Multipoint locks won't retract fully

[cammy2207]

Multipoint locks won't retract fully, meaning door won't open, unless excessive force is applied to handle at lowest point. I can open it but my wife and children are now really struggling.

After lifting the handle to activate multi point locks, they only go back in by 90% when handle pushed down, leaving enough of the locks sticking out to stop door opening.

Any idea how to fix? Many thanks

This is it sticking out

This is how it should be

Tried wd40?

Well!.... I haven't but it seems not to be sticking, more like the handle must be pressed down very hard to get the locks to retract that last little bit. However for the sake of ticking boxes, I will give them all a spray.

To add, to get the multi point locks to retract to the '90%' point takes very little effort (as you would expect), it's that last bit that takes so much downward force on the handle

Sounds like the mechanism has failed or is failing.

Spot on, it's worn and you'll find there's a lot of slop in the hooks
