Code 5 reports the Phase 1 communication fault from the Display Module, with a reset, a 12 way harness check and a moisture check.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 5 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
A Phase 1 Smartdrive Display Module struggled to communicate with the Motor Controller.
Display view of the link
Code 5 mirrors code 4. On Phase 1 the Display Module is the unit reporting a struggle to communicate with the Motor Controller, and the manual treats the display as the primary source.
Steps in the manual
Power off at the wall, wait 5 seconds, power on, and try again.
Examine the 12 way harness, looking for corroded or poor contacts.
Look for moisture around the console, and dry the area if needed.
With the fault still there, replace the Display Module.
If it persists after that, replace the Motor Controller; should the new unit clear the fault, the original goes back in.
Where an owner fits in
Only the first step is free to try. Examining the harness and the console for moisture both mean opening the console, and the manual gives no owner method for drying it out. If a reset leaves 5 showing, the remaining steps are for a technician.
Difference from code 4
Code 4 starts from the Motor Controller and is silent on harness or moisture. Code 5 starts from the Display Module and covers both. The manual lists the two as separate faults, so the number on the screen decides which list gets used.
