Quick answer

Fisher & Paykel DishDrawer alert F21: typical presentation, safe checks, and when to call an independent tech.

Model compatibility: Fisher & Paykel reuses codes across series and model years, so F21 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Before you call

Safe checks you can make

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

  • Do not attempt to enter or interpret the service/diagnostic mode yourself.
  • Note when and how F21 appeared (which cycle stage, what the drawer was doing) for the technician.
  • Switch the appliance off at the wall if it is behaving unsafely, and avoid further cycles until it has been checked.
  • Record the full model and serial number from the rating plate.

Important safety warning. Service/diagnostic codes are for trained technicians using official test procedures. Do not open panels, access wiring, or attempt to force the appliance into a diagnostic mode. If you notice smoke, sparks, or a burning smell, disconnect power at the wall if safe to do so and call a professional immediately.
