Customer complaint: NOT WORKING, ERROR E92-10; STRAY ARM NOT WORKING; SHOWS MALFUNCTION ERROR;. Initial visit (Nov 12) — Mike S: Reported concern The customer reported a recurring error code related to spray arm rotation monitoring. Despite the error code, the dishwasher continues to clean effectively, and the spray arm has been observed rotating during operation. Assessment This issue has required previous service visits, during which replacing the control board and cleaning around the spray arm rotation sensor temporarily resolved the code. During current testing, spray arm rotation was confirmed functional upon opening the door, indicating the arm operates even though the rotation monitoring system continues to trigger an error. A review of manufacturer technical literature identified an applicable Bosch Technical Service Bulletin (TSB) addressing this specific symptom and error condition. Next steps Based on the diagnostic findings and the manufacturer bulletin, recommended repairs include replacing the spray arm rotation sensor housing and the power control drive assembly. It is recommended to verify part numbers against the TSB guidance prior to ordering components.
