FISHER-PAYKEL F1

Fisher & Paykel DishDrawer Error Code F1: Leak Detected — Flood Switch Triggered

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

Water has entered the base of the dishwasher and triggered the flood protection switch. The dishwasher will not operate until the water is cleared and the fault is resolved. This is a high-severity fault requiring immediate attention.

Severity

High - stop using the Fisher & Paykel dishwasher until the cause is understood or professional help is arranged.

Can you fix it yourself?

No - Professional Required

Most likely cause

Door seal (gasket) worn or damaged, allowing water to escape during the wash cycle

Estimated time for safe first checks: Professional service required.

Step-by-Step DIY Fix Guide

  1. SAFETY: Turn off the water supply to the dishwasher immediately.
  2. SAFETY: Unplug the dishwasher from the wall outlet.
  3. Do not restart the dishwasher — continued operation with water in the base can cause electrical damage.
  4. If accessible, tilt the dishwasher forward slightly to drain the base tray (place towels down first).
  5. Contact Fisher & Paykel service — the source of the leak must be identified and repaired.

If the leak warning comes back

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • If the base or floor area dries out but the code returns during the next cycle, moisture is still reaching the leak-sensor area.
  • F1 appears — always. Do not restart the dishwasher after an F1 without identifying the leak source.

The most common cause is: door seal (gasket) worn or damaged, allowing water to escape during the wash cycle.

This fault is not user-fixable and requires professional service. Contact Fisher & Paykel service immediately. F1 should not be cleared and ignored — the leak source must be identified and repaired before the dishwasher is used again.
