Potterton Promax system HE plus keeps ‘running’

Postby Corporaterat » Wed Jan 13, 2021 8:55 am

Potterton Promax system HE plus keeps ‘running’ After the boiler has stopped heating. No error codes. No issues with hot water or heating. It just continues to ‘pump’ or run at the boiler itself. Tried reset. It’ll go off for a while then May run again. Any ideas?
