We cleaned every part drain and tube with no luck.
Still water left in bottom

Ellen butler, May 2015

There may be some crud - debris - lemon pip jamming the pump's impeller.

You can get to the impeller from inside the cabinet - take out all the filters and right at the very bottom will be a single Torx screw holding the cover on.

Tweezers will help to remove the debris.

Of course this may not be the cause..., May 2015
