Ocean Alpha 240p - no hot water, should I get a plumber?

[AlkaXS]

Hello

After reading a post this forum, I understand that the most likely cause of the lack of hot water is the diaphragm:

Now, I'm no fool but I'm not a plumber, do I need one to do this job? And if I do call someone out, how much should it cost?

If I can do it myself, is there any particular sort of diaphragm I need to buy?

Cheers

Peter

They are pretty easy to change but the diaphragm kit for these is about 25.00 plus an hours labour.

If you do it yourself, take photos and make drawings at every step of dismantling - it's one of those jbs that you can find yourself asking WTF is that bit for or which way round does that go
