    Most common repairs needed to fix a KitchenAid dishwasher

    Drain Pump Replacement

    A dishwasher that won’t drain often has a failed drain pump. The drain pump motor could be bad or the drain pump impeller could be damaged. The drain pump may make a loud noise when the impeller is damaged. The motor may make a loud buzzing noise or not make any noise at all if it isn’t spinning the impeller during the drain portion of the dishwashing cycle. The drain pump is hard to access so you’ll need to have a Sears Home Services Technician check out the drain pump and replace it if it isn’t working.


    Pump and Motor Assembly Replacement

    When the dishwasher won't drain, the pump and motor assembly that drains the water is often faulty. The motor spins a pump impeller and the impeller that moves the water through the drain hose could be damaged. A faulty motor could also be failing to spin the impeller properly. You'll likely hear a grinding or whining noise when those failures are happening. Have a Sears Home Services Technician repair the dishwasher when a faulty pump isn’t draining the water properly.

    Drain Hose Replacement

    A dishwasher that won’t drain often has a failed drain pump. The drain pump motor could be bad or the drain pump impeller could be damaged. The drain pump may make a loud noise when the impeller is damaged. The motor may make a loud buzzing noise or not make any noise at all if it isn’t spinning the impeller during the drain portion of the dishwashing cycle. The drain pump is hard to access so you’ll need to have a Sears Home Services Technician check out the drain pump and replace it if it isn’t working.

    Sears Home Services recommendations for a dishwasher that won't drain

    When the dishwasher won't drain 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 won't drain 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.

    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.
