Fisher & Paykel Dishwasher Error Code F1

• Verify the dishwasher power cord is firmly connected to the wall outlet and that outlet is functioning properly • Confirm the dishwasher door is fully closed and the door latch engages completely with an audible click • Locate and open the water supply valve under your sink—turn the valve handle counterclockwise to ensure water flows fully • Inspect both hot and cold water inlet hoses connected to the dishwasher for kinks, twists, or pinches along their entire length • Check the inlet hose screens at the connection points (behind the dishwasher where hoses attach) for debris or mineral buildup by disconnecting the hoses and rinsing the screens • Remove and inspect the dishwasher filter at the bottom of the tub—rinse thoroughly under running water to remove food particles and debris • Examine the spray arms for clogs in the spray holes—soak in hot water and use a small brush to clear any blockages • Confirm you are using the correct amount of dishwasher detergent as recommended for your model and water hardness • Check your home's circuit breaker panel to ensure the breaker serving the dishwasher has not tripped—reset if necessary • Perform a complete reset by switching off the dishwasher circuit breaker for 60 seconds, then turning it back on to allow the system to reinitialize • Run a short test cycle to observe if water fills normally • If the F1 error persists after all checks, contact a professional appliance repair technician to diagnose the inlet valve, control board, or sensor components
