Morning All,
I have a 2yr old Worcester Bosch Greenstar CD30I which has just started playing up and the Worcester engineers is strugling to explain it.
I call it in after the unit purged on U9 code on teh display and then went cold. Its also showing the syphon fill code frequently. I had hte eng here and he plugged his laptop in and told me 'the boiler is fine. it must be air in the system or inballanced flow'. OK fine, so go around and open all the valves. One of whch was closed on the upstairs bypass. So i open it and the heating is running normally, all rads hot. This morning I got up at 5:30 to bleed the system when fully cold and its heating ok now.
Then I turn on a hot tap and the temp runs up to U9 in about 3 sec and prurges the system. So now we are freezing again and waiting on Worcester to send another guy!
Any help and advise much needed and appreciated
