Common dishwasher repair parts you may need
Replacing one of these dishwasher parts may fix your problem.
Drain Pump Replacement
When your dishwasher doesn't drain properly, it's likely due to a malfunctioning drain pump. This could be because the drain pump motor is faulty or the impeller inside the pump is damaged. If the impeller is damaged, the drain pump may produce a loud noise. Alternatively, if the motor isn't spinning the impeller during the draining phase of the dishwashing cycle, it may either emit a buzzing noise or remain silent. Since the drain pump is difficult to reach, it's best to have a Sears Home Services Technician examine it and replace it if necessary.
Drain Hose Replacement
When your dishwasher doesn't drain properly, it might be due to a cracked or clogged drain hose. This hose connects to the drain pump and transports wastewater to the sink drain. Equipped with a check valve, the drain hose prevents drain water from flowing back into the dishwasher once the draining process is complete. However, if the hose or check valve is cracked or damaged, water can flow back into the tub when the drain pump stops. Since accessing the drain hose can be challenging, it's best to have a Sears Home Services Repair Expert address any cracks or damage in the hose.
Electronic Control Board Replacement
If your dishwasher isn't draining, and the drain pump isn't running, it's possible that the electronic control board is defective. Typically, the control board sends electrical current to the drain pump during the draining phase of the dishwashing cycle. However, a malfunctioning relay or corrupted logic on the circuit board might hinder this process. Diagnosing whether the electronic control board is faulty can be challenging. To address this issue, it's recommended to have a Sears Home Services Repair Expert inspect and repair the dishwasher if it's not draining properly.

What you should look out for with a dishwasher not draining diagnosis
Diagnosing issues with modern appliances can be challenging without the right knowledge and training. Simply replacing parts without proper diagnostic techniques may not solve the problem. Appliances, particularly those made in the last decade, have advanced significantly, with electronic components that are hard to assess. DIY repairs on these latest models are becoming more complex.

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.
