Hi.
Does anyone know if an unlabelled red light on the front switch board of the potterton puma 80 means my pump is kaputen?
 
If it's on all the time and your boiler's overheating and your radiators are getting hot, your "DHW Flow Switch" is stuck on. Do a search on that term.
 
thanks guys, most informative as per
the light has extinguished after my re-igniting the pilot and switching the CH to constant.
the bizarre world of potterton!
