I don't think there will be a memory card on the circuit board. I think all the required memory will be in the microcontroller.
(The TMPM376FDFG according to the link to information I posted.) I have only briefly looked at this information and it seems there are two signals from the control board to the door lock. One to open it and one to close it. Do you know if the door lock is working ? Did you replace the door lock or just the door lock switch ?

I have only replaced the switch.And am testing outside of the machine.Not with the 2 bolts attached

 

Hi again.According to the pic of the board where do i have to measure the voltage?? Where are the wires of the door switch conector coming from?? Desperated need help.Regards

 

All of that information should be in the link to the download of the service manual that I provided in post #18. It seems to be a proper manufacturers manual. It contains a wiring diagram showing the wiring between components. It even has a schematic for the main board which will be a great help if the fault is on the main board. One thing I could not find in it was a picture of the door lock assembly.

Hi Jorge,
Page 50 of the manual shows CN6 & CN5 door lock wiring sockets
Can you bypass the door lock temporarily, just to get the machine working?
Do you have to translate these replies?

Good luck......

 

Thanks a lot guys for your help.Two hats i do understand what you guys writing me so o dont need the translator yet..Regards.
What about the noise filter??i inderstand that is a in out device.If the voltage in is 220v and the exit voltage is less coul be the problem.

 

Hi Jorge & twohats, I have just realised that he manual I found is the wrong one. I did a search on Google for wf106u4sawq schematic and showed WD106UHSA schematic. I did not notice it was not the model I asked Google to search for.
Sorry for the confusion. I have not been able to find the correct service manual.

I did the bypas but didnt work i think its because i dont have the neccesary voltage in the conector.

 

Yeah the transformer wrapped in green tape there is your problem you confirmed it by your measurement!

Hi did the test with another transformer same model and remains the problem.

I believe this site has free schematics give it a try.
