Ha Ha! Maybe it’s his plan for world domination….one dishwasher at a time!! Next thing will be fridges and another cold war……..
(I’ll get my coat!)
Well, the story continues! Took out the board and had another look. Found the heater relay now faulty! Extracted the relay from the old board – soldered it into the ‘new’ board and the machine has now been working perfectly for the past couple of weeks! I live in hope!
Well, I’ve fitted a new heater and it’s STILL not heating!! Took out the NTC and tested it with a meter. Not sure what the range should be but it’s certainly giving a reading and the resistance is changing if I hold it under hot and cold water alternately so I’m guessing its probably OK. Beginning to look like a wiring fault or possibly my board’s fried again! Not likely to be wiring – I replaced the entire loom two or three years ago! As I say, the machine seems to go thorough the programme normally – filling – washing, dispensing the detergent, pumping out normally and ending with the normal beeps. It just isn’t heating the water!!!!
Not so simple!! The machine seemed to be working fine after the replacement board and connector replacement. One week later the continuous pumping was back! Checked the base and found it full of water – regen unit leaking at the o’ rings! I wrapped the pipes with PTFE tape and slipped the o’ rings on above (to expand the o’ rings) That sorted the leak and as belt and braces I added a dab of silicone sealant on top. Another few days pass and apparently dry and working but now we have a new fault! The machine appears to be dropping the detergent tablet and stopping! The tablet is found lying at the bottom, dishes unwashed and machine cold. What on earth is it playing at now?
That’s very helpful Dave, thanks! Not the float – had the base tray out and dried. Didn’t actually check the float switch for continuity but can do to be sure. The board was definitely toast. One component burnt out / disintegrated and scorch mark on the PCB cover but connector down at the motor was also burnt out which seemed like too much of a coincidence! Connector replaced and awaiting new board so fingers crossed!
There does seem to be a bit of a leak at the regen unit – might need a new seal where it connects to the tub. Not enough to trip the float though.
