No power to boiler

[motobroox]

Hi, I looking for some help please. My boiler stopped working a couple of days ago. There's L N E SwL coming into the boiler. When call for heat is given, the SwL comes from 40v to 250v, but the other live stays about 40v. The feed into the clock is ok at 250v, but there no voltage going into the pump at CFH. Is the clock bust?

Just a side note on the boiler, it's not spurred downstairs, so I'm guessing it's getting it's voltage from the clock switch?

TIA

No good guessing with gas or electricity motobroox, may I suggest you get a specialist in to sort it out safely for you.:yes:

I had a specialist to do a repair on my boiler. He switched off a nearby switch without asking me what it was for, he just guessed. In fact, it was for my washing machine.

The result - - - he had a nasty full mains voltage electric shock! Not fatal though, it just caused lots of swearing.

A specialist what though, tiler, plasterer, brickie, 6ww wonder (or even some time served that I know) spark?

It certainly wasn't a competent heating engineer!

not a specialist if safe isolation is not known lol.

Between which conductors are you getting voltage? Did you test L to E, L to N? Bear in mind you will get voltage between live and anything conductive with a return path to earth. You may have lost a neutral for whatever reason. More likely though is the boiler or programmer not switching as it should. What type of heating system do you have?

I would say you probably need an electrician rather than gas engineer but anyone who doesn't test for safe isolation deserves the shock they get.

Dare I mention that it was a GSR employed by a nationally-known company referred to by 2 initials, the first one the same as a striped insect that stings and makes honey. The second is what you say to a horse to make it walk.
