miele Miele novotronic w 807

[des18]

I have a Miele novotronic W807 (20 years without problem) yesterday started to make me this: Starts washing, draws water, it starts the main wash which takes too long (almost double time than ago) and when it's to go to the next step (rinse) crashes and then begins flashing the light of main wash(hauptwasche). https://www.youtube.com/watch?v=RWdLHmf ... e=youtu.be
1. If i leave it so, the light blinks and then after half an hour, the machine proceeds to the next step (rinse) lamp lights for rinsing, but the light of the main wash keeps flashing and the machine completes normally all subsequent stages (rinsing, wringing, emptying).
2. If I close the laundry once stuck the light of the main wash, reopen it and go to the next steps manually, the light unstuck, and the machine works normally.
Checked the filter, drain pump, pressure switch show all ok. Cleaned and all tubes but the problem remains.
Thanks for any help.

Technical information on Miele error codes is not easily available. I definitely don't have any technical information on non UK models. If the issue is only on wash and rinses and spins work OK you would have to first suspect a possible heating fault.

Thanks for your fast reply. Everything looks that it works good (except the flashing light of main wash(hauptwasche)). The truth is that 3-4 times, the washing machine stopped working  during the washing, and begins flashing the red light (pc Zu-Ablauf prufen). Then i close the laundry, reopen it and go to the next steps manually and the machine works normally.
