Re: Bosch WFL 2260 first powder marks, now no spin.
Job Done!
Her indoors is dead happy, so am I.
One of the wires on the motor end of the cable came free with a sneeze from me.
Plug remade, spin cycle worked, first load in.Re: Bosch WFL 2260 first powder marks, now no spin.
AHA!
I think I may have found the problem.
I had previously checked the winding resistances on the motor, but on checking the motor plug that connects to the processor board, one of the windings is open circuit!
So it looks like a break in the cable or a poorly made plug….. looking for a pin to help with continuity checks…. watch this space.

I was saying that I won’t be doing that!

Thanks Steve (a cockney in Oldham?),
I was gentle with the pressure switch, blowing down the pipe just sufficiently to operate the switch, without sealing my mouth over it (don’t you just love the taste of detergent)
I have also taken the processor board out now and checked it for tracking/burns – nothing obvious.When filling for a wash I can hear the drum filling and then the pressure switch cuts in to tell it’s got to the correct? level, then I hear the relays operating as for a normal wash so I think the pressure switch is working properly.
I suspect that since there are 3 relays, one of them may be duff. I think one of them must supply the motor, one must be for reversing it, and one for spin.
I’m a bit cautious of checking the motor voltage is being applied, it’s been a while since I worked with live mains circuits, I moved over to PC engineering 20 years ago.
I may just get a replacement relay from Maplin and change each one in turn, they look like basic 12volt changeover types.Re: Bosch SGS56A72GB/17 aquastop.
I found out that the O rings at the bottom of the reservoirs have leaked, causing the pool of water in the base of the machine, trriggering the leak detector and stopping it working.
I removed the reservoirs and cleaned the crud out and reseated the O rings – no leaks now, machine seems to work fine, except it’s not draining properly now.
Is there a ‘total reset’ for this machine?
