Common dishwasher repair parts you may need

Replacing one of these dishwasher parts may fix your problem.

Pump and Motor Assembly Replacement

When your dishwasher is leaking, it might have a problem with the pump and motor assembly. A faulty water seal or a crack in the pump housing could be causing water to leak from the bottom of the dishwasher. It's important to address a leak promptly to avoid damaging your kitchen flooring and counters. Arrange for a Sears Home Services Repair Technician to come to your home and inspect your dishwasher. If the pump and motor assembly is found to be the source of the leak, the technician will replace it.

Electronic Control Board Replacement

If your dishwasher is leaking, it might have a problem with the control board. This board sends electrical current to the water fill valve to fill the dishwasher. If the electronic control board doesn't properly stop the flow of current to the fill valve, the dishwasher could overfill and start leaking. If you notice your dishwasher leaking, arrange for a Sears Home Services Repair Expert to come to your home and identify the source of the leak. If the control board is found to be defective, the technician will replace it.

Door Seal Replacement

When you discover your dishwasher is leaking, you might suspect that a worn or damaged door seal is to blame. The rubber gasket that encircles the tub opening is meant to prevent water from leaking out of the dishwasher when the door is closed. However, if the seal is worn or damaged, water can seep through the edges of the door. If you detect a leak in your dishwasher, it's advisable to have a Sears Home Services Technician come to your home and replace the door seal if it's found to be leaking.

What to expect when you experience a dishwasher leaking issue

How to repair the leaking problem

Fixing most leaks typically requires replacing either the pump and motor assembly, electronic control board, or door seal. However, since there are many potential causes, conducting a thorough diagnosis is crucial for fixing the problem. Getting an accurate diagnosis is important for understanding the cost of the repair.

Sears Home Services provides this advice for a dishwasher that is leaking

If your dishwasher is leaking, there could be several reasons why. To avoid replacing parts that might not be necessary, we suggest having a Sears Home Services professional conduct diagnostic tests to determine the main cause of the issue. Our technicians have extensive experience in diagnosing various types of dishwasher problems.

How to deal with a dishwasher leaking diagnosis

Figuring out problems with modern appliances can be hard if you don't have the right knowledge and training. If you don't use the right techniques to diagnose issues, you might end up just guessing and replacing parts randomly. Appliances, especially those made in the last 10 years, have gotten very advanced, with lots of electronic parts that are tricky to check. Doing repairs yourself on the latest appliance models is getting harder and harder.

Dishwasher leaks can come from a misaligned door seal, cracked hoses, or worn pump gaskets. Pooling water damages floors and cabinets. For a quick seal, use dishwasher service.

Thorough

James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
