Hello,
I have a Vaillant ECOMAX 824/2E,
When the cold water is being ran on full, the boiler turns on (sounds like the fan) and status is 17 (HW icon appears for a split second but boiler never fires up).
What could this be? It is rather annoying haha
When hot water is ran, boiler comes on as usual and fires up.
I dont know if it makes any difference but CH is depressurised.
Thanks,
