Faulty Wiring and/or defective "Core" Control Board.
Making reference to the above resuming table of the available Error Codes, we like to remind
the importance of the perfect continuity of the electric wiring and of the related connectors,
when dealing with electronic controls of the "Core" family. This is both true for the contacts on
the Control Board then for the corresponding contacts on the controlled peripherals (Program's
Selector, Display Board, etc.)
A partial oxidation of some connector's contacts on the "Core" Control Board (or on the
connected peripherals, such as the Program's Selector and the Door Lock Safety Device),
could generate the displaying of a peripheral related Error Code, even being the involved
peripheral in perfect conditions.
Therefore, we suggest to carefully check the related wiring, before any replacement of the
"Core" Control Board and before replacing any of the related peripherals.
A valid check of the wiring can be performed by removing the connectors from their location
(both on the Control Board then on the related Peripheral) and by spraying inside the same
connectors a small amount of Contact Cleaner liquid. Then, re-fit the connector in position and
re-start the Auto-test routine, to see if the Error Warning is displayed again.
Best regards.
