10 Troubleshooting

83311002 1/2018-03 La

100-132

10.5 Operating problems

The following faults must only be rectified by qualified personnel:

Observation

Cause

Rectification

Oil pump makes severe mech-
anical noise

Oil pump sucks air

Ensure oil supply is tight

High vacuum in oil line

Clean filter
Check oil supply

Flame tube/air nozzle has heavy
soot deposit

Oil nozzle defective

Replace oil nozzle [ch. 9.10]

Nozzle distance incorrect

Check nozzle distance, adjust if
necessary [ch. 9.6]

Incorrect combustion air quantity

Adjust burner

Incorrect air outlet on mixing head

Check seat of light tube end piece

Combustion pulsating or burner
booming

Nozzle distance incorrect

Check nozzle distance, adjust if
necessary [ch. 9.6]

Wrong oil nozzle

Check nozzle type [ch. 7.4.1]

Capacity range of air nozzle exceeded

Check air nozzle [ch. 7.4.1]

CO content too high

Nozzle distance too big

Check nozzle distance, adjust if
necessary [ch. 9.6]

Stability problems

Nozzle distance incorrect

Check nozzle distance, adjust if
necessary [ch. 9.6]

Mechanical noises

Condensate drainage is not guaranteed

Check the condensate drain

Smell of flue gas

Siphon fill level insufficient

Fill siphon [ch. 5.3]

Hydraulic noise during DHE op-
eration

No DHW operation

Three way valve does not switch cor-
rectly

Install gravity brake from the supply to
DHW tank in the return line

The burner starts, runs as far as
operating phase

, switches off

and restarts

After 10 abortive starts the sys-
tem goes to lock out with

F47

Ignition faulty

Check the ignition unit and replace if
necessary

Service indicator flashes after
commissioning

Current combustion chamber pressures
have not been re-measured and stored.

Carry out commissioning using the
commissioning program (parameter

)
