Help Needed

Hi guys

I have an issue with my boiler and wondered if you could have a look at the info provided and let me know what you think I should do.

I have a Worcester Highflow 400 RSF and up until yesterday it was perfectly fine. Now though I have no Hot Water and no Heating. The boiler seems to be on and when I turn a tap on or turn the Central Heating on the "in demand" light glows green, which is normal. However I noticed yesterday that the pressure dropped to 0, so as you do I topped it up to 1.5 bar and followed the instructions to re-ignite it. After abit of time the boiler kicked in and it provided both hot Water and Heating. Today I have the exact same issue no hot water and no heating and the pressure was at 0. I followed what I did yesterday but I cannot get this damn thing to provide for me. Annoyingly there is not an ignition window so I cant even tell if the damn thing is ignited or not.

Oh and one last thing when I put the heating on the "in demand" light does come on green but there is no woosh noise(not really sure the technical term for this but woosh seems close enough

Any Ideas?
If you need any further info just let me know and I will try my hardest to provide it.

you have a leak or knackered expansion vessel causing the pressure loss,it probably wont light as the high limit stat has kicked in /failed as its"in line"with the thermocouple and the combustion door needs to come off to check it you need a gsr engineer,he/she will check the expansion vessel at the same time try looking to see if you can find any leaks in the system
