Could be a sticky three-way valve. Get the engineer back!

Sounds like the diverted valve sticking.I have a very old Valiant boilet that nwas doing the same about 12 years ago, I just moved it with a heavy screw driver the sprayed a little wd 40 no trouble since. But I don't know your boiler my diverter I think is hydraulic not electic but if I am wrong I stand corrected.
