Baxi 80 Combi Boiler H/W Heating cooling

[badger81]

Hi All,
I have a Baxi 80 Combi Boiler, All is working fine with the central heating. But when I use the hot water it seems to cycle hot water and warm water. I have watched the temp leds and it gets to 80 then goes down to 60 then back up to 80 and repeats this cycle.
I thought it was the water temp being turned too high so have turned this right down at the boiler, it did seem to improve for a short time although still hasnt completely fixed the problem.

Has anyone seen this before? Or got any ideas??

Best Regards.

Can't remember this model!

Sounds like plate heat exchanger is partially blocked.

Sorry, I just viewed my original post, it is a Baxi 80 model,
As described, it heats to 80oC then after a minute or so cools down to 60oC and then reheats back up to 80oC,

Any ideas??? [/b]
