Question about Bosch Washing Machines
Hi, yes as you have discovered the only thing that can or will trip a breaker or blow a fuse, is some sort of dead short, or close to it, across the line. from Phase to Neutral/Earth.
Usually then the problem is the bridge rectifier, and or some other components in the PSU Main Board.
As it is a short, it usually isn't too hard to find with a meter, set to OHMS. Metering IN, from the P & N terminals one should be able to find the short, and replace the components.
However components usually do NOT just spontaneously fail, indeed they do sometimes, but more often than not, there is either an external cause, power spike, surge etc. or an internal cause that caused too much current draw. Also there may be "Collateral" damage too, in any event, again usually the "Other" components on the main board will have been overstressed, and prone to failure again, if the board was repaired, this is why generally we replace the entire main Board, if there are any faults found, as in the long run,it will prove to be the best option.
To effect any repair one simply must have a service manual for your exact make and model, then at least you will have the wiring diagram and parts numbers, and troubleshooting steps.
Of course as usual it is my professional recommendation, to call an authorised service center and obtain a "Quote" for the repair.

Hello. This problem could well be that that breaker in your panel is faulty, or that the connections at the breaker are loose, or that the connections in the receptacle are loose, or that the connections at either end of the washing machine plug are loose. IF you are trained to check these things, it is best to have a qualified electrician check it out, for safety's sake. Joe

If this set is having the control panel which is electronic then it is possible that power supply unit if faulty which is a SMPS unit. Inthis case please check this link for help. Since the breaker is tripping it is confirmed that the front end of the power has a short. So use a multimeter to test , release the shorted component to confirm
