Fisher & Paykel DishDrawer Error Code F2 — Water Overflow / Excess Water
What this means
Error code F2 on Fisher & Paykel DishDrawer dishwashers indicates the water level inside the wash tub has exceeded the maximum allowable level. This is detected by the pressure sensor or water level switch. The most common causes are a faulty water inlet valve that is not shutting off properly, a blocked or kinked drain hose preventing proper drainage, a failed water level sensor (pressure switch), or a siphoning issue where water backflows from the sink drain. The unit will attempt to activate the drain pump to lower the water level.

Step-by-step fix
4 stepsCancel the cycle and drain
Press and hold the Power button to cancel the current cycle. The drain pump should activate and begin removing excess water. If the drawer does not drain, turn off power at the breaker, open the drawer, and bail out as much water as possible with a cup and towels.
On dual DishDrawer models, only the affected drawer will show the F2 code — the other drawer can continue operating normally.
Check the drain hose and spigot
Inspect the drain hose at the rear of the DishDrawer for kinks, blockages, or improper routing. The hose should have a high loop or be connected to an air gap to prevent backflow. Ensure the spigot connection on the sink drain or garbage disposal is clear and not clogged with debris.
A common cause of F2 on DishDrawers is a missing high loop in the drain hose. The hose must loop up near the countertop level before dropping down to the drain connection.
Test the water inlet valve
Turn off power and the water supply. Disconnect the water inlet valve wiring harness. Use a multimeter to test the solenoid coil — it should read between 500 and 1500 ohms. If the valve reads open or significantly outside range, replace it. Also check if the valve physically shuts off by closing the water supply, disconnecting the inlet hose, and looking for drips.
A water inlet valve that does not fully close will slowly fill the drawer even when it is off — this can trigger F2 between cycles.
Inspect the pressure sensor
Locate the pressure sensor tube connected to the sump area. Ensure the tube is not kinked, blocked, or disconnected. Blow gently through the tube to verify it is clear. If the tube is clear but F2 persists, the pressure switch itself may need replacement.
Detergent residue can clog the pressure sensor tube over time. Flush it with warm water if you suspect a partial blockage.
When to call a professional
If the water inlet valve is not shutting off and you are uncomfortable replacing it, or if the pressure sensor system appears to have an electrical fault, contact a Fisher & Paykel authorized service technician.
