Look for flashing indicator lights when the washer refuses to start or stops during operation.

Treat the flashing pattern as an error indication, and correct the underlying failure the code points to.

Motor and user-interface related failures may present similarly across models.

Drive-related errors apply to models with a separate drive board, which is typical of TL and TR series washers.
