Glow Worm 30s1 boiler issue only hot water when heating is on

Hiya...I am new to this site and hoping someone will be able to give me the benefit of their experience re a Glow Worm 30s1 central heating boiler.
Me and my wife moved into our house a week ago and have a problem with the hot water in that you only get hot water when the central heating is on. We have spoken to the previous owner and she said she had the same issue. We have had a gas engineer out to look at the boiler (which is about 20 years old at a guess) and he says the problem is the 3 way valve but we cannot locate it anywhere in the house. Before we start ripping up floorboards etc does anyone have any experience of these boilers and have any suggestions as to what to try first?
Many thanks in advance for any help and suggestions.
Jon
