Dishwasher racks are difficult to slide, or upper rack keeps falling or tilting.

Safety first: No electrical work is required; ensure the dishwasher is off while working inside.

• 1. Remove racks: Pull the affected rack out and release the rail end stops to remove it completely.
• 2. Inspect rollers and rails: Check Hisense rack wheels for cracks or flat spots and rails for bends or rust.
• 3. Clean tracks: Wipe the rail channels with a damp cloth to remove food and mineral deposits.
• 4. Replace worn parts: Install new Hisense rack rollers or rail end caps as needed. Ensure they snap securely into place.
• 5. Reinstall and test: Slide the rack back in and confirm smooth movement and proper support.
