Smeg dishwasher DF612 SDX7 – constant drain out

[twicknix]

Apparently I am the third engineer that the customer called out, the first two turned up and saw the dishwasher and says “nah, I don’t do Smeg” then charged her for the visit and buggered off without even opening up the dishwasher. Whereas I came in, pulled the dishwasher out and inspect it, according to the customer that I am the only guy to actually bothered to look at it. I am rather annoyed with the first two engineers for giving us engineers who actually bothered to investigate.

The trouble with the dishwasher, according to the customer that it just continues pumping out. No water on base, no evidence of water being on the base prior to evaporation. Heater is fine, motor appears to be in working order according to the readings. PCB module appears to be sound.

No error code lights to give me any indications. The dishwasher have been out of action for 3-4 weeks. Any ideas?

check for shorted pump triac on the board

I couldn’t see burnt tracks on the board at the time but I did suspect it could be the board being the problem. The customer’s experiences of two engineers letting her down left her feeling nervous, I am trying to find a low cost route for her and did mention that there is a possibility that the board is the culprit. She felt that she waited long enough with the broken dishwasher and is very eager to replace the dishwasher with anything but Smeg due to the reasons of engineers refusing to come out. I explained that Smeg in general as a whole are decent and very rarely I come out to it perhaps they are few and far between. I don’t have a problem with Smeg dishwasher. Thank you for the suggestion by the way.

you wont always see a burnt track if a triac fails. Sometimes they just fail because they want to. If it is a triac it will be a very cheap option as they are not expensive and even cheaper if you take it off an old board
