Dishwasher Not Filling With Water? Fix Your No Water Flow Issue

By Fix4U Team
Dishwasher, Kitchen Appliances

You start up your dishwasher expecting it to begin washing with a steady spray of water. Instead, the tub remains dry and no water enters the appliance throughout the cycle. Lack of water flow is a common dishwasher problem that prevents dishes from getting properly cleaned.

There are several components involved in delivering water to the dishwasher tub. When one fails, it can stop water from entering the unit. In this article, we’ll cover how to diagnose and address water supply problems with your dishwasher.

Why Your Dishwasher Isn’t Getting Water

Here are some of the most likely reasons your dishwasher won’t fill with water:

Clogged Water Inlet Valve

The inlet valve controls water flow into the dishwasher. Mineral deposits and debris can clog the valve, preventing it from opening to allow water in.

Faulty Inlet Valve

In addition to clogs, the inlet valve can malfunction electrically and fail to open. This is a common failure point.

Disconnected or Leaking Water Supply Line

For water to reach the valve, the dishwasher must be properly connected to the water supply line. Leaks and disconnects stop water flow.

Clogged Water Valve Filter

Most inlet valves have a fine mesh filter screen to catch debris. If excessively dirty, the filter will block water flow.

Defective Water Pump

If the circulation pump responsible for spraying water during the wash cycle fails, water won’t enter the tub.

Damaged Float Switch

The float switch stops water from overflowing the tub. If stuck, it will shut off the inlet valve and prevent filling.

Faulty Door Switch

To start the fill cycle, the door switch must engage. Problems with the door latch or switch will stop water flow.

Bad Control Board

The control board can fail to send voltage to activate the fill valve. This halts water from entering the tub.

Troubleshooting No Water Flow Into Dishwasher

Follow these steps when your dishwasher won’t fill with water:

1. Check Water Supply Line

Verify the water supply is turned on fully and the dishwasher line is not kinked or disconnected.

2. Clean Inlet Valve Screens

Remove any debris clogging the inlet valve filter screens. Soak in white vinegar if mineral buildup.

3. Test Inlet Valve

Use a multimeter to check for power to the inlet valve during the fill cycle. If none, replace the valve.

4. Examine Float Switch

Check the float moves freely and is positioned correctly. Replace faulty switches.

5. Inspect Water Pump

If the circulation pump is not activating, the dishwasher won’t start the fill cycle. Replace faulty pumps.

6. Check Door Latch

Confirm the door closes properly to engage the door switch. Adjust or replace defective switches.

If water still won’t flow into the dishwasher, the control board likely needs diagnosis and replacement by a technician.
