Heatline Boiler - no power, blown fuses?? Help please

[JoseGaf]

Firstly apologies as I'm a complete novice to boilers....the things not working hence I'm having to learn!
Came home from honeymoon last week to find the boiler wasn't on, no power. Checked the power feed to the boiler and this was fine as was the 3Amp fuse. Oven the unit where the power cable fed to and found 2 small 2 Amp glass fuses blown. I replaced these and everything seemed to work again.....later that day for no obvious reason they blew again, and then again!
Only other problem that may be a contributing factor is that there is a water leak which keeps dropping the boiler BAR pressure, keeps needing topping up....perhaps water is the problem??

Any help/advice would be hugely appreciated please.

PS I know the boiler is not highly rated but we've only been in the house 3 months and I've got huge bills paying for my recent wedding so can't afford a new boiler....not yet anyway

Just tried another set of fuses just to watch and see what actually happens leading to the fuses blowing.....a couple of minutes after switching the power on and the boiler kicking into life I noticed smoke/steam from the '3 port valve motor' so obviously I turned the power off straight away........still no ideas if I'm looking at a repair or new combi boiler (gulp) ??!

Ahh!
Just when you mentioned the diverter it jogged the memory.
There is a common fault with these leaking at a seal and blowing the electrics. Needs new seal and the diverter rotated a bit to prevent any water running down again.

ah 6the diverter bush,aristons have this problem too as graham says you need a new bush and motor

 

[JoseGaf]

many thanks Graham/Gasman...have just removed the 3 port diverter motor to reveal a hexagonal plastic fitting with an electrode type fitting at the centre...its all wet and still leking slowly....is this an easy enough and quick job for an engineer to sort or could I do this myself?.....have seen Diverter Valve Repair kits for sale online. Thank you.

do you not think the diverter valve repair kit would do it, these are £20 ish whilst the diverter valve is £100+? The leak is definitely coming from the hexagonal plastic fixing which fits into the valve. Cheers

yes the repair kit should do it,tbh i dont work on a lot of heatlines but parts for them are a rip off

 

[JoseGaf]

great...just found a retailer near my work so can get tomorrow after work....will I need to drain the boiler or can I isolate the water in the system....? Cheers

 

[PlumbSafe]

you can just turn the in coming main and boiler flow and return isolation valves off, like 2 x 22mm and 1 x 15mm ball-a-fix valves under the Boiler. then let the pressure out the temperature and pressure relief valve which is inside the boiler, open a hot tap and also open the auto air vent if shut (also inside the boiler), this should drain most of the water inside the boiler, and then you can start your repair.

 

[JoseGaf]

cheers plumbsafe, I'll give it a go after work tomorrow

 

[PlumbSafe]

You can do it I am sure, you sound like you have some technical knowledge, hope you manage to sort it as I know weddings clear out the savings and leave you skint, let us know how you got on, Good Luck !

cheers, I'll be doing my homework before attempting it!
