Error Code Name

Causes and their solutions

RAM Failure,
backup battery capacity
reduced or dead

Turn ELB OFF, then back ON (reset) and confirm whether



Replace backup battery

If error cannot be cleared by ELB reset or battery
replacement, Contact original dealer of purchase

EEPROM Failure

Turn ELB OFF, then back ON (reset) and confirm whether
there is a change in data code on EEPROM.



Change data code on EEPROM.



Replace backup battery

Contact original dealer of purchase if this error cannot be
cleared after completing above items.

Door Open

Door is open.



NOT a malfunction.

“

” flashes in lower display, and heater/fan motor are
