Ariston Eurocombi A/23MFFI

[Robbsi]

Hi, i have an Ariston eurocombi A23MFFI boiler, the boiler will not supply hot water unless the heating is on for about 5- 10 minutes. The hot water tap has to be run very slowly for the water to be at a temperature for bathing. I had an engineer look at it about 6 months ago due to it failing to ignite. The engineer diagnosed and fixed the problem, it was fine for a while until now.

I have looked online and figured out for myself that this type of boiler is not the best but i have inherited it and finances dictate that i'll have it for another while so that's why i need to repair the fault.

Can anyone help me out ?

Thanks, Robbsi.

Do a search on diaphragm or diverter

It's about 70mm diameter in your case and does not have a hole in the middle. Probably about £11 plus vat.
