Fault 6 is a wrong signal from the pressure sensor; the manual's action is to replace the module that received it.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 6 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
An incorrect signal from the pressure sensor reached the Motor Controller (the Display on Phase 1), listed for Phases 1 to 4.
Which module received the signal
On the display a lone 6 can be confused with other numbers. The manual defines it as an incorrect signal from the pressure sensor. Phase 2 to 4 washers register it in the Motor Controller module, whereas on Phase 1 the manual puts it in the Display module.
The sensor involved
A tube connects the pressure sensor to the tub, and it measures the water level. The manual says the signal was incorrect and gives no reason beyond that.
Entry summary
Source named first: Motor Controller module, or the Display module on Phase 1.
Remedy: replace that module.
Covers Phases 1 to 4.
There is no tube check listed under 6. Tube faults are filed under the other numbers below.
Generation matters
One number can point at a different module depending on the washer’s generation. The fault list is grouped by Phase 1 to 6. The model table puts the GW500, GW600 and GW700 families in Phase 1 and the GW701, GW601 and GW501 in Phase 2, so identify your washer first and only then read the replacement advice.
Separating look-alike numbers
2: failure while the pressure sensor was being read.
11: negative pressure seen while the level was measured.
A 6 that keeps returning can be reported to (310) 872-1939; the washer repair page covers the appliance in general. Read the model number from the label before ringing.
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.
