KitchenAid Washer Error Code FH

The FH code means the washer did not detect water entering the machine or the pressure switch did not trip after the inlet valves were open for 8 minutes and roughly 10.5 gallons passed through the flow meter. The washer expects both the flow sensor and the pressure switch to confirm that water is filling the tub. When that confirmation does not arrive in time, the machine stops and displays FH to alert you to a water supply or sensing problem.

Resetting the washer may clear the code temporarily, but it will return if the underlying cause is not corrected. The control board triggers FH based on a real-time failure condition detected during the fill cycle, so the code will reappear on the next wash cycle if the water supply issue or faulty component is not addressed first.

If the fix is as simple as opening a supply valve, cleaning hose screens, or straightening a kinked hose, there is no parts cost. If the water inlet valve assembly needs replacement, parts typically range from $30 to $80 depending on the model. A flow meter or pressure switch replacement generally falls in a similar range, and adding professional labor can bring the total repair cost to $100 to $250 or more.

Start by checking that both hot and cold water supply valves behind the washer are fully open. Then inspect the inlet hoses for kinks and remove them to check the small filter screens inside the inlet valve connections for clogs. If the supply side looks good, the inlet valve assembly, flow meter, or pressure switch may need to be tested and possibly replaced.

You should not attempt to run a wash cycle while the FH code is active. The washer stops the cycle specifically because it cannot confirm that adequate water is present, and running the machine without proper water levels can stress the motor, pump, and other components. Resolve the water supply or sensor issue before using the washer again.
