No hot water novice requires your help

[idc1873]

Your help please, (novice) Not getting any hot water from my Myson Orion boiler the heating works fine but no hot water. On pressing boost option for water only it fires up fine but after a short while cuts out, it sounds like its boiling over inside as though it isnt gettin enough water making the stat cut out. The Grasslin QE2 timer still shows water ON, if i leave it for a while then try the boost agian it does the same thing.
Any ideas
