Fisher & Paykel DishDrawer Flood Protection Sensor — Safety Notices safety notice from the Fisher & Paykel repair guide.
Fisher & Paykel DishDrawer models include a built-in flood protection sensor in the base of the unit that detects water accumulation beneath the drawer cavity. Understanding how this system works helps homeowners respond correctly when the sensor is triggered and avoid unnecessary flooding risk.
Why It Matters
When the flood sensor detects water in the base tray, the dishwasher will shut down automatically and may display an error code such as F1 or Flood on the control panel. This is a safety feature, not a malfunction. Ignoring a triggered flood sensor or resetting it without investigating the source of water can lead to progressive leak damage.
What to Check
- If the flood indicator activates, turn off the water supply valve under the sink immediately.
- Tilt the DishDrawer unit slightly forward to drain accumulated water from the base tray — this resets the float switch.
- Inspect the door gasket, sump seal, and water inlet connection for signs of leakage.
- Check that the drain hose is not kinked or elevated higher than the unit's drain port.
- Run a short rinse cycle after reset and observe for any recurrence of the error.
When to Call a Pro
If the flood sensor triggers repeatedly or you cannot identify the leak source, stop using the appliance and contact Fisher & Paykel service at 1-888-936-7872.
