I broke this round green thing while trying to ignite fire. Can it be fixed?
What does this show exactly. How do you fix this
How do I lower the pressure in this same boiler?
Thanks a million
5 minutes waaste of time. It could simply be that the boiler output is too high for the system load.
What a waste of time.
Once again, another pointless video offering nothing as to cause or solution. Another Charlie Chaplain silent movie.
It totally helped me!

Didn't know they had ariston boilers in Pakistan
OMG 😧 who fitted that? The pipe work is terrible.

Try: Turing off main switch of boiler and then close water inlet to boiler Wait 2 min Now turn on water supply and then turn on main switch. Push red button (Lock out reset button) Good luck 👍
You're only 11 years too late 😂
Sooo go on then???
MT10 Timer on worcester/greenstar 28i are just a rubbish clock. Always breaking down. Worcester should replace every single one as there are known faults with them.
pointless video, WTF???
1:43 about how to push a button, really useful. As previous comment states. No RF connection to the thermostat shown by flashing antena icon.
