Miele G646SC flashing Inlet/Drain light?

Possible the impellor in the wash pump is clogged with debris. The machine normally fills to a set level then when the wash pump comes on and sprays the water around the level drops so the inlet valve opens a second time to refill. If your impellor is clogged the water level does not drop enough to bring on the inlet valve for a second time,the diagnostic picks up the fact the valve didn't open again so says inlet fault. if not this it could be motor running slow,bearing problem or motor capacitor faulty cheers
