Bosch Slim D/W (SPS40C12GB/01) Burnt resistor on Module

[neon_3SP_glow]

Bosch Slim dish washer
Model: SPS40C12GB/01
9108 02422

The Module has a burnt Resistor located just North of the big Black Capacitor.

Any ideas How the Resistor is rated and where I could find a replacement? Willing to attempt a repair, its not definate that the module has corrupted itself.

Thanks all, have a nice day now.

chances are this is a fusible resistor where the power comes into the module. normally I expect about 50 ohms or so at about 3W (fusible)

this resistor feeds the mains into a rectifier and the dc voltage at about 325v appears on the big capacitor. This voltage is then used by the 7 leg chip (TYN264) to lower the voltage for the module to 12v or what ever . If this resistor has blown I would suggest the TNY chip has also
lots more examples of this failure in the sticky at the top of this forum

Thanks for the reply Dave.

Do you mean the ‘simple pcb repairs’ thread? I just scouted through it and didnt see anything similar? Maybe you mean another sticky?

Cheers.

no it is simple pcb thread

see page 4 entitled (Electrolux EWM1000 ) same fault as yours
