Worcester 28i - bleeding and lockout

[Mrdini]

So - tonight for some reason, I had the bright idea to bleed my radiators. During bleeding, my boiler pressure dropped below 1 bar (& the fault light started blinking once a second which indicates a lockout, I gather).

So I topped the boiler up back up to 1.5bar. All radiators (except two towel rails) are bled.

However, the boiler won't come out of lockout.

I do not think it is a frozen condensate pipe as the boiler was off all day today until I started bleeding the radiators, so there shouldn't be any frozen water in the condensate pipe, I'd have thought.

I am happy to call out a gas engineer tomorrow if needed, but wondered if it was something simple related to me bleeding the radiators.... Sludge?

Thanks!

Have you followed the procedure advised for lockout? Its in manual and online

 

[Mrdini]

Yes.

Turn off and power to boiler.
While off bleed other rads.
Pressure the boiler.
Open all the thermostatic rad valves. Turn up wall thermostat.
Turn boiler back on and see if it goes.
If that don't work you need heating engineer

Hmm, no joy. Will try once more tomorrow in case it's because it's so cold out & it's the condensate pipe after all... Fingers crossed. Thanks!

Embarrassing - it turns out there was nothing fundamentally wrong with the boiler - the reset button was sticky and not resetting the boiler out of lockout. At least, all good!

Well done for feeding back that info.
