The water supply valve is closed.

To fill your dishwasher with water, you must ensure the water supply line, and valve for replacement dishwasher parts is open. Locate the water supply valve in your kitchen and turn it loose to allow water to flow freely through the water supply line and into the dishwasher unit.

Overfill protection float is obstructed.

To prevent your dishwasher from overfilling, it’s essential to ensure the overfill protection float is in the correct position. On some models, you can find the float in the front right corner. If you have a newer model that is having trouble filling with excess water sometimes, it’s best to have a professional inspect and replace it.

To check if the float is obstructed, locate the float assembly below it and move it up and down to see if it moves freely. If you find the bottom float assembly reaches any obstructions that stop water, remove them as necessary.

A malfunctioning float switch may be interrupting the power.

A small plastic piece will float upward as water fills the tub during a dishwasher’s wash cycle. The float switch is underneath the other float switch, at the bottom of the inner door panel of the tub, which signals the water inlet. If the button is not working correctly or is damaged, it may cause triggers the float switch and water inlet valve to not open, leading to the dishwasher’s tub not getting any water.

If you encounter this problem, one way to troubleshoot it is to disconnect the float switch assembly from the dishwasher and verify if the float arm mechanically activates the float switch when it has been lifted to the same height as the top the water heater. Also, ensure that the two wires from the float arm mechanically triggers the switch and aren’t loose.

The dishwasher may not receive water due to a faulty water inlet valve.

When a dishwasher is not getting water, the most common reason is a malfunctioning water inlet valve. This often defective water inlet valve is responsible for filling the dishwasher with the appropriate hot water and is typically controlled by a timer or electronic control.

If the valve fails to open, it prevents water from entering the dishwasher. The valve can be located behind the bottom access panel at the front of the dishwasher. It has two switches: a hose that connects to the wires coming from the water line and the dishwasher, appears another that leads to the hose coming from the dishwasher tub.

If you are confident checking the water inlet valve, unplug the dishwasher and turn off the water supply before proceeding. Look for the defective water inlet valve first, typically located on the lower left-hand side of the dishwasher. You’ll need to remove the lower bottom access panel to gain access to it. Check for any signs of damage, wear, or cracking, and visually inspect the valve. If you notice any symptoms described above, the water inlet valve must be replaced.

The dishwasher may fail to fill with water due to a malfunctioning door switch.

A door switch is a component that works as an on/off mechanism, preventing the dishwasher from operating when the door is open. If the dishwasher door switch is broken or not functioning correctly, the dishwasher will not fill with water. You’ll need to use a multimeter test to test the door switch component’s probes to identify this problem.

Start by unplugging the dishwasher and opening the door. You can access the door switch in the latch assembly at the top of the door by unscrewing the inner door access panel first. Manually insert the switch and the catch into the door latch assembly and observe whether closing the latch activates both switches. If it does, use a multimeter to check for continuity in the two buttons.

A malfunctioning drain solenoid can impact the operation of the drain valve.

A drain solenoid operates the dishwasher drain valve. If the solenoid is faulty, it can prevent the drain valve and dishwasher from filling with water and working, which might be why the dishwasher is not getting water.

To diagnose and replace the power source of the appliance with the issue, check the drain valve and test the solenoid to confirm that it is still functioning properly and correctly. If it is defective, the solenoid should be replaced with a new OEM (original equipment manufacturer) part.

The cause could be a damaged water supply line.

To troubleshoot a dishwasher that’s not getting water, start by checking the water supply and inspecting the water inlet valve and hose under the sink. Ensure the hose is correctly connected without any kinks or bends blocking the water inlet valve from flowing.

Also, make sure that valve opens and the tap on the hose is turned on to the full valve open position. If you’re unsure which direction to turn the valve to open the faucet, you can try both ways and run the dishwasher to check if the issue has been fixed.
