Re: Help! Hotpoint WD41 Washer/Dryer instantly tripping RCD.
Not a problem…
Thank you for all your help…!Andy.

Problem with failure of electrical filter unit KPL3008 – 4 years later!
I’ve had a similar but not identical problem to that discussed above, but with a Hotpoint WD51 that also has a KPL3008 unit fitted. Repeated attempts to switch on mains power at the wall socket to the machine, with the power switch on the machine itself either on or off, resulted only in blown 13A fuses inside the mains lead plug. After disconnecting the machine from the mains and removing the back and top covers, use of a multimeter in “resistance” mode connected to the live and neutral power leads showed no current flowing with the machine power switch set to off. (There was no current between the live power lead and the earthed chassis either, ruling out a direct short). Thus the only machine component that could be causing the problem was the electrical filter unit as it is the only one in the circuit when the machine power switch set to off.
Resistance between L and N was very close to 680 kilohms as shown by the circuit diagram on the unit casing. Unlike the problem found by Andy/Andy’s dad though the multimeter showed that the L to E and N to E resistances of the filter unit were greater than 2 megohms, which could be misinterpreted as meaning the filter was OK in that there was apparently no failure of the capacitor(s) by shorting to earth. After obtaining and fitting a replacement filter from the good people at ukwhitegoods the washer/dryer is now working. I would like to know for interests sake though which of the internal components, capacitors, chokes, resistor might have failed if anyone has any ideas…..
By the way, I would only use a multimeter in “resistance” mode if you know exactly what you are doing as some electronic components (though not the filter unit components so far as I know) can be permanently damaged even by the small DC current a multimeter will supply.
