Vaillant 937 low water flow HELP!!

Hi all,

Av just returned from 2 wks holiday and switched my Vaillant Eco 937 boiler back on & relised that my hot water flow has suddenly gone low. Before I could have 2-3 taps on and hot water flow would be good but now that's not th case. Also their seems to be noise coming from pipes whn central heating is on, not from boiler but noise from pipes. Could it be air?

    What are the cold taps in your house like? The same as before or less flow?

    Did you turn the stop !!!! off when you went away and now, perhaps, have not turned it fully on, or maybe it has broke?
  • Cold tap is fine, good pressure also stop tap is turned full.
