Error code39

Quick answer
39 points first to the pressure tube: blocked with water or dirt, kinked, or fallen off.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 39 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
The pressure tube has probably become blocked, kinked or detached, or the pressure sensor is faulty.
Under 39 the manual starts with the pressure tube. The fault is mechanical and exists on Smartdrive Phases 1 through 6: the tube is clogged, bent, or has come away completely. A sound tube leaves the pressure sensor itself as a possible culprit.
Two steps in the manual
Mechanical: the tube should be whole, with no water or dirt plugging it and no kink.
Controller module: a new Motor Controller module goes in when the tube is fine; on Phase 1 the Display Module is that part.
The tube’s job
Depth of water is read by a Smartdrive as pressure, which travels to the sensor along this tube.
Owner’s reach
No part of this can be done from outside. Getting at the tube means opening the cabinet, so pull the plug first, and hand the inspection to a technician if working inside appliances is not something you are comfortable with. The code has no reset listed.
How it differs from 38
An empty reading in agitate is what sets Code 38, while 39 covers a wider set of tube conditions. The tube is where both start.
Code 40 concerns the basket, with the pressure tube named once more as a second place to inspect.
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.
