Dishwasher racks are difficult to slide or feel rough when pulled in and out.

Safety first: No electrical work is required; ensure the machine is off before working inside.

• Inspect wheels and rails: Remove the racks and check the wheels for flat spots or cracks. Inspect the rails for bends or obstructions.
• Clean rails: Wipe the rail channels with a damp cloth to remove grit and dried detergent.
• Replace worn wheels: Fit new SMEG rack wheels or complete rack assemblies if the originals are badly worn.
• Check alignment: Ensure racks are correctly seated on the rails and not twisted.
