Ferroli Optimax 31c no hot water

[Macktt]

Hi Guy's this is my first post (I wasn't even aware such an amazing resource existed) so well done!

I have A Ferroli Optimax 31c that sprung a leak on the water inlet plastic manifold (39837170) due to a hairline crack.

Now, I am aware that these boilers do not have a good reputation but I have had this in for about 4 years and this is the first issue I have had with it.

The boiler was fitted and serviced by a friend of mine (Gas Safe registered) who unfortunately moved on to pastures new (Australia) a few weeks ago, so I had to use an engineer that was recommended by a friend who came and replaced the part today. After replacing the part the boiler came on fine, the heating kicked in but when I ran the hot water it got warm for a few seconds then went freezing cold? and now I have no hot water at all.

The engineer has said that it must be the diverter valve or flow meter? but I have never had any problem with hot water until this part was changed?

Does anyone have a clue what this could be? any help we be massively appreciated.

Yep it's a common fault after they have been drained down . Your friend will find it easy and fix it. FYI you won't get any advise on here regarding repairing a gas appliance as it's illegal and dangerous for u to do. For those who know it heats DHW same as an intergash!
