Fisher & Paykel Dishwasher Error Code F71

F71 indicates a fill valve low current fault. The motor controller has detected that the electrical current in the fill valve circuit is below the expected operating level. This prevents the dishwasher from reliably controlling water intake, so the machine stops and displays the fault code. The issue is most often related to the wiring harness connections rather than the valve itself.

You should not continue running the dishwasher while the F71 fault is active. A low current fault in the fill valve circuit means water intake may be unreliable or uncontrolled, which could result in an incomplete wash cycle or potential water supply issues. The dishwasher should be inspected and repaired before returning it to regular use.

If the fault is limited to cleaning corroded connectors, the repair cost may only involve your time. Replacing a fill valve typically costs between 40 and 120 dollars for the part, plus labor if a technician is involved. A motor controller replacement is a more significant expense, generally ranging from 150 to 350 dollars or more depending on the model and service rates in your area.

Checking and cleaning the harness connections at the fill valve and motor controller is a task many confident DIYers can perform safely with the dishwasher unplugged. If the connections look clean and secure, testing the fill valve solenoid coil with a multimeter is the next step. Replacing the fill valve or motor controller typically requires moderate appliance repair experience and the correct replacement part.

A power reset may temporarily clear the displayed code, but if the underlying wiring or component fault remains, the F71 error will return once the machine attempts to operate the fill valve again. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The harness connections and fill valve should be inspected to address the root cause.
