Lg Dishwasher Water Inlet Valve Problems

Along with detergent and power, water is essential for any dishwasher to operate correctly. How do you fix a LG dishwasher that won’t fill? A clogged water valve could be the problem. Inspect the valve for clogs, removing any debris that could block waterflow. Determine how to check an LG dishwasher not filling with water for fast and effective troubleshooting.

Troubleshooting an LG Dishwasher Not Filling With Water

An LG dishwasher not filling with water is usually attributable to one of several common causes. We’ll detail the steps to take to diagnose the problem, including the right DIY or professional solutions.

#1. Unclog Water Inlet Valve

Is your LG dishwasher not getting water at all, or very little? The water inlet valve may be clogged. This valve opens and closes to allow water to enter the dishwasher from your home’s water supply. However, food particles, mineral deposits and other forms of debris can clog the valve and its filter, preventing water from flowing.

Follow these steps to unclog an LG dishwasher water inlet valve:

• Unplug the dishwasher and turn off the water supply.
• Locate the water inlet valve. Refer to your user manual for the valve’s location on your model dishwasher.
• Remove the valve and rinse it and its filter under running water.
• Replace the valve.
• Restore power and water to the dishwasher.

If the valve appears damaged it cannot be repaired and requires replacement.

#2. Check Float Assembly

A dishwasher’s float assembly is crucial to providing the dishwasher with an adequate water supply. The float prevents overfilling by rising with the water level in the dishwasher. Once the appropriate level is reached, it triggers the float switch to close the water inlet valve. If the float gets stuck in a low position, you’ll find your LG dishwasher not filling with enough water.

Here’s how to check an LG dishwasher float assembly:

• Turn off the dishwasher’s water and power supply.
• Remove the lower dishrack.
• Locate the float assembly on the base of the dishwasher tub. Your user manual can confirm the exact location.
• Manually lift the float to make sure it moves freely up and down.
• Remove the float from its mounting to inspect it for dirt or foreign objects, wiping away any debris.
• Replace the float and lower dishrack
• Restore power and water to the dishwasher.

If the float is damaged or doesn’t move freely despite being cleaned, it needs to be replaced.

#3. Test Float Switch

If the float assembly is working properly, it’s possible the float switch is responsible for an LG dishwasher not filling with water. This switch triggers the water inlet valve to close when the float reaches the right level in the dishwasher. If the switch doesn’t respond appropriately when the float signals the right level, it may shut the water inlet valve prematurely. This will leave the dishwasher without enough water.

The float switch is behind the dishwasher’s lower access panel. If the wires are damaged and/or the switch has a lack of continuity with multimeter testing, it requires replacement. Given the location and complexity of the repair, a professional service can best test and replace the float switch.

#4. Assess the Door Switch

When the dishwasher door closes, the latch hits the door switch, an electrical component that then signals a wash cycle to start. If the door switch is defective, it wont send the electrical signal needed for the dishwasher to start filling with water. The door switch needs to be assessed with a multimeter to determine if it has continuity. If there is no continuity, it should be replaced.
