Most common repairs needed to fix a Tappan dishwasher

Drain Pump Replacement

A dishwasher that’s not draining 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 connect 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.

Electronic Control Board Replacement

If your dishwasher is not draining, you can suspect that it has a defective electronic control board if the drain pump doesn’t run. The control board should send electrical current to the drain pump during the drain portion of the dishwashing cycle. A failed relay or corrupted logic on the circuit board could prevent the control board from sending electrical current to the drain pump. Determining whether an electronic control board is defective is difficult. Have a Sears Home Services Repair Expert visit your home and fix the dishwasher when it is not draining.

What to expect when you experience a Tappan dishwasher not draining issue

How is the not draining problem fixed?

Correcting most not draining problems usually involves replacing the drain pump, drain hose or electronic control board. 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 not draining

When the dishwasher is not draining 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 not draining 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.

If your Tappan dishwasher leaves a water puddle after each cycle, clogs or a failing pump could be halting drainage. Stagnant water brings odors and hinders thorough cleaning. Instead of manually scooping water, consult who to call for dishwasher repair. A quick fix restores smooth draining and fresh results.

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.
