Just purchased 2nd hand Miele novotronic w310. Does machine automatically stop? Cycle ends, anti crease light on and machine just tumbles clothes makes odd noise, then tumbles again. Is the normal?

Flashing rinse light is a drive fault. No motor action. If it's an earlier model it would be the motor brushes. Later model will be the electronic which controls the motor.

Main wash light flashing is a heating fault. You either have a faulty temp sensor (NTC) or the pressure chamber has blocked and the heater element has popped.

K5? which pipe is that..let's assume you have pressure to the back of the unit, yes? then you have a valve sticking or something obstructing the channels inside that unit..

does this work regardless of temperature setting.

Could be a coin.
Use to have large coin when i was young and forgot remove from my jeans. So mum made me repair that every time. In that case filter clean, but coin bloking filter inlet.
Not necesarily coin in your case.
never buy these deals over Ebay my advice.
If you have the machine already then this is first to look for.
