Yes, pump never stops. Diaphram pin retracting and working fine. boiler does not seem to be cycling. hot water working fine on demand.
Thanks for replys.
Many thanks.
Didn't want to take apart without replacement as bottom R/H screw is near-on impossible to get at. Allready checked saddle switch and boiler fires.
So I'll take your advice and strip it down, I had a Giannoni diaphram on van, but valve looked smaller (I Know Spec-savers...
Hi, Can anyone inform me were I can get a Diaphram for a Ravenheat White Star LS 100.. I've been informed I need the valve. This is not the 8 screw Gianoni type that I've come across before, but a smaller 4 screw type. Still a pig to get at.
Hi, Has anyone come across a Ravenheat LS80 Diaphragm repair kit, or is it a new shunter valve needed (As Ravenheat has informed me!!) Please help.
Has anyone come across a LS80 before??? Apparently its only 4yrs old. I'm sure it's just diaphragm, but haven't removed valve yet!
Thanks in...
Heating okay. No hot water, boiler fires and cycles, heating F & R pipes remain cold, water pressure ok. Is problem secondary exchanger or diverter? How does one test!!!!
