Baxi Platinum dodgy hot water

[Aquariusplumb]

Hi all can someone help me. Baxi platinum boiler works great in ch mode, turn tap on green neon comes on, red Hall effect sensor comes on, boiler fires but water foes hot then cold. Sometimes hot water runs warm but never really hot. Felt hot pipe under boiler with bath tap blasting and pipe doesn't really heat up! Plate heat exchanger partially blocked? Thanks

Going down the heating?

Il have to check tomorrow. It's only been fitted 3 weeks just wondered if it was something simple before I call the heat team out to it.

3 weeks? As long as you know the system was flushed and cleaned best you could then I'd be kicking it to them ... could be a dodgy Phex?

Yeah I had It running for an age with chemicals in and out constantly cleaning the magnaclean til there was nothing sticking to it and checked it today when I popped in and was clean. Never had a problem like it with these boilers. I suspected the phex. Oh well heat team here you go.

Don't shoot me down okay... Fitted an Apollo for a landlord a few months back ... just wouldn't work on heating or water! Kept overheating! Ended up replacing it!! Over the years seen loads of issues on installation. Just send it back to manufacturer! Not good when the custard has to live with a dodgy boiler but what can you do?

Myson Apollo ( super sexy band k rated? ) for DHW check that the diverter head is working properly, I would assume so as ur getting CH but not domestic. Is Hall effect a constant light or weak flickers? Had odd instance where sensor was bunged up. Also u have got hot and cold in correct orientation? I have NEVER done this tho. Works for few days then intermittent. Also mixer tap or shower passing? Fit a check valve or two?

Hot and cold crossed. Check that first. What does the display do?

bet you a mars bar the lead field engineer says its a installation fault knowing full well something on the boiler has been massed produced wrong not that thats ever happened to baxi - NOooooo
