Not been to this yet but customer says rinse light starts to flash shortly after starting to wash looked in known error codes but no match anyone have any ideas on this
Rinse led flashing means no motor action, i’d start by checking the motor brushes, back plate that houses brushes comes off motor.
If the motor is o.k & loom/connections are o.k then i’d think about getting a p.c.b.
There should be a schematic diagram in all Miele appliances that will allow you to check/trace cabling from p.c.b to motor.
