Bosch dishwasher No SGS43E02GB there was a strong smell of burning `PCB` board then the mains fuse was blown. replaced fuse to try and identify source of fault, machine is completely inoperative. is a service manual/workshop manual available

Based on your description, it sounds like there was a short circuit in the dishwasher which caused the fuse to blow and the burning smell. It is possible that the burnt connection you are seeing is related to the short circuit.
If you have experience with electrical repairs, you can try to identify and replace the burnt connection. However, if you are not comfortable with electrical work, it is recommended that you seek the assistance of a qualified technician to avoid any potential safety hazards.
In any case, before attempting any repairs, make sure that the dishwasher is disconnected from the power source and that all safety precautions are taken.

Had the same issue with a 903sa. Strong burning smell. Continued to run for a while then just died. Opened the control panel (4 screws holding the plastic part at the top of the door on - open the door to access).

Mains feed into the controller was totally fried. Case was all melted. Very nasty. There was nothing obvious on the Board other than a mains resistor that looked like it had been pretty hot at some stage. The three pin mains connector (at least I think it was 3 pins) was just a big, charred bit of goop.

it sounds like you have a power surge from one of the components on the main pcb/circuit board, if you can get hold of mains tester or know someone with one you can set the cycle then test each component as it goes through its cycle and the problem part will show on the metre, the down side to this sort of problem is its usually as expensive for most of the part as it is for a new pcb, hope this helps

Hello,

one or more components is burnt on the board of the unit. Or there might be a bridge of wire which is causing the smell....

Hello,

Welcome to FixYa. Based on your description ( specifically the smell ) I would suspect the control board is faulty.

However, these faults are usually easy to identify and again based on the fact that none of the indicators are working I`d rule those both out quite quickly.

The control board for those is not that expensive, relative to the cost of the machine at least... typically around $250. The original Asko part is, 8801286.

I would be one of a minority I think in saying these are great dishwashers, but typically they are doomed from day one due to improper installation and improper service by unqualified techs & "handymen".

If you decide to try to inspect or repair just remember please...

**Turn off the power at your main breaker before attempting any service...safety first**

Let me know if I can assist you further. Thank you for choosing FixYa today.

Please take a second to accept and rate the info I provided for you here today.

Good luck.

Sorry I can't solve your problem. I think the main fuse on mine is blown too. Can you tell me where it is located?

There is probably a short circuit on the appliance, or a component such as the motor or timer/control board is defective. Contact an appliance service company.

Start at the main power connections underneath. Then look in the control board area next. Eric

Bosch dishwashers often have bad circuit boards.

Just so you know. Bosch has a 5 year warranty on any printed circuit board (excluding labor) so you pay only for labor charges. They have a 2 year warranty (again excluding labor) on the entire dishwasher. I am leaving a copy of my owners manuals warranty information I hope this helps.
