Dishwasher: Why won't my dishwasher fill?

A dishwasher that doesn't fill with water when you press Start is little more than a place to hide dirty dishes. First, make sure that the water supply cut-off valve is open. If it is, try this easy fix: check whether an object is preventing the overfill float from moving up and down freely. If the float is stuck in its highest position, the fill valve won't let water into the tub.

If that doesn't take care of it, the overfill float switch or water inlet valve may be broken. A failed electronic control board or timer could also prevent the dishwasher from filling. Watch the dishwasher not filling video for more troubleshooting tips to resolve this problem.

Replace the dishwasher water inlet valve

The water inlet valve, also called a solenoid fill valve, controls the flow of water into the dishwasher by opening and closing. If the water inlet valve doesn't open at all, water can't flow into the dishwasher. If it opens partially, the dishwasher won't fill adequately, and the water level will be low--a noisy pump is one indication that the water level is low. Conversely, if the water inlet valve won't close, water fills the dishwasher tub even when the dishwasher is off. If the water inlet valve doesn't open or close correctly, repair or replace it.

Replace the dishwasher overfill float switch

The overfill float switch is located under the tub and is attached to the mushroom float inside the tub, which rises and lowers with the water level in the tub. When the overfill float switch detects that the water level is too high, it shuts off power to the water inlet valve, stopping the flow of water into the tub. Even if the mushroom float is working properly, the micro-switch could have failed. Replace the micro-switch if it fails.
