How to Repair Your Dishwasher: 3 Repairs You Can Handle Yourself
A dishwasher is a true time-saver. With this must-have appliance, you reduce the time you spend scrubbing your plates while keeping your sink clear of dirty dishes. When your dishwasher is not working properly, you'll want it fixed quickly. But before you reach for the phone to call us, hang on! Here are three dishwasher repairs you can easily do yourself to save you some money.
Common Dishwasher Problems You Can Fix Yourself
Now, don't get us wrong: some dishwasher repairs require a professional touch. If your dishwasher isn’t working, though, you should check these problems first:
- Is it clogged?
- Is there a problem with the water heater?
- Are there leaks I can fix myself?
Repair #1: Unclogging Your Dishwasher
Repairing a dishwasher is often as easy as removing a clog (here are Five Signs of a Clogged Dishwasher). Take the following steps:
- Disconnect the dishwasher from its power source to prevent electrical shock.
- Remove any standing water.
- Locate the dishwasher filter and remove it (the filter is at the bottom of the tub on most models).
- Clean the filter under running water or with a soft brush, then replace it.
If that doesn't work, there may be a clog in the drain hose:
- Locate the drain hose (it’s usually behind the dishwasher or in the sink cabinet).
- Disconnect the hose and inspect it for blockages. You can take the hose outside and use the garden hose to clear it.
- Replace the hose.
Some dishwashers drain through garbage disposals. If this is the case, run the disposal to clear any debris.
You can also add a mixture of equal parts baking soda and vinegar to the bottom of the dishwasher, let it foam up, and sit for 20 minutes. Then, flush it out with hot water and run the rinse cycle. Doing so will hopefully unclog the machine.

Repair #2: Checking the Water Heater
If you notice that your dishes aren't coming out clean, it may not be your dishwasher at all. If the water from your plumbing system isn't hot enough, your plates will never fully be sanitized. Are your showers lukewarm, too? A dishwasher repair may not be necessary at all. Adjusting the thermostat of your water heater ensures that all your appliances receive warmer water. If this doesn’t work, you may have a problem with your water heater.
Repair #3: Fixing Leaks Around the Dishwasher Door
If your dishwasher is leaking around the door, check the door gasket:
- Examine the gasket for damage, cracks, or tears. A damaged gasket should be replaced.
- Clean any dirt or debris off the gasket for a better seal.
- Verify that the gasket is aligned correctly.
- Check the level of the dishwasher. An incorrectly labeled dishwasher can leak.
Problems with the door latch or hinges can also cause leaks. Try the following fixes:
- Check the latches for signs of damage.
- Tighten loose hinges or the latch with a screwdriver.
- Check the screws holding the door in place to ensure they’re secure.
Additional DIY Checks to Try When Repairing Your Dishwasher
If dishes aren’t getting clean enough, try cleaning the spray arm:
- Check that the spray arm is spinning correctly.
- Remove any food particles or debris from the arm.
- Twist off the spray-arm cap (it should pop off when turned clockwise) and remove any excess debris you see.
