KitchenAid Dishwasher F6E4 Error — Fix

What Does This Error Mean?

KitchenAid dishwasher F6E4 error means the machine could not fill with water within the allowed time. Check that the water tap under the sink is fully open and that the inlet hose has no kinks.

Affected Models

KitchenAid Built-In Dishwasher
KitchenAid Top Control Dishwasher
KitchenAid Front Control Dishwasher
KitchenAid KDTM Series Dishwasher

Common Causes

Water supply tap under the sink is closed or partially open
Kinked or crimped inlet hose
Blocked mesh filter on the inlet valve
Low household water pressure
Faulty water inlet valve solenoid

How to Fix It

Check the water supply tap.

Open the cabinet under the sink and locate the supply tap on the hot or cold water pipe connected to the dishwasher inlet hose. Turn it fully counter-clockwise to open. A partially open tap is a common cause of F6E4.
Check the inlet hose for kinks.

Pull the dishwasher slightly forward and inspect the braided or rubber inlet hose. Straighten any bends or kinks. Also check the hose has not been pinched by the machine being pushed back against the cabinet.
Clean the inlet valve mesh filter.

Turn off the water supply tap. Unscrew the inlet hose from the back of the dishwasher. Inside the inlet port there is a small mesh filter. Remove it carefully, rinse it under running water, and refit.
Reset the dishwasher.

After checking the water supply, hold the cancel or reset button for 3 seconds to clear the F6E4 code. Restart a normal cycle and check that the machine fills.

When to Call a Professional

If the tap is open, the hose is straight, and the inlet filter is clean but F6E4 persists, the water inlet valve solenoid has failed and needs replacement.
