Step-by-Step Diagnostic Procedure
Identify which Xc-series controller your machine has FIRST (Xc1004, Xc2003 or Xc4004 — it is named on the controller face or in the machine documentation). The same alarm number can mean different things on different controllers, so the controller identity is part of the diagnosis.
On Xc1004: alarm 7180 = Ash load
