Code 55 is the System Step Fail entry; the rotor position sensor is its only named source.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 55 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 system step fail on Phases 3 to 6, with the rotor position sensor named as the primary source.
The entry in brief
System Step Fail is the title of code 55, which covers Phases 3 to 6. The manual has no description paragraph for it. It supplies only the Rotor Position Sensor as the primary source, plus two checks.
Checks listed
Wiring of the motor and of the Rotor Position Sensor.
The Rotor Position Sensor itself, using an RPS Tester.
Gaps in the manual
No secondary or tertiary source is given, and nothing explains what causes the step to fail. The entry ends where the manual ends. Codes 53 and 54 have longer lists, and a technician may compare against them.
Phase 4 falls inside the range
The code starts at Phase 3, so Phase 4 machines are included. The manual’s Phase 4 models are GW708, GW608, W508, MW058, LW085, AW085, GWC08, GWM08, GWL08, THM08 and THL08.
If both checks pass
Sound wiring and a sensor that passes the tester leave no further step in the manual.
Owner note
The sensor check needs an RPS Tester. The manual gives no reset and no user check, so noting the code and the model is the useful part.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
