Can anybody please help ?

I have a 6 year old Valliant TurboMAX Plus 828e Combi Boil and have starting to have problems with the Hot Water.

Central Heating works fine, but when I turn the hot water on the water comes out luke warm (boiler temperature display shows about 35). If I turn on the hot water tap, the green light flashes and the amber light comes on, but the water temperature temperature starts to drop. When I turn off the tap the amber light goes off and the comes back on again until the temperature display reads about 79. If I then turn the tap back on the Amber light comes back on and the water start off boiling hot and then starts to drop in temperature until it back at 35 and the water in luke warm. The amber light stays on , while the tap is open, but the water temperature does not go back up.

I have checked to see that the boiler burners are running when the amber light is on and they are.

The diverter Valve has been recently replaced so I don't think this is the problem.

The tape water pressure seams the same as always.

Can anybody please give me any advise.
