Mend Glowworm Betacom 24c Central Heating Hot Water

Glow worm Betacom 24c no hot water but central heating fine?

Hi,
I had a new boiler fitted about 8 months ago, everything has been working fine until last week, now for some reason my water will not run hot, it just runs hot for a few seconds then goes warm! The central heating is working fine and the 30, 40, 50, 60,70,80 lights are all coming on however when i turn the shower on the lights one by one switch off, any help would be really appreciated as cold showers in the winter are not much fun!!
Thanks in advance

Have same issue on same boiler. Diverter valve stuck on CH. You may be able to hear the valve motor buzzing because it is stalled. Power off and on fixes it for me.
