Baxi combo boiler leak from DHW when not used for 5-6 hours

Hi

I have a BAXI NETA-TEC COMBI 33 GA boiler and every morning I come down to a small puddle of water underneath the boiler. The gas engineer has replaced two washers in the DHW and a new baxi brass adapter and tightens all connections, still the leak remains.

It does not leak when the hot water is being run it’s only leaks when the boiler is left for a long periods of time without use? any help would be greatly appreciated

Many thanks
 
Plastic hydro block best replace as it’s probably got a hair line crack
