No lights on "Worcester 350" boiler
 

Was working fine earlier today but boiler now has no lights and no
indications on LCD panel.

Have switched on and off.

I've checked and 240V is getting to the circuit board.

Any tips or is it time to call in a repair man?

Any recommendations for a repair man in/near London SE3?

Many thanks

What LCD panel ?

do you mean the programmer ?

Are you getting low voltage back from the transformer (9v-0-9v ?)

Have you looked at the fuse on the Zagas 125 pcb?

Sorry yes, I mean the programmer.

Are the transformer low voltage point and Zagas 125 pcb fuse easy to
find? Can you provide directions?

BTW, the overheating switch has not tripped (it pops up doesn't it?).

And now the low pressure light (only) has come on. Still nothing on the
programmer display. I don't think the sytem really is at low pressure
because the indicator says 1.5 bar. However it probably was low until I
topped it up.

Thanks again

Sorry, I've now checked the fuses on the Zagas 125 pcb and the
sequencer PCB and both seem OK (about an ohm).

I've found something that looks like a transformer but it's labelled
with output of 24V at 16A (no mention of 9V). And I can't seem to get
much of a reading out of this but I'm not sure I'm testing the right
connections.

Thanks again in advance for any help

The transformer goes to a connector on that pcb

Don't you have a manual ?

It has a fault finding chart

It could be 24v, I can't remember offhand, but 16A ? I think not

So you need to work out whether you're a) getting mains into the
transformer and b) getting whatever the low voltage is, out
