Motor controller module info for GW709

[mattgal]

Hi,

I have a F&P GW709 with a faulty motor controller board. All the fuses are OK and the machine still powers up. I looked at the board and there are some burnt components:

I tested all the diodes around the burnt area and they appear to be OK. The mosfet on the back of the PCB that feeds the cold water valve needs replacing as it is short circuited and the cold water have has a very high resistance so I’m assuming it is faulty as well. My main concern is the burnt components in the photo. One is a resistor (R848) and the other (R?) is just completely gone though I suspect it is a resistor giving its footprint.

My question is do the service manuals from F&P contain the schematics & component values for the motor controller module? Alternatively can anyone tell me what the value of R848 is and confirm the type and value of the blown component R?.

Thanks in advance,
Matt

Short ANSWER NO
We as repairers replace the module complete Although electronic experts have repaired them successfully
Be sure to check the quality of the inlet coils(64ohm) & check for cracks in the casing

Greetings,
just asking if you rec’d a reply?
I have the same PCB for repair with another fault,so can give you resistor readings if req’d,
Cheers

None of the repairers really do board level stuff – we don’t have the time. If you read back through the forum, I’m certain there’s a chap who repairs them on an exchange basis.
