Hello everyone,
Some time ago, I turned here for advice and help with the problem of the sluggish piston in the brew group.
...that worked really well.
I repeated this again recently and it was successful again.
Thanks again for the help and instructions.
Now the same machine is giving me a completely new problem.
The machine switched itself on again and again at irregular intervals. Nothing actually happened that caused any damage, It was just annoying because it was often in the middle of the night.
I solved the problem by switching off the main switch on the back of the machine.
To use it in the morning, switch it on at the back, then the standby switch at the front and the coffee was ready after it had warmed up.
Now for the new problem, we did everything as described above.
After switching on at the back, the four red indicator lights B 11, B 12, B 13 and B 15 light up permanently after a short moment and nothing else works.
I cleaned the appliance as far as I could behind the front flap A 16 and also the brew group A 20.
The brew group also runs smoothly and everything is fine as far as I can tell.
The machine only starts up again and the indicator lights stay on...
What should I do?
...I'm looking forward to the answers...,
Reinhard
