Re: John Lewis JLWM1202 fill stops then drains and switches
The above post was over-optimistic. The machine failed again a short while ago and it turned out to be the heater thermistor, which must have been revivified when I extracted it and then checked it.
So, I fitted a replacement new heater which has fixed it.
Thanks again to all.Re: John Lewis JLWM1202 fill stops then drains and switches
Just to close this out, after testing/trying just about everything else, I thought that it could be that the pressure switch reservoir was clogged up. So, I poured a kettle of boiling water into the machine to loosen the possible clog. That worked, so the machine is now functioning. Before washing anything, I did a full boil wash cycle with detergnet only.
Thanks to all for your advice.Re: John Lewis JLWM1202 fill stops then drains and switches
To check that the valve actually works on both pre-wash and main wash inlets, I modified the pre-wash connector slightly and switched the connectors. The main wash inlet proceeded to fill properly.
Re: John Lewis JLWM1202 fill stops then drains and switches
The solenoids on both valves are showing continuity on the meter. I replaced the original which failed several months ago
Re: John Lewis JLWM1202 fill stops then drains and switches
I have now run a cold wash with all wiring discoonnect from the heater. It fills via the prewash inlet and then stops with E10.
I also rechecked the thermistor and it seems OK.Re: John Lewis JLWM1202 fill stops then drains and switches
Thanks, but I did disconnect everything from the heater before measuring the heater and the thermistor resistance. I have also extracted the thermistor and it is definitely dead.
I have ordered a replacement from this site.

I cannot see how could that account for the resistance readings that I obtained
Re: John Lewis JLWM1202 fill stops then drains and switches
Thank you.
The element resistance is about 32 ohm and the thermistor is about 4K ohm. The latter is much too low, if my web search is correct,
so am I right in thinking that I should replace the heater?
DaveRe: John Lewis JLWM1202 fill stops then drains and switches
Thanks, but since there is absolutely no direct evidence of a brushes problem and my bad back would not be too happy at my manoeuvring the machine to get access to them or remove the motor is there any other plausible cause?
