yep inhib in on satis outcome

o.k thanks for input. Have you experienced the same faults prior to changing these? Thinking of full system drain down as don`t want leaking valves for boiler shut off and boiler situ is a pain. :x

beerlover, I think I see what you mean. The Parts list only really shows the left hand brass part, but there is also a fixed part on the R/hand side. Why is it crucial one at a time? What has been the problem side in your experience? comments welcome

Also Agile would pressure diff micro switch not operate if pump had failed?

Agile, Turned impeller by hand earlier. Selector alters speed o.k. Have not actually split apart, but checked diverter valve and it is definately only protruding about 2/3mm and not able to manually press down or retuning to C/H position as fault finder specifies it should. Assuming therefore...

Where the same faults being reported on the ones you have changed? Can a spring replacement be possible? Do you think if may have just stuck with no C/H being used ove r the summer? Give me some hope I am hoping to free this! :roll:

Yes not much room on the left. £80 :oops: Have you changed one? Can they be freed off? How far does that pin normally protrude? The fault finder talks as if it normally can be pushed across by hand easily? regards

Back to this one guys? I would appreciate the experts opinion with regards the following Fault persists. Pump is working o.k. Boiler still shuts down after 1 min when C/H selected with an increased water temp from D/H/W for a short time afterwards ( assuming the small C/H fire up is causing...

Yeh Thanks I`ll play that one by ear. i.e. see if it feels tight at first. I`ll report back with results when been back there.

It does sound a possibility Mick. Maybe I`ve been kidded by the pump noise change when the speed adjuster is changed! Nex visit = Pump bleed screw off and try and see if impeller can be spun with screwdriver!

It is very hot around the pump area though!

does not go to lockout and does not require a reset. It just shuts down after about 1 min of burner operation and then does the same again eventually after it has cooled down.

System and pump bled earlier, problem persists? Suggestions welcome!

All that I do know is as was when last working. I am there a lot. Do you think just a settlement of air could possibly cause this? :cry:

Yes they are Mick, It was working fine before warm weather came...........but I have just thought....maybe an air lock has occured due to staticness over summer with subsequent C/h call moving it through system. Thoughts? I shall make that the first port of call when I get down there!

It`s been 37 mins guys and no ponters?

Hi all, Looking for some pointers? Daughter has decided to try heating after months of just D/h/w. Start up procedures appear to go all o.k. with no lock outs and boiler fires up but only for 1 min and then cuts off! D/h/w call has been mediocre for months( luke warm ). Whilst c/h was on it (...

Anyone changed the diverter valve with needle? Drain down required? Cheers

Hi, I am aware that no drain down is required to disconnect Diverter switch for test, but is a drain down required if removal of Diverter valve with pin in required? Cheers!

Thanks for reply. Will have to do over the next few days when at house. But will give feedback when tested. Reading fault finder, removal of Diverter switch and manually pushing spindle in Diverter valve ( if it gives hot water on push in and C/h on release out would prove Diverter switch motor...
