Valiant ecotec 28 not working

[Damo-bar]

I’ve got a Honeywell st9100c and it fizzled and cut out yesterday no lcd screen working so changed it today and still no power in the boiler any suggestions please

what’s happening? No power to the boiler or it’s just not turning in?

Did you have a external timer already installed as it’s sounds like you’ve connected something to mains that’s shouldn’t be eg 240v

Have you checked your 3 Amp fuse for the heating supply.

@ShaunCorbs Sounds like he's just swapped the clock for like for like to me

I’m not sure the timer has come on but nothing on the screen on the boiler

did you isolate before you swapped eg turned the fused spur off etc ?

you tried pressing the power button on the boiler ?

Have you altered any wiring or just clicked one clock off and fitted another

I turned off took out the fuse swapped the unit and replaced the fuse switched on. The timer came on but nothing on the boiler

Depending on the age of the boiler it might be under warranty or you could get a local pro in

Either the clocks blown something in the boiler when it's gone, or you've had a power surge that's taken the clock and the boiler out at the same time.

Time to get someone in i'm afraid.

Are you able to confirm any voltage presence at the fused connection? Eg to the fcu and load to boiler?

Ok, then as per the others, might be time to get someone in, could be a loose wire, or a blown fuse inside the boiler.
