Fault or error codes

Potterton boilers can give various error codes every time they are restarted but most frequently, the E168 code. Sometimes a boiler may start and run for several minutes and then stall, displaying error code E160 and then error E168 once again.

The underlying fault may not be necessarily remedied by replacing the PCB. Instead, the entire system must be checked to confirm the fault codes and diagnose the actual error before the correct repair may be carried out.

Combi Gold HE A / Combi Promax HE Plus / Promax System HE Plus

E20, E28, E50, E110, E119, E125, E130, E131, E133, E156, E160

Please Note: The above error codes all refer to different problems with the boiler and you will need to call an qualified and experienced Gas Safe Potterton service engineer, such as BBS Plumbing and Heating, for further advice.
