Fault 11 on a Fisher & Paykel washer is a negative pressure reading while the water level is measured. The manual's first step is the pressure tube.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 11 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
Pressure sensor fault: the Motor Controller detected negative pressure while measuring the water level, on Phases 1 to 6.
The cause named in the manual
Fisher & Paykel’s service manual links fault 11 to one particular act: re-attaching the pressure tube at the sensor when water was still part-way up the bowl. For that reason the tube is the primary source: a narrow hose that delivers water-level pressure to the sensor.
What the washer noticed
A Smart Drive washer measures the amount of water in its tub with a pressure sensor. For fault 11 the Motor Controller micro registered negative pressure, which is nonsense for a tub of water. Phases 1 to 6 are listed.
The manual’s steps
Make sure the bowl is completely pumped out.
Take the pressure tube off the pressure sensor, drain any water from the tube and put it back.
Fault still showing: replace the Motor Controller module (on Phase 1 that is the Display module).
The instructions assume a technician who can work inside the machine, and the third is a part replacement. An owner should cut power at the wall and leave it to service.
Reason for the order
Pumping out first matters because reconnecting a tube with water in the bowl is just what the manual ties to this code.
Book through (310) 872-1939 in Los Angeles, and say if the washer had recently been serviced or moved before the code appeared. See the washer repair page for the service itself.
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.
