Grant Vortex Boiler tripping 3A fuse

Lex Luthor

Came home this evening to find my Grant Vortex switched off when it should have come on through the timer

Checked the boiler and no power to it and found the 3A fuse in the wall to be blown

Replaced the fuse, started the burner for a split second and popped again

Its about 2.5yrs old

Do these come with a 5yr warranty? I seem to recall something like this when we bought it as long as you got a registered service agent for Grant and kept all your paperwork which we have

I thought I heard something on the radio last week that a lot of people were having issues with their condenser boilers due to the pipe outside being blocked but snow is all gone now and it was fine last week

Thanks

I would check the circulating pump. Unplug it or take wires out and check again. They have been known to blow fuses

It may be an issue with the circulation pump.
Best to get your service technician out to investigate it.

also, for an oil boiler it should be a 5amp fuse

Thanks all, removed the wire feeding the circulating pump and boiler fired up

Will get someone out to repair/replace pump. Think pump is original since 1996 so no harm swapping out
Thought it had been done when boiler got replaced a few yrs ago

Any idea roughly what the cost of the pump+labor will set me back?

Where you based. ?? A dab pump plus new valves would be under 100. Might cost the same again if he has to drain down and change valves.

Grundfos ups2 is a good pump but abit more expensive
