Common dishwasher repair parts you may need
Replacing one of these dishwasher parts may fix your problem.
Drain Pump Replacement
When a dishwasher doesn't drain correctly, it's often due to a faulty drain pump. This can be caused by a defective motor or a damaged impeller within the pump. If the impeller is damaged, the pump may produce a loud noise. Likewise, if the motor fails to spin the impeller during the drain cycle, it may emit a buzzing sound or remain silent. Since the drain pump is challenging to reach, it's advisable to have a Sears Home Services Technician inspect and replace it if necessary.
Drain Hose Replacement
If your dishwasher isn't draining properly, a blocked or damaged drain hose may be the culprit. The drain hose links to the drain pump and directs wastewater to the sink drain. Equipped with a check valve, the hose prevents drain water from flowing back into the dishwasher once the drain cycle is complete. However, if the hose or check valve is cracked, water may flow back into the tub when the drain pump ceases operation. Since accessing the drain hose is challenging, it's best to enlist the help of a Sears Home Services Repair Expert to address any cracks or damages.
Pump and Motor Assembly Replacement
If your dishwasher isn't draining correctly, the culprit is often a malfunctioning pump and motor assembly responsible for draining the water. The motor drives a pump impeller, which in turn moves the water through the drain hose. If the impeller is damaged or if the motor isn't spinning it properly, you may notice grinding or whining noises. When faced with these issues, it's best to have a Sears Home Services Technician inspect and repair the dishwasher to address the faulty pump and ensure proper drainage.

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.
