Rank: Member Groups: Registered Joined: 3/14/2008(UTC) Posts: 1		The Circulation Pump Does Not Run After The Drain Pump Operation And Tub Water Fill, It Just Emits A Hum. A Jump Start By Spinning The Motor Fan, After Removal Of The Right Side Panel, Did Not Help Because The Pump Impeller And Motor Rotor Did Not Spin Freely. After Several Turns, With The Power Off, It Freed Up But Would Only Operate For A Minute Or So. The Motor Was Removed And The Pump Impeller And Fan End Bearing Looked To In Good Shape. The Pump End Bearing Was Seized Into The Die Cast Housing And Could Not Be Removed , But The Visible End Of The Bearing Showed Some Distress In The Grease Seal, So Water And Detergent Probably Got By The Face Seal And Corroded The Ball Bearing. Are Replacement Bearings Available For This Motor, And Is There A Repair Manual Available For Bosch Units?

If the motor bearing is damaged, you have to replace the whole circulation pump assembly. Unfortunately Bosch kept all repair manuals as a top secret. They are available for an authorized servicers only. - The part number for the circulation pump is AP2826384 Here are the breakdown diagrams for the Bosch dishwasher Model SHU9922 UC/12 (FD 8003-) Gene.
