My doors don’t open or run smoothly! what should I do?

This is usually down to fit rather than a fault. Using the spanner supplied, follow your manual to check the doors run level and aren’t too tight in the runners.Once they’re moving freely, a silicone lubricant spray on the door wheels (cams) helps keep them that way! regular cleaning and lubrication stops water and detergent build-up from making them stiff.
