8. Troubleshooting

Diagnosis
1. Oil firing unit
Error signal lamp is not on
Error signal lamp on
2. Motor
Motor does not start
Loud noise caused by running motor
3. Ignition
No generation of ignition sparks
Weak ignition spark
4. Oil pump
Inconsistent oil pressure, loud noise from
operating oil pump, no oil pressure is built up Oil supply not according to the specifications
5. Magnetic valve
Magnetic valve does not open
6. Flame monitoring
Fault shut-down without flame generation
Fault shut-down with flame generation
7. Nozzle
Inconsistent atomisation, high CO and
soot emissions
8. Baffle plate
Baffle plate / burner pipe very contaminated
9. Blower
Blower delivers not enough air
Loud noise during blower operation
