If there's water underneath the machine, check drainage pump. Most likely gasket or simmering. If necessary replace pump (about $45,00).

Check if the drain hose is blocked. Check the wires aren't loose on the drain pump. If all that's ok you will need to replace the drain pump.

Hi just wondering if you got your problem with your miele sorted out yet as mine has done the exact same thing. Rinse light flashing rapidly and cycle stoped. Have cleaned the filter and re started but no joy.Any luck?

No.
At the beginning of every cycle water enters appliance via top of door seal this is connected to the inlet water supply

I would run a few cycles with just water added to the bleach dispenser, clean it out, and see if that helps.

The conditioner part of the drawer is still blocked. Take the drawer out and turn it over, on the bottom of the drawer you will see what looks like a blanking plug, it's about 1" or so in diameter. Carefully, prise off the plug with a flat blade screwdriver, and you will find lots of sludge blocking the syphon path. Remove syphon and and run hot water through until you can see daylight through the syphon hole where you just removed that blanking plug. Re-fit blanking plug giving it a little tap home. This should sort it.

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.
