8. Malfunction diagnosis
Fault Cause Remedy
1. Oil firing unit
Fault signal lamp is not lighting No voltage is present Check wiring
Boiler temperature control has not
been set correctly
Adjust properly
Fault signal lamp is lighting Oil firing unit set to malfunction Correct the fault
Oil firing unit is defective Exchange
Terminal socket wring is not correct Check wiring
Check oil pre-heater
Decode cause of malfunction through LED flashing diode Remedy of decoded malfunction
according to Chapter. 2.6 (only for Siemens LMO 14)
according to error diagnosis, point 2 ... 10
