings as well as the hose connecting to the water supply. Don’t forget to remove old tapes fitted into the valve and replace it with new Teflon tape. Use a clamp to hold all the parts together. This keeps the outlet hose properly sealed and prevents any leakage.

Step 7: Turn on the electricity and the water supply and do an empty run on the dishwasher to see if water is freely running inside again. Watch closely if there are any leaks in the newly installed valve as well as the hoses. If it seems like everything is working in tip-top shape, put back all the covers of the dishwasher that you have previously removed.

If you find that something is still wrong with the dishwasher even if the valve is correctly installed, you might need the help of a repairperson, or call the manufacturer so they can send help, especially if it’s still under warranty.

Key Takeaway: One person who has experience with regards to doing DIY projects around the house may do this procedure. If trying this for the first time, ask someone help you so you may not be confused with all the parts and the fittings.

It is relatively easy to install a valve because it’s a single piece only, such as:

Conclusion

The dishwasher water inlet valve is a very important part of the dishwasher because it is the one responsible for filling the dishwasher with the right amount of water. It is able to fill up the washer at a certain point, and stop according to the chosen wash cycle. Because of the heaviness of its job, it’s only normal that it would need replacement at some point. The great thing is that water inlet valves are rather inexpensive and relatively easy to repair or replace.
