Worcester 28i junior

[Deelta]

The low pressure switch could be blocked (top rright its got 2 wires to it and its circular in shape,try taking it out and see if its dirty,if you can gently push something into it and hear it click.have you linked it out

Thanks I'll try that, any idea what is the link to the service instruction?

check the low pressure switch top right of boiler ( if you are electrically competent if you dont know how to do it then you are not elec competent) the junior 28i is weird in that it will spark when the lp switch is open circuit.....I asked worcester why once and they could not answer me...i assume you have checked pressure in boiler

did you mean the overheat stat? thanks any way if you meant that it was that, it was open circuit and the boiler worked when I bypassed and I ordered new stat, thanks a lot.

thanks I meant to say it was the LP switch and not the overheat stat, spot on many thanks
