The thing is showing a code of 70 and 71. What is that?
Answer Hello John. CENTRAL CONTROL UNIT HEARTBEAT FAILURE OR USER INTERFACE HEARTBEAT FAILURE. If a Central Control Unit Heartbeat Failure is displayed, no communication
is detected from the Central Control Unit (CCU) to the User Interface. Possible Causes/Procedure
Check for continuity of the User Interface harness.
Check wire harness connections to the User Interface and the CCU.
Replace User Interface if drum is rotating.
Replace Central Control Unit if drum is not moving.
