Hello,
Just had a Vaillant installed 2 weeks ago and all was working fine until it displayed a "spanner" symbol. Now it wont work with either heating or DHW.
The service code displayed on the lcd display shows S.39 which, according to the manual is 'Burner off contact has triggered'.
No fault code at all, but boiler wont work. I've tried a reset, and power off/on.
Obviously it's still under warranty, but why would it stop working with just a service code ? And how do i clear the service code ?
Many thanks.
