Question about Miele 24 in. G646SC Plus Free-Standing Dishwasher
Miele g646 sc plus -3 dishwasher stops after 10 minutes inlet/drain light flashing have checked all filters are clean checked discharge hose and water is being pumped freely when running dishwater tablet is still whole in its container
I had the same problem on a 5 year old model. It was the main pump leaking from a perished seal causing the water protection microswitch to trip. This gives the symptoms you describe exactly. Parts cost from Miele was about £60 for a new seal. Fairly easy to fit.

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.
If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
Replace if defective (note: uncommon problem).

Tips for a great answer:
Dec 27, 2014 | Miele Dishwashers
check if the drain hose is not clogged and try to clean it as it can be that
the hose is clogged and the water is not draining properly. After that check if
the drain pump filter is fine and not clogged, try to clean that as well. After
this check the metal filter, impeller cover and the air gap unit. After checking this you can
reset the error as follows: turn the rotary selector switch to "Stop/End" or
press the "Start/Stop" switch for approx. 5 secs. Then switch the
appliance off and then back on again. Hope
this helps...please post back for further assistance.
