Bosch Dishwasher classixx blows fuse when turned on

Hi, I have inherited a Bosch dishwasher madel no sgs43a52. It is not working andwhen I switch it on it blows the RCD in the house fuse box. I cant find any repair manual or even a user manual for this machine. It is only about 4 years old and has had very light use, being in a holiday home all its life. Any ideas? Even a description of how to open it up to check the motor connections and heating element would help. Thanks for your time Thinking Hard...

    I have just taken the top and right side panel off the machine, and find the pump has a fair amount of rust around it and the bottom of the plastic floor panel is covered with what appears to be salt crystals. It is damp/wet.
    I am wondering now if the pump is leaking. If the water is running through the pump and taking the salt from inside the dish washer with it, maybe this is the problem.
    Is this a likely cause? Can I just hose out the bottom of the machine? (I might even take it outside first...) How easy is it to replace the pump.
    Any other thoughts???
    Still Thinking Hard

    Thanks Crytech, Do I need to strip the machine in to pieces to get access to these parts? I have not removed the left hand panel yet, but that should be straight forward enough. What then tho...
    Does the softener have a tank, Is that going to come off easily?
    Thanks for your help.

    Thanks for that. Took it out side, turned on its side, took off hoses, un screwed, loosened, shook, pulled, pushed slipped, scratched hand, swore, jumped about a bit, pushed again, lifted, and removed plastic bongos. (cracked before i started application of common sense).

    Will be reversing the order of events when the replacement bongo's arrive.

    Strange thing, the guy at the parts place didnt recognise the tech term for the softener unit. Said they were a appliance parts store, not anything to do with MUSIC... Dont know what he's on about...

    Thanks for the advice, Got me out of a hole :-)

No don't hose it out. That will only make things worse. There are a good number of reasons why it may be blowing the breaker. You will need to meter out the different parts to check for a short. My guess from you description is that the softner unit has broken / leaked and gone into the main pump. You will need to replace both if thats the case.

    The softner unit is the plastic bongo's looking tub under the machine and the neck of one side protrudes into the bottom of the machine itself - this is where you put the salt into. The other half contains a browny / orange / yellow crystals ( we call resin) water pases through this & the calcium is removed from the water(softening), the salt (or salt water) the machine uses to clean the calcium resin crystals for the next time it fills. The softner will be held into position with a locking nut around the neck of where you put the salt in and perhabs with a bracket underneath. Just remove all hoses to the softner unit & it should come out pretty easy. Common sense with get you through this one!

    The machine is best serviced from the bottom, so lie the machine down.

    Good luck & enjoy!!!

Call a plumber to check your water pipe or you could twist the tap cap back and fort. Runs the dishwasher, if no water still. change FILL VALVE this is an electro-mechanical device that opens a valve to allow water to flow.
May also be called a WATER VALVE or WATER FILL VALVE.
If this does not solve the problem , you need to change the control board.
