3 FAULT DIAGNOSTICS
All errors of the Power Board and the Clock Board are displayed using the seven
segment digits on the Clock Board.
There are two types of fault codes,
A – Alert codes:
These are customer errors which can be solved by generally letting
the product cool down, or powering it off then on at the wall. These codes will show
