Hi Luis, thanks for answering, I am going to change the resistance and you recommend me to change the Q7 ??? The resistances are 100 ohms?

Dear, the resistors are 10 ohms. Before replacing the triac, check its condition. Regards

Ok Luis I'm going to replace and raise the Q7 to check it

Hello people, I told you, I changed the resistors and it worked a few days and again it failed again, something I notice is that the washing machine works forced because a ruleman makes a lot of noise, can this be the cause of the resistance to burn?

Dear, if the washing machine works "forced", it will damage the engine, but not the plate. Now if you have low voltage, it will damage the plate and will work "forced" the motor. Regards

Hi Luis, how are you, thank you for responding, I tell you, yesterday I took out the plaque and again one of the resistances was desoldering, the temperature is so high that the tin is loosened and the resistance comes out, what can I do to make that do not happen, the rest of the components of the board nothing happened, I do not know how to solve this problem, I appreciate your help Luis and the colleagues to solve, thanks

Dear, tell you what is the resistance in question, to have a better picture. Do not forget to measure the grid voltage. Regards

Hi Luis, thanks for answering, the resistors are R38 and R42, the latter is the one that is dissolved by the high temperature, the mains voltage is 220 / 222v

Dear, before a similar problem, replace the 1.5 capacitor and the triac "Q7" solve the problem. Regards

Luis changed the resistances again and it worked, we are in contact, greetings and as always thank you very much
