Worcher Bosch 24i System Boiler

[JohnH]

Hi All
Need some advice please.

I recently replaced the HW/CH system in my late Mother’shouse in PolyPlumb plastic complete with new radiators and solar cylinder. Unfortunatelywhen the Worchester Bosch 24i boiler is switched on it only runs for 10-20seconds then shuts down with the blue power light on continuously.
The Gas Safe heating engineer who is helping me can’t fathomout what the problem is. He has checked the gas pressure at 24mBar and thewater pressure at 1.5Bar and also bled the air out. He then rang W/Bosch and they suggest it could be ablockage in the system somewhere. I have checked all the pipework including the condensepipe and have even removed the 3 way diverter valve, still the same. The boilercommand signal is present. I do need to point out that the boiler did layunused in a box for nearly 3 years before being reconnected to the new system butit worked perfectly OK up until then. Does anyone have any other suggestionsotherwise I will probably need to call in Worchester Bosch.

Thanks
JohnH

You'd imagine so buddy? you never know though?
If the pumps running, the valves are open but your not getting the heat going anywhere then something is closed or blocked.
If you are getting circulation but your boiler isn;t running past 15 seconds then it maybe a boiler issue

Flow and return fitted back to front ,, !

 

[lame plumber]

boiler sat in its box 3 years. there is a clue there for some folks

Maybe if your GSR engineer had actually installed it instead of just being paid to sign it off he might have a better idea of the issue with the system.

Thanks IDCHAPPY we will check the circulation also there is no air/water coming out of the pump bleed screw.

ps. Open the boiler flow/return isolators.

Has the air vent on top of boiler heat exchanger been vented?? Sounds like circulation caused by air lock....
