how to fix my mw 512?

Manually empty as much water as possible ( use a small jug or similar) Turn power off at the wall socket. Pull machine forward away from the wall then tip it back against the wall as far as possible. Look under the front right corner and locate the pump. It will have the drain hose connected to it and has a plastic fan blade at the bottom. Try spinning the fan part forward & backward & see if it comes free & spins easily. If it does, stand machine upright & put on spin & see if it drains. If it stops & hums again then the pump will have to be taken out to clear the obstruction.
