This dishwasher signals an error code by flashing the Clean light in a pattern unique to the error. The light first flashes the Function code, pauses for 2 seconds, and then flashes the Problem code. For example, 6 flashes followed by 1 flash (6-1) means “Inlet Water” function, “Low Water/Air in Pump” problem.

After a 5-second pause, the light repeats the pattern. The control console is disabled when an error code is flashing.
