Miele Washing Machine Drain fault - multiple fixes

Miele Drain Fault
I’m not a washing machine repair technician. This is just how I have found out to take the machine apart.
So many have found this useful - I would be very grateful if all could subscribe - thanks for considering.
I have previously found lots of gunge in the pipes shown but it’s had another drain fault today.
Many of the processes are the same on lots of Miele machines.
Tools needed:
T20 and T30 tork (star) bits or drivers
Flat blade screw driver
Narrow nosed pliers
I used a radiator brush and bottle/pipe brushes to clean out the various pipes.
I use one of these boroscopes for lots of uses.

Addendum....
Our issue came back 3 weeks later, I still suspect that it's a gunged up pressure chamber (shown at the end of my video), my wife put some washing machine cleaner through the machine and it seems to be working OK since. Perhaps that was all it needed - however, may be a cheap and easy way for others to try fixing their machines first. It may save cleaning all the pipes manually like I did???

Addendum 2!!
The issue came back again a year later. I stripped the machine again and all was still very clean. I watched the failure when it happened and could feel the drain motor running by touching the filter flap at the front. But no water was draining even into a bucket. I replaced the motor with a compatible for £29 on eBay. SWMBO very happy again now. I am a hero again.

Possibly the motor was struggling at the start of this journey and cleaning everything gave it enough of a chance to get the water out????
