Dishwasher stood for 3 years

[Wattsy4545]

Hi, we had a great Bosch SMS53A12GB/51 (it’s maybe 8 years old now) then moved house thinking the dishwasher they’d left wouldn’t last long (and yes all the smelly water is still in there)…..three years later we’ve tried to install our Bosch. It turns on and looks like it’s about to do something but the fuse keeps blowing in the plug. Do you think it’s going to be fixable? Thanks

always a hard question
first question is what size fuse are you using as it should be brown 13A

Yes I believe so. Thanks for replying.

if its not an incorrect fuse there is not much else it can be thats cheap

on that unit the mains lead goes straight to the board, you can try removing the plug on the back of the machine and see if its blowing there, after that i would have thought anything that blows a fuse would also make a mess of the main control board

heater perhaps. These are the achillies heel of the whole sorry range. The heater / wash motor unit part number 00651956 £112.86 for your model. Beware that they are apt to fail again anything from under 3 mins to well…months..years.

discounted heater because of 2 things

1 that heater is so flimsy it would blow clear as soon as it went
2 its blowing fuses so its a live to neutral short with no mention of tripping rcd. Also it does it immediatly and unless one of the relays is welded it would wait till it had filled before blowing

Not necessarily so! Had an heat pump element go to earth in a spectacular fashion. Made pumping out noise for less than 2 secs then blew a fuse since house was trippless. Also had the sealed plug do this twice on Bosch dishwashers, looked visually fine too but were nothing of the sort. Also one where t`other end of mains lead where the lead plugs into the pcb. That one was caused by a leak ( another Bosch special )
However, I do agree that it could well be a duffy pcb it could even be a duffy board due to the heater circuit being duff too.

have had the pcb one happen, what a mess that was, tried to unsolder plug but copper tracks too big for iron so gave up and scrapped it

and as for the heater i forget tripless houses these days as there is so few of them but i shouldn’t because i have no trips at home

“have no trips at home” Me neither, the old wire fuse system has a few advantages. If I had anything super critical I would just use a plug external trip e.g. when using an electric lawn mower. My pad has never been rewired either and it will not be least whilst I own it.
