Most common repairs needed to fix a LG dishwasher

Pump and Motor Assembly Replacement

A dishwasher that is leaking could have a faulty pump and motor assembly. A bad water seal or crack in the pump housing could be causing water to leak out of the bottom of the dishwasher. As soon as you see a leak, you’ll need to act quickly to prevent damage to kitchen flooring and counters. Schedule a Sears Home Services Repair Technician to visit your home and examine your dishwasher. The technician will replace the pump and motor assembly if it’s the source of the leak.

Electronic Control Board Replacement

A leaking dishwasher could have a defective control board. The control board sends electrical current to the water fill valve to fill the dishwasher. If the electronic control board doesn’t shut off the current supply to the fill valve properly, the dishwasher could overfill and begin leaking. When you see your dishwasher leaking, schedule a Sears Home Services Repair Expert to visit your home and find the source of the leak. The technician will replace the electronic control board if it’s defective.

Door Seal Replacement

When you find your dishwasher leaking, you can suspect that a worn or damaged door seal is causing the problem. The rubber gasket that surrounds the tub opening keeps water from leaking out of the dishwasher when the door is shut. A worn or damaged seal will allow water to leak through the edges of the door. When you discover a dishwasher leak, have a Sears Home Services Technician visit your home and replace the door seal if it’s leaking.

What to expect when you experience an LG dishwasher leaking issue

How is the leaking problem fixed?

Correcting most leaking problems usually involves replacing the pump and motor assembly, electronic control board or door seal. 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 leaking

When the dishwasher is leaking it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling LG dishwasher repair with a local Sears Home Services professional who can 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 leaking 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.

An LG dishwasher that leaks can drip beneath cabinets or warp flooring if overlooked. Common causes include brittle door gaskets, cracked pumps, or loose hoses. Instead of living with puddles after every load, contact a dishwasher technician. A thorough inspection seals up trouble spots and ensures your LG runs efficiently.

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.

Frequently Asked Questions

Why is my LG dishwasher leaking water?
A damaged door seal, cracked tub, or loose plumbing connections can cause leaks. Check the door gasket first for wear or tears.
How do I confirm the door gasket is the problem?
Look for visible cracks or flattening. If damaged, pull out the old gasket, clean the channel, and press a new gasket into place evenly.
Could overloading create leaks around the door?
Yes. Overfilling or improperly loading dishes can force water against the seal, leading to spills. Follow manufacturer guidelines for load capacity.
When should I hire a pro for an LG dishwasher leak?
If you’ve replaced the gasket, checked hoses, and adjusted loading without success, the pump or tub may be damaged. A technician can handle more complex leak sources.
