MDB9601 suddenly stopped working, and instead started humming loudly. When I open the door, a loud grinding noise can be heard (from where i assume the pump is at the bottom of the unit) stopping and grinding slowly to a halt.
All on-line diagnostics seem to indicate that something is caught in the impeller somewhere but all of them report that their units fill and then start humming when something is caught in the impeller. Here, if there is something jammed into the impeller, where is the grinding sound coming from to grind to a halt?
Does anyone know anything about these units and have any idea whether this is something caught in the impeller preventing the water filling or something stopping the water filling preventing the unit working with no water input? (Nothing has operated to prevent the water coming in such as a water shut-off, and the water supply is shared with the washing machine which still works)
