Mystery delay before activity in a Carlton CF/CS dishwasher

[RodTungsten]

A strange problem with this dishwasher (no model number on the front or top but the document gives CF1W and CSI1S).

Putting the programmer to any cycle – rinse, wash etc and turning on via the push button results in silence. Go away for 30 min and return to find the machine has rinsed or is running. It’s almost as if it is too shy to show it can work.

I suspected that this had something to do with softener regeneration so refilled (but salt OK) and topped up rinse aid, washed filters etc – all done regularly anyway – but to no good effect.

Any clues as to what to look at?

Door spring cords have broken twice on this machine (a chafing fault) – breaks with a noise like a rifle shot. Fixed with spare bits of clutch cable from my classic race bikes and a short length of copper microbore pipe as a cable loop clamp.

I think you’ll need to give us some more info – the numbers quoted don’t seem to come up. Worth checking around the edge of the inner door for a rating label. Carlton is a Curry’s brand name, so it’s a “proprietary” machine with a badge stuck on it. If we can work out what the base model is we can get somewhere.

No other details or markings on this, I’m afraid (it was a cheapo ex-demo model and maybe kids pulled them off).

However, back this AM from a weekend away and decided to investigate. Took the top panel off (isolating first, of course!) and poked about a bit with a meter. Suspected the rocker switch actuated by the door handle. Dismantled the mechanism and sprayed into the microswitch with contact cleaner and then gave the switch a good working over.

Reassembled and hey presto – it now works on command.

I guess the micro switch mechanism became sticky over time and would only make contact after a delay.
