sounds as if its leaking from the main diverter body,its a new diverter valve im afraid straightforward to change tho if u have good access on the left hand side

Its sounds like its leaking via the 'o'ring and showing at the grub screw.

No it wont but, if you change the DHW termistor it will.

Would you agree combispecialist

Also whilst your doing that. Whip out the plate to plate and clean out.

Plenty of info on here of how to clean heat exchangers.

kantago-where is this grubscrew located that u mean??

clf- leaking from wot "o"ring??

the grub screw i mean is located below dhw flow valve that keeps the flow valve attached to main diverter valve.....

 

[combispecialist]

[KANTGO]

it in the middle of the diveter valve there is 4 of them

with regards to luke warm hw......turn hot tap on and does the heating flow pipe get hot??if so it will need a new diverter

 

[combispecialist]
