dishwasher help needed please

crystal9

hello and hope you all had a great christmas.

on christmas day we had out electric cut out, after some time we realised it was our dishwasher doing it so id like to just see if (a big if i know) anyone could shed any light as to why it would do that, we have tried a different 13 amp in the plug, the dishwasher is not blocked as far as we can see so we are totally confused.

i'd be very greatful of any advice please

How do you know it was the dishwasher? Is it your trip switch cutting in? This may get a better response in http://forums.moneysavingexpert.com/forumdisplay.html?f=39&pp=40

If your consumer unit (what used to be referred to as a fuse box) is fitted with an RCD (if it was fitted or replaced in the last decade or more it will be) then the most likely cause will be either water leaking inside onto electrical connections or a pinholed water heating element.

Unless you have a fairly unusual consumer unit with a split load facility, this type of fault normally trips out all electrical supply to the whole house.

If it's a minor water leak you will probably be able to see evidence underneath, and it may just be that a hose needs to be replaced.

we found out as when adding certain electrical items it seemed ok then when ever we plugged and turned the dishwasher back on thats when all downstairs sockets went. all other electricals have stayed on now and we have kept washer unplugged. thanks for reply

just asked my hubby and he said it has got an rcd fitted, he did find a big sharp knife jammed at the bottom of dishwasher when emptying it this morning so maybe that has made a slight hole somewhere and caused it to leak. so does that mean i have to get a new washer?

thanks for reply

No - if the problem only took out one circuit (i.e. only a few sockets) then the RCD did not trip and your problem is probably excessive current on that circuit. If the knife was jammed under a moving part (e.g. the spray bar) then that may well have overloaded the motor, and now it's been removed you'll probably find that the problem is gone.

Hopefully!

no since removing the knife it still makes electric trip, we did plug in a new wii console the same day and hubby said it could have been that at first, its so hard as i dont want to throw away a dishwasher if theres nothing wrong. the house we're in is very dated

Any appliance in the household should be protected by RCD, however things like ovens - hot water cylinder heaters - washing machines cannot be connected to an RCD. This is because these things "leak" electrons from the heater element to the metal jacket surrounding them and trip RCD, RCDs also cause nuisance trips with appliances where earth leakage is common and not a cause of injury or mortality, such as water heaters.

hi, i dont quite understand this as it seems the dishwasher was making it trip as we now have all other plugs back in and if we plug the dishwasher in and go to turn it on it trips again
