Hi. I have a F&P GW609NZ. The motor control board blew up recently, and I’ve now installed a locally refurbished board. I did all the checks re ohms of motor windings, pump etc, and all seems OK. On connecting power it seems OK, all the LEDs light then go out, then it looks just like it used to. But when I try to set it going, the inlet valve(s) give very short pulses, and after a short time it just stops and starts beeping. I’ve gone into diagnostic mode, and I have the far left LED and the 2 far right LEDs lit. Reading the forums I think I need to read from right to left, which makes 11000001. Is this Fault Code 131? And what might that indicate?
Thanks for any help

Rotor position sensor error (repetative). Sensor is next to the stator windings – check for chaffed, broken, corroded wiring, especially where the loom turns under the drum. If there’s dampness, find the leak. Sensor itself may be faulty.

Re: GW609 fault code?
That was quick! Thanks. After reading your “rapid response” I took the motor coil thing off the bottrom, to get at the sensor. The wiring loom looks fine, and I checked continuity of the wiring between the plugs on each end of the loom… 5 wires all OK. So does that suggest the actual sensor (a small PC board?) clipped onto the motor coils is faulty?
Thanks

*Probably*……… No way to be sure without the dedicated, only available to F+P engineers, test tool……..

I have one here with the same problem code. On close inspection after removing the rotor position sensor board from the plastic clip, it looks like the varnish insulation on the board is very dodgy, and it’s arced / tracked across to the stator windings or cores, and the hall transistor (? -if that’s what it is) on the “c prong” seems to have fried. It doesn’t look like there’s been leakage from the shaft seals, so presumably condensation got to the insulation / corroded the board.
There’s several different rotor position sensors on F&P parts lookup, but the number marked on the board (425937A) doesn’t score a hit.
One of the likely looking parts leads me to a 420296P – ROTOR POS SENSOR MK2. If that’s it, then I hope that the “Mk2” version has better insulation varnish on it.Perhaps someone else reading this has has experience with the same. I’m 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure the sensor is dead but I’m not sure that if this is right, then it may have also fried something on the main board. The stator windings look fine in the area where it’s arced across, but I’d clean it up and paint some epoxy resin over the windings in that area before reassembling.
I don’t like the machine much – IMO it’s always been rough on clothes, and very bad for lint. My wife would be happy if someone here would tell me to forget about fixing it.

Thanks for that. It’s not showing up by that number on local parts distributor’s site – but I’ll give them a call in the morning.

Part number here (New Zealand) is 420296P.
That supersedes several earlier parts, and is apparently used on current models. It is the “Mk II” version.
Obvious design change is that the PCB conductors on each of the 3 “prongs” on the board are inset to the center of the prongs – rather than at the edges which led to the failure with the original as they were too close to the stator windings.
Cost ~ NZ$58 (retail).
Installed and working fine.Oops…
Close inspection after reassembling, and there was some leakage from seal. Replaced bearings & seal, still working fine and hopefully might continue to do so for another few years.Re: GW609 fault code?
I got bored with the GW609 problem, so gave up and bought a new Simpson (so far so good). But I want to have one last try to get the GW609 going (for my daughter). It has the new refurbished motor control board, plus I did buy and fit a new RPS (Mk 2) board from F&P locally ($60)… but still no go. Machine turns on normally, but when a wash cycle is tried, water valves just give the same short pulses, then it gives up and beeps, and shows the same error code lights as before (1 far left, and 2 far right which I understand to be error 131. Any other ideas appreciated.
Thanks.
