hotpoint wt 540. With mains on it takes water through but does not fill. power light flashes like a strobe, lights 3 rinse hold,and 4 mini load flash steadily . nothing else happens . It only stops if mains is turned off.
NTC. "NTC" is negative thermal co-efficient. The hotter the device gets, the lower the resistance. By comparing the resistance against a resistor array on the pcb, it is theoretically possible to get accurate temperature control.
