Hi Gary
The brace/clamp is fastened with a thumbscrew which should come off without too much trouble. The impeller on mine had ripped from a stick pin. Still unrepaired and gravity drained.
Another one delivered here had a drain port detergent build up, but since you take such good care of your machines, doubtful of that cause, though a much easier fix. Wish you luck. Last I heard, the impeller was still available from large appliance parts stores.
