Buderus Error Code 6L Ionisation Probe +352 20 60 22 22 Webe
Buderus error code 6L (6L 229, 6L 517, 6L 548): ionisation probe fault. Cleaning possible? Buderus heating engineer Luxembourg 24/7.
Error code 6L (variants: 6L 229, 6L 517, 6L 548, 6L 561) indicates an ionisation probe fault on Buderus GB125 and GB132 boilers.
The ionisation probe is an electrode that sits in the flame to confirm combustion is active. If fouled or worn, it no longer detects the flame and the boiler shuts down for safety.
In some cases, cleaning with fine abrasive paper is sufficient. If the probe is corroded, replacement is needed — a common part. On-site quote provided.

FAQ
Can I clean the Buderus ionisation probe myself?
Technically yes, with fine abrasive paper to remove oxide deposits. But it requires partially disassembling the burner. If you're not comfortable, call a professional.
What's the difference between 6L 229 and 6L 548?
The internal code (229, 517, 548, 561) specifies the exact nature of the probe or wiring fault, but the solution is similar: cleaning or replacing the ionisation probe.
How much does a Buderus ionisation probe cost?
Common part. The price is assessed on site. A quote is provided before any work.
Can code 6L return after replacement?
If code 6L returns after probe replacement, the problem is likely in the wiring or combustion quality (insufficient gas pressure). A full diagnosis is then needed.
