Our Fisher & Paykel GWL08-US1 suddenly stopped toward the end of a heavy wash load, part way through the spin cycle, with a fraction of the rinse water still in the tub, and has refused, thus far, to ever spin again. No main motor turning, no pump motor.
It makes a slight noise, seemingly in an effort to move, when power is turned off, then cycled to the spin stage. This noise/effort can be reliably reproduced.
Eventually, after obtaining the F&P manuals, I ran the diagnostic program and got fault 131. Following this clue, I then dug out the Rotor Position Sensor and found that one of the three sensors, the one closest to the phase connectors, is charred, perhaps because of arcing between the adjacent stator pole and a circuit trace on the RPS’ printed circuit board, or perhaps between the stator pole and a device on the printed circuit. (The device may have just blown up, too, all by itself. I can’t really tell for sure. )
One post that I read suggests that if the RPS is fried, the Motor Control Module is also fried. Lacking a schematic of the Motor Control Module, I can't judge whether a fault of this type at the RPS is likely to damage the Motor Control Module, or what measurements to make to determine whether the Motor Control Module is functioning.
All front panel controls seem to have the expected effect on the display, but because the motor does not rotate, nothing happens in response to the controls, other than that the front panel display lights, happily light and extinguish just as they should.
Is the Motor Control Module likely dead? Is it worth gambling a new RPS, - or is this a lost cause and time to give the machine a decent burial?
If the Motor Control Module is shot, it probably isn’t worthwhile to try to repair it. The machine is twelve-fifteen years old.
On the other hand, it is in good shape, if one overlooks the fried RPS’ disappointing lack of enthusiasm.
