Ikea kitchen mixer tap

has anyone had this problem
the mixer tap is dual flow
no matter which water is flowing through nthe central core it splutters annoyingly
i have tried all sorts to solve this
drained the system etc
hose pipe for air lock
would a single flow mixer be the answer as it just occurs when the water is fed through the central core
thanks for any help

What type of hot water system do you have? Mains pressure or gravity fed.
Some taps require a working pressure of a least 1 bar, or they will not operate. Generally the taps with the big sprinkler heads. Robiow
