Vaillant turbomax 837

[Dangee]

Hi guys (&girls) 1st post!!!
Weird problem when boiler running in hot water & heating, fan (& burner presumably) rapidly modulating high & low (but not going out).
All getting to heat ok but unusual modulation. Had quick look today but returning tomorrow.
Any pointers???

Hello Dangee,

Thanks Novice. I'm a newbie.
Problem solved though. Weak pump, all done now.
