Worcester Boiler B7 257 error code

My one-year-old Worcester boiler is displaying a B7 257 error code from last three days on the display board. According to the user guide, the problem is with PCB. Is it right? Please help



Yes Lynn, you are right. Here the problem lies directly with the boiler’s PCB i.e. printed circuit board. Therefore, whenever there is an issue with the PCB, your boiler will always malfunction. Moreover, this can lead to the heating coming off & on haphazardly or water/radiators not having the desired temperature. The best piece of advice is to call an emergency electrician & heating engineer for immediate help.
