dishwasher help needed please

Airwolf1

That particular circuit the dishwasher is on may be overloaded when the dishwasher is running, if connected to the same one as kettle, washer and such like. Just a suggestion...

Sounds like the element has "Blown". The RCD trips because there is a fault to earth.
It can be repaired quite easy.

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.

You really do post some crap don't you!

If you read what the OP says carefully, it doesn't seem to be a fault to earth, because typically in a domestic situation the RCD in the consumer unit covers the whole house, unless it was fitted within the last 12 months, in which case there may be 2 RCDs.

If it's a standard MCB (circuit breaker) that's tripping, it's an over-current problem. If that assumption is correct then this is quite an unusual situation, because for a power circuit, the MCB should be rated at 30A or more. The fuse in the dishwasher plug ~should~ be rated at 13A and so should blow before the MCB trips. So it could be a problem with the wiring in the plug or the wall socket.

But better to be safe than sorry - if I were the OP I would call in an electrician to test the appliance and the wiring for faults rather than take any chances.

you have a dead short in dishwasher if your rdc did not trip the dishwasher would be alive you would get an electric shock [ a big one]

The OP's husband said it was fitted with a RCD, so that would explain why it all trips when plugging it in. It may well be a split load board and only the power trips, or it may even be a RCBO and only that circuit trips. It is unlikely (but possible) to be a MCB tripping as the local fuse would likely blow first.

Anyway, it still sounds like a blown element and shouldn't be too expensive to repair.

Yeah - but it depends what the "it" refers to.

The consumer unit or the dishwasher?

We don't know. We're just making a load of assumptions that might not be correct - hence the suggestion to call in an electrician.

first of all thank you all for your advice its very hard for anyone to really know whats wrong as im here and your somewhere else.
the plug on dishwasher is a 13amp as we changed it and tried again all plugs etc worked upstairs. so i'll maybe get an electrician out to check wiring if its the element is that for the plumber to fix in the dishwasher? sorry bit unsure and hubby at work now.

You need a domestic appliance repair man. An electrician can check your wiring but not the dishwaser.
Good luck.

espresso- you !!!!!!. Your RCD is rated at 30mA and won't save you that's 30mA going through your heart and might just take you out.
