Drean unicomand 116 washing machine does not cut water

Hello people from the forum ... I am with a Drean washing machine that does not cut off the water intake ... check the pressure switch and it is normal ... I presume that the loading triac is short ... starts charging in the off position. another detail .. the microprocessor could have been damaged? The blocapuerta ??

Hello, when you load water as soon as it is plugged in, it is because one of the triacs that feed the solenoid valves is damaged, check the Q1 and Q2, together with their associated resistance, greetings.

Thanks Alturasbal ... I think it's like that ... but the only drawback is that I have no reference to what triac to replace ... the ones I have are not identified ... I have two types ... TIC226D .. and 97 A8 ... which one do you think is going ???

In addition to the triacs ... supposes that the microprocessor could have been damaged .... how do I prove it ??? Thank you!!!

I don't know how to test the mic, the triac Q3 is equal to Q1 and Q2.

Dear, first check the "Q1", "Q2" triacs and determine which of the valves is letting the water through. Leave the mic quiet. If the triacs are good and the resistors associated with the Gate electrode are also good, then it is a problem with the microphone and you must replace the board, as it does not repair or change. Regarding the replacement of the triac, it depends on the version of the plate. Anyway I think the Tic226D is very big for this case. Cheers

Thanks Luis ... I'm going to try the triac ... with a lamp

Hello people!!! I already changed the triac and their associated resistances ... some were open ... when I tried them I commented ... arms!

Well ... try the repaired board and it works ok. The only thing I observe is that it cuts the water to the limit of filling the drum ... will it be normal like this ???

Dear, this is a machine with a very basic design and the difference between half load and full load is similar. They always carry almost to the edge of the basket. Cheers
