British gas say to rewire, electrician says the wiring iss fine and there is no need to replace the wires.
Next visit will be britush gas tomorrow.
Then I'm on holiday for a week Sunday.
This has been one frustrating problem.
If resolved I will post the fault,
Sparky reckons the problem could be a faulty 3 way valve.
Removed the hive thermostat and installed the old thermostat.
With thermostat turn off the boiler has an orange light
Turn stat on . Boiler goes red
The 3 way myson valve buzzes too
Thoughts? Could the 3 way valve be a wiring...
Thank Andy
When the electrician is around we can check this again. I'm confident the connections are good though as I've check and started over a few times now.
All suggestions are appreciated
Hi
No burns marks on thr cable or hacksaw blade.
I have asked an electricIan from work to take a look as he is local to me. (Hopefully tonight)
Other than the nick in the blue wire all cables look perfect. I pulled them all out again last night for another look.
I was cutting using a hack saw blade so minimal vibration?
The BG engineer looked at the wiring and said something funny is going on and can quote a rewire. 3 hours at 90 per hour
It is so strange though as I have pulled the 3 cables out that go to that connector block. Only the one cable...
Hi thanks for these posts
I'm so confused
I only put a nick in the blue cable (red blue yellow earth cable)
I was using a hack saw
British gas has been round tonight. Changed the cassette, checked the internal fuse, changed the pump. He tells me to get a rewire as he can't figure out what...
Hi Stem
I will be calling the boiler engineers shortly.
One thing that I'm not sure about.
Is seems the fuse was blown from a small nick in the blue wire (return from pump), is this possible?
Thanks
I do wonder if this could have damaged a component on a circuit board or blew the pump somehow?
I would be great if nothing was damaged but I can't clear the lockout for some reason
