Have a Valliant Boiler eco 426 with status code S46 - boiler quiet & taking ages to heat & costing more to run. Only noticed when had bill through! It was high despite less usage. If we switch boiler off & on then no error/status codes & works fine.
Wondering if a service would sort as the status code s46 says comfort protection minimum load loss of flame or whether some sensor needs replacement 🤷🏻♀️
Thanks for any advice
