Fisher & Paykel soft touch dishwasher not stopping

[1mike1]

I have a Fisher and Paykel 913T soft touch dishwasher. It does not stop washing. It kept going for 5 hours the other night before we noticed it. It seeems to slowly progress through the 4 wash lights but takes over 2 hours to get to 2 wash lights. Even after this time, although the detergent dispenser has opened, the dishes are not clean.

Any suggestions? Is there a diagnostic mode on this dishwasher?

Alexa will be able to advise with regard to diagnostics, I assume he’s off being a beach bum at the moment. 😀 He should be back tomorrow night. In the meantime, check whether the machine is actually heating. The heat sequence on most dishwashers starts after the “thump” when the soap flap opens – give it ten minutes, then open the door – steam should rise. If it doesn’t, problems may lie with the heater, thermostat, controls or wiring. A process of elimination I’m afraid.

Careful with the electrics if you investigate further.

Mike,

You wouldn’t believe it but I recently had this exact same problem with our F&P 913T. Initially I thought the heater element had crapped out, so I replaced that. I still had the problem. I then thought the thermostat may be playing up, however when I changed over to the fast wash cycle after starting with the normal wash cycle it would complete the cycle with the exception of the drying at the end. 😕 This tended to indicate the thermostat was working. Also, during the drying cycle I could hear the heater relay switching in and out, but the heater element wasn’t working.

I figured the power wasn’t getting to the heater element so I pulled the printed circuit board. Lo and behold the terminal post on the back of the PC board behind the #1 connector on the vertical terminal strip had vapourised its solder. This is the main 240V supply to the heater element relay. I took the board to a mate to solder it for me and he noticed that the high current segments of the PC board had been beefed up on the outside (presumably because the normal tracks couldn’t carry enough current) but, and this is important, the quality of soldering between the terminals and the beefed up tracks was crap. I guess over time the joint deteriorated until a time where it thought enough was enough and blew out the joint. Tim resoldered the joint, adding in some resistor wire just to make sure and bingo, problem fixed.

Hope this helps.

Cheers,
