DMR57 Wiring Diagram
Included in the DMR57 and 77 is an auto wash cycle which will wash the contents
of the machine until the internal water reaches a certain level of clarity. The sensor
which determines this is the "Turbidity" sensor. If this sensor fails a possible
symptom might be very long wash and rinse cycles if the auto wash mode is used.
A check if this is the case might be to place the washer into a time determined cycle
such as normal wash.
