MDB9750BWB10 Maytag Dishwasher - Instructions

Routine repair. There are videos on the net that show exactly how to replace the filter unit. However, when you order the filter, order a replacement pump impeller. The impeller must be removed to remove the filter on this model. The impeller was stuck on the shaft, and I had to destroy it with the side cutter pliers to get it off. Before putting the new one on, clean the pump shaft thoroughly and lube the shaft with silicon lube or vaseline jelly. Clean the bottom of the water pan thoroughly, then reassemble. Then pour one cup of vinegar in the bottom of the dishwasher and run it with no dishes. This will clean the inside of the dishwasher.
