no power to boiler

[mrmack]

evening all, I have a heat line s24 combi boiler, worked fine this morning, went to turn it on this evening and there was no power to it
any suggestions please, I have checked the plug and the socket

 

[Agile]

So exactly how did you check the plug and socket?

Tony

 

[mrmack]

I plugged something else into the socket and a new fuse in the plug

 

[Agile]

The next test would be to see if power is reaching the boiler!

What value of new fuse? How do you know it worked?

Tony

 

[mrmack]

after reading your comment I have just tried a fuse out of something I know works, still no power

The next test would be to see if power is reaching the boiler!

What value of new fuse?

Tony

 

[mrmack]

What value of new fuse?
sorry, I don't understand this

 

[mrmack]

3 amp ?

 

[Agile]

Well I was asking you! It should be three amp but is it?

Next is to see if power arriving at boiler

 

[mrmack]

I tried 3 different 3 amp fuses
I'm going to try to get a mate down tomorrow to try and find out where the power problem is, with one of them tools that do that. In case you haven't noticed, I'm not good with electrics.
If we find the problem, could you offer advice as to why it broke?
It has an intermittent leak and I found out tonight that it is coming from the connection on the 'three-port valve', it might not leak for months then drips constantly
Also, it cuts out saying the pressure is low but when I top it up for less than a second it jumps right up. When the boiler is off, the pressure is just above '1', but when it kicks in it is nearer 2 1/2?
thanks for your patience Tony

Your pcb fuse is blown.

Your diverter valve motor is burnt out from water entry.

Your diverter valve gland is leaking.

Your system water is dirty.

Your expansion vessel is deflated or faulty.

 

[mrmack]

big job then? lol

 

[mrmack]

how would the system water get 'dirty'?

 

[mrmack]

are they possible faults or all different ones?

 

[Agile]

Those are the faults that you have.

Water dirty because system not cleaned when boiler installed.

I would charge £132 in local area but excluding any water treatment apart from a quick dynamic flush.
