ok, thank you for the replies – I’ll go ahead and grab this sensor (there is an additional NTC sensor at the back of the machine near the heater element, although I don’t think that be the one at fault), and go from there.
They seem to be also having the same problem. The poster did test their sensor and found it ok, so either the heater element and sensor together or the PCB.
With my machine it appears I can buy the sensors seperately, but I’d rather be certain before I start buying random parts to “see if that fixes it”, if that makes sense?
So I thought the NTC sensor was temperature related? I would have thought in order for it to understand the lint filter needed a clean it would be looking for a restricted air flow of some kind?
