Most common repairs needed to fix a LG dishwasher

Detergent Dispenser Replacement

If the detergent dispenser is not dispensing detergent and/or rinse aid during the cycle, a broken dispenser assembly may be causing the problem. Most detergent dispensers have internal switches along with latches and other components to dispense detergent and rinse aid at the proper times during the cycle. Because it’s hard to tell whether a broken dispenser is causing the problem, have a Sears Home Services Repair Technician examine your dishwasher and replace the detergent dispenser if it’s broken.

Electronic Control Board Replacement

When the dishwasher detergent is not dispensing, a defective electronic control board could be causing the problem. Internal logic and relays in the electronic control board send electrical current to the dishwasher dispenser to open the lid latch and dispense the detergent. Corrupted internal logic or failed relays in the electronic control board could keep the dispenser from working. Have a Sears Home Services Repair Expert examine the dishwasher and replace the electronic control board if it’s defective.

Water Valve Replacement

When the detergent dispenser isn’t working, it could have an internal failure preventing it from opening. An internal switch in the detergent dispenser releases the dispenser latch so a spring snaps the dispenser lid open during the cycle. A broken spring, bad switch or defective latch can keep the dispenser from working. Have a Sears Home Services Repair Expert replace the detergent dispenser when it isn’t working.

Sears Home Services recommendations for a dishwasher detergent that is not dispensing

When the dishwasher detergent is not dispensing 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 detergent not dispensing 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.

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.
