Most common repairs needed to fix a LG dishwasher

Detergent Dispenser Replacement

A broken detergent dispenser can prevent the dishwasher from filling with water when the dispenser shorts out and prevents the electronic control board from sending electrical current to the water valve. Corrosion or water can enter the inner dishwasher door panel to short out wiring in the detergent dispenser. The dispenser body can also crack. A crack in the dispenser housing will allow water to get into the inner door panel and short out the dispenser. Have a Sears Home Services professional examine your dishwasher and replace the broken detergent dispenser when it prevents the dishwasher from filling with water.

Electronic Control Board Replacement

When your dishwasher is getting no water, it could have a defective electronic control board. The control board sends current to the fill valve to fill the dishwasher when the control board is working properly. A failed relay or corrupted logic on the circuit board could prevent the control board from sending electrical current to the fill valve. 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 getting no water.

Water Valve Replacement

A clogged water valve is a common cause for a dishwasher getting no water. The water valve opens when it gets electrical current from the control. Openings through the water valve can easily get clogged with deposits or debris so water won’t flow through the valve to fill the dishwasher. It’s not a good idea to clear a clogged water valve because the valve can stick open and flood your kitchen. When your dishwasher won’t fill, have a Sears Home Services Tech visit your home and replace a clogged water valve.

What to expect when you experience an LG dishwasher no water issue

How is the no water problem fixed?

Correcting most no water problems usually involves replacing the detergent dispenser, electronic control board or water valve. 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 has no water

When the dishwasher has no water 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 no water 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 won’t fill leaves dishes only partially rinsed, wasting detergent and time. Clogged inlets or float switch errors commonly block water flow. To avoid prerinse hassles, schedule dishwasher repair service near me. Once water lines are clear, your dishwasher can resume effective cleaning.

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 won’t my LG dishwasher fill with water?
A defective float switch, clogged inlet valve, or a kinked supply hose can block water flow. Ensure the home’s water supply is fully open and the fill hose is not kinked.
How do I test the float switch?
Unplug the dishwasher, remove the lower access panel, and locate the float assembly. Pull up and release the float to ensure free movement. Use a multimeter to confirm switch continuity.
Could a faulty inlet valve coil stop water intake?
Yes. If the coil is burned out, water won’t enter the dishwasher. Replacing the valve typically restores normal filling.
When should I call a technician for an LG dishwasher that won’t fill?
If cleaning or adjusting the float and verifying the valve doesn’t fix it, the control board or other wiring issues may be present. A technician can test and repair more complex electrical faults.
