Whirlpool Dishwasher Error Code F6

F6 means the dishwasher attempted to fill with water but the control board could not confirm water flow. The inlet solenoid valve (WV1) is being energized, but the flowmeter (FM) is registering fewer than 10 pulses in 10 seconds and the water presence indicator (WI) shows a low state. The machine stops the cycle until the fill problem is resolved.

A reset may temporarily clear the error code display, but F6 will return at the next fill cycle if the underlying problem is not corrected. The control will detect the same missing flow signals and halt again. Resetting is useful for confirming whether a one-time supply interruption caused the code, but it is not a fix for a failed valve or flowmeter.

If the fix is simply opening a closed water tap or clearing a kinked hose, there is no parts cost involved. Replacing the inlet solenoid valve (WV1) typically runs in the range of $30 to $80 for the part, while a flowmeter (FM) replacement is generally in the $20 to $60 range, with labor costs added if a technician performs the repair. Total repair costs with professional service commonly fall between $100 and $250 depending on the failed component and local labor rates.

Start by confirming the water supply shutoff valve is fully open and checking the inlet hose for kinks or blockages, including the filter screen at the valve inlet. If the supply is fine, the inlet solenoid valve (WV1) or flowmeter (FM) likely needs to be tested and possibly replaced. A qualified technician can check solenoid resistance and pulse output from FM to pinpoint the faulty component.

The dishwasher is designed to stop the cycle when F6 is triggered, so it will not run a wash without water. However, repeatedly attempting cycles with an unresolved F6 can stress the control system and motor components. It is best to diagnose and correct the issue before running the appliance again.
