Dishwasher starts but no water enters
Cycle runs dry with no washing action
Dishwasher hums but does not fill

Dishwasher stops early in the cycle

Most Common Causes

Bad water inlet valve – one of the most common reasons a dishwasher will not fill.
Clogged inlet screen – debris can block water flow into the machine.
Faulty float or float switch – may incorrectly signal that the dishwasher is already full.
Door latch issue – some models will not fill if the door is not latched properly.
Water supply problem – shutoff valve or supply line may be restricted.

Most Common Fix: Replace the Water Inlet Valve

If your dishwasher is not getting water, the water inlet valve is one of the first parts to inspect. A failed or restricted valve can stop the dishwasher from filling and starting the wash cycle correctly.
