I have an IKEA LOVIKEN AA-291347-1 faucet. It leaks between the 2 handles at the connection.
I removed the screw behind, but I cannot remove the top center part.
Do you have any idea how I can open it to change the seal inside?
I believe that part is factory assembled, not removable. You may want to check with the manufacturer, if there's a local 800 number. Maybe they'll give you a brand new one.
