Hi, please help.
Here’s the washing machine.

Unfortunately, there are no captions, so the symbols are not entirely clear. Can you provide a link to an online page that explains this cyclogram? I want to test all the electrical circuits.
Or could you explain it in the context of this chat?
As I wrote above, I couldn’t find an explanation of the cyclogram anywhere. Therefore, I assumed that the thick vertical black lines to the right of the program number indicate which switch contact is closed. The switch numbers are at the bottom (01, 1, 2, …, 13 16). It’s unclear why the data for switches 15 12, 16 13, 14 11, and 17 are listed in a separate table below. Moreover, they don’t correlate with the program number, but with the rotation angle (180 – 0 degrees, 360 – 0 degrees).Can someone explain?
there are 2 sections to the timer
the back cams move all the time, they do things like reverse the motor. and start and stop the motor. that will probably be the lower diagram
then there is the main cam switch which move one click every now and then. that does every thing else . valves. heater pump etc

Ah, so that’s how it is, thanks for the explanation. Now it makes sense, I thought it had to do with the water temperature and drying time controls:
But then the question arises: how do I calculate the number of degrees of rotation for the selected program on the timer? For example, I select program 17 (Delicate Spin), since it involves drum rotation without any additional options:
Yes, the drum doesn’t spin. Water drains and fills, but there’s no wash or spin. The motor runs when I apply the opening voltage to the thyristor gate.
Here, I’ve marked in green what’s definitely correct on the cycle diagram for program 17. And accordingly, on the electrical diagram..jpg)
But this bottom table with degrees is not entirely clear to me.
Over complicating the issue! I assume you have checked the motor brushes? This is the first place to look. If not the suspect faulty motor control module or timer?
On some older appliances blocked pressure chamber will affect no spin, usually this will cause overfilling as well?Steven wrote:On some older appliances blocked pressure chamber will affect no spin, usually this will cause overfilling as well?
Incidentally, I once observed an overflow at the very beginning. Water just kept pouring in. I had to unplug it. Before that, the washing machine had been sitting unused for a year. After blowing out the sensor, the problem disappeared. But the motor still wouldn’t start.
well the most likely fault is the motor board. if you just triggered the triac does not mean board is ok
did you check motor tacho. on some boards motor wont run with open circuit tacho
next is the reversing contacts at the rear of the timer and the contact that activates the module to start and stop motor
if all those are ok then its the module control contacts

Although I still don’t have an answer to the question about the switches in the bottom table of the cycle diagram, this is presumably what the complete diagram looks like when selecting program 17 (Delicate spin):
you are going deeper than we would as engineers
from the diagram you should be able to work out the trigger wires for the module as a way of testing it
there will be one trigger wire to start and stop motor
the other wires going to the module set speed wash , distribute and spinmost of the time problems like this are the motor control board
