Hi all
I've a Ravenheat HE85T combi boiler which is also similar to CSI85.
WHen I put it ON for CH, the boiler comes on and then goes off. It carries on this cycle every 5-10 seconds, so I've turned it into DHW mode only (CH off).
DHW is running absolutely fine.
WHat could be the issue? I replaced both DHW and CH thermistors in Jan 08 when I had an intermittent DHW issue.
(The CH thermistor is a dry clip on type, the part number is 0007son11010/0 and more expensive than the DHW one which is a wet type with part number 0007TER05005/0)
Thanks in advance....
