    Most common repairs needed to fix a KitchenAid dishwasher

    Pump and Motor Assembly Replacement

    When a dishwasher is leaking from the bottom, it could have a faulty pump and motor assembly. A bad water seal or crack in the pump housing could be causing water to leak out of the bottom of the dishwasher. As soon as you see a leak, you’ll need to act quickly to prevent damage to kitchen flooring and counters. Schedule a Sears Home Services Repair Technician to visit your home and examine your dishwasher. The technician will replace the pump and motor assembly if it’s the source of the leak.


    Water Valve Replacement

    A fill valve clogged with debris or deposits can fail to shut properly, causing the dishwasher to overfill and leak water. You may see the dishwasher fill with water in between cycles even when it’s completely off when debris or deposits prevent the water valve from closing completely. Shut off the water supply to the dishwasher and have a Sears Home Services Repair Expert fix your dishwasher if the dishwasher leaks water and clogged water valve isn’t shutting off water properly.

    Drain Hose Replacement

    When a dishwasher is leaking from the bottom, it could have a faulty pump and motor assembly. A bad water seal or crack in the pump housing could be causing water to leak out of the bottom of the dishwasher. As soon as you see a leak, you’ll need to act quickly to prevent damage to kitchen flooring and counters. Schedule a Sears Home Services Repair Technician to visit your home and examine your dishwasher. The technician will replace the pump and motor assembly if it’s the source of the leak.

    What to expect when you experience a KitchenAid dishwasher leaking from bottom issue

    How is the leaking from bottom problem fixed?

    Correcting most leaking from bottom problems usually involves replacing the pump and motor assembly, water valve or drain hose. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    Sears Home Services recommendations for a dishwasher that is leaking from bottom

    When the dishwasher is leaking from bottom it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

    What to look out for with a dishwasher leaking from bottom diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

    Troubleshooting a Kitchen Aid Dishwasher Leaking from the Bottom

    Leaks from the bottom of a Kitchen Aid dishwasher often come from the water seal around the pump and motor assembly. The seal surrounding the circulation pump wears out over time and starts leaking. Having a Sears Home Services technician replace that pump and motor assembly seal often fixes a Kitchen Aid dishwasher leaking from the bottom.

    Another common cause of a Kitchen Aid dishwasher leaking from the bottom is a leak through the diverter assembly. The diverter assembly routes spray water through the upper spray arm assembly during the washer cycle. A water seal in that device can develop a leak at the bottom of the dishwasher.

    Water can also leak through the water seals around the heating element mounting nuts. Replacing the heating element will typically fix that type of leak. The new heating element will include new water seals.

    Several other components such as the drain pump, overfill float stand pipe or the water supply line connection can also cause your Kitchen Aid dishwasher to leak from the bottom. When you can’t find and fix a dishwasher leak on your own, schedule dishwasher repair service to have a Sears Home Services technician fix the problem.

    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.
