    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.

    Most common repairs needed to fix a Whirlpool dishwasher

    Filter Replacement

    A blocked filter in the dishwasher pump could be the reason your dishwasher drain is clogged. The pump filter is responsible for trapping food particles and debris, preventing them from entering the drain pump and causing a blockage. When this filter becomes clogged, water can't flow freely through the system, leading to drainage issues. You might notice water pooling at the bottom of your dishwasher or slow draining as a result. To resolve this, check the pump filter for any debris and clean it thoroughly. If the problem persists, schedule an in-home repair appointment through Sears Home Services to have a technician inspect the pump filter to ensure your dishwasher drains properly.

    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.

    Drain Hose Replacement

    When the dishwasher will not drain properly, a cracked or clogged drain hose could be causing the failure. The drain hose connects to the drain pump and carries wastewater to the sink drain. The drain hose has a check valve to prevent drain water from siphoning back into the dishwasher at the end of the drain routine. A cracked hose or check valve can let water blow back into the tub when the drain pump stops. Accessing the drain hose is difficult so you'll need to have a Sears Home Services Repair Expert fix the drain hose when it's cracked or damaged.

    How is the dishwasher drain clogged issue fixed?

    Correcting most dishwasher drain clogged issues involves replacing the filter, drain pump 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 drain clogged problem

    When a dishwasher drain is clogged, 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 drain clogged 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.
