I have a Drean Cda 156 to repair, I did not drain ... when I brought it to the workshop and checked it, I also found that the drainage pump, the thermo actuator and the door lock did not work. Checking the platelet I found the corresponding triac broken ... I change it for a new one ... I checked the washing machine and found that the door lock was short ... then replace it with a new one. I put the plate and follow the same problem. Additional proof: I placed a new plate and everything works perfect. My question is, what would I need to change in the plate that does not work or what the problem may be? Thank you

Dear, whenever a repaired plate is replaced or installed, the block door and thermo actuator must be changed, which are the cause of the damage. When replacing the triac that controls these devices, the polarization resistances of the gate electrode should also be changed. regards

It's the Q3 triac that he manages that ... change it and go ...
