Thanks Rojaca, your diagnosis regarding the diverter valve on the boiler sticking open appears to be the case. I followed your instruction and it was as you said.
Thanks again!.
Thank you so much for taking time out to reply to my problem. I will try what you recommended and post a reply on here if what you suggested works.
Much appreciated!.
when i turned it to off as you suggested the light stayed on and stopped flashing as before. Would that suggest something other than the diaphram? i really appreciate your help by the way.
Hi! i'm new on here and need advice urgently. The green hot water mode is flashing on the boiler yet the radiators seem ok?. But the upstairs shower runs tepid now as does the taps?. Can anyone shed any light as i need a wash Lol!. Any advice with be appreciated.
