Oko Lavamat 74620 update

[lavame]

This machine seems hexed!
It would run normally for a while.
Then, after longer periods of not using it, it would just not start, for a few minutes, sometimes a few hours. Once, it woke me up when it started in the early morning at least 12 hours after pressing the start button. Lately, it fills then takes hours to start rotating.
What could be causing this?
Faulty door locking?
Today, befor it eventually started, it flashed and threw a code- Cd.

CD is supposed to be a faulty door interlock.

Could be: a poor soldering relay joint on the bottom pcboard. The line of thinking goes something like this: the motor relay soldered joint is poor ( if you have a look AND IF it is indeed that you will visually see it ) = the door lock is wired through the pcb via the motor = no drum action = no go = might go. A similar problem happens when the motor brushes are nearly worn out and the motor is running on brush dust; it might be that AND
at the backside of the pcb and so if you see a poor soldered spot resolder it. Note if the motor brushes are worn out a new set appears to be unavailable (?) but usually a pair of Hotpoint fhp “L” type brushes should do the job but check first.

Ditto to that conclusion 😉

I did once take out the circuit board, the top one, and checked all solder joints.
The motor either runs or does not start- there are no symptoms typical with worn brushes.
I shall check the bottom circuit board and the relay connections.
