Gas, power, demand and water is there at least I'm sure that water is there because the pump in the airing cupboard sounds like it's pumping water and, in fact I never shut the system down I just turned the programmer to "off" the other day as it was hot and I didn't want it kicking in come the morning!
The model is either a 30e, 40e, 50e, 60e or 80e the manual covers all and I can't be arsed to go down while writing this : I'm starting to be convinced that something has gone in the boiler itself such as the Overheat thermostat and was wondering if anyone here can offer up some suggestions before I call in am engineer? I've tried the manual reset button but that hasn't had any effect although it doesn't seem to have a satisfying click to the button when pushed Appreciate any pointers.
Could I have trapped air in the system somehow as the pipes and water tank do gurgle when I switch it on? These boilers operate with positive air pressure. Make sure the case is fitting properly to prevent air leaks. Only 5 years late. Joined: 3 Sep Country:. Select the supplier or trade you require, enter your location to begin your search.

This is a long shot but I did once come across a situation with a profile where someone had rewired the boiler internally because he couldn't work out how to correct his faulty exteral wiring. That coupled with some external wiring error would give you this result.
I know much better plumbers than I who are the most appalling electricians. Profiles always used to have a colour coded wiring diagram on the inside of the undertray. Plumber has checked permanent live is there. Another plumber verified it. Also the fact the pump overides when central heating shuts down would suggest something is in place? No I think you would be wasting your money.
This has all the hallmarks of a wiring fault. I would like to know under what conditions the permanent live was checked. It is only of any value if the programmer is disconnected at the time - hence my suggestion that it be unclipped from the wall. What part of the world are you in? I noticed something odd the other day. If u switch the pump down from 3 to 2 then the boiler resets whilst heating within a few hours.
I dont think its pulling the water away quick enuff. Also the plinth heater in kitchen will only come on intermittently. Could my pump be the issue? It did have a problem of too much air passing thru it for ages due to a piping issue thats been fixed.
If the pump was the problem I would expect the heating to cause the lockout rather than the hot water. Still it won't hurt to take the top off and have a look!
Well the boiler is now behaving itself we: changed pump over run stat and nothing happened. Otherwise you have to send old board in to get the deal. The other parts it can be are about 15pounds each and are: Boiler stat overheat stat pump overrun You can pick up all the parts cheaper yourself, i use sabre systems on ebay, again just type in the part numbers.
Then get a corgi guy to change all of them. Its honestly cheaper in the longrun than getting a corgi guy back three times.
