DIY Solutions

Rearrange Load for Proper Spacing

Easy 5-10 minutes

1. Unload and remove all racks gently.
2. Place dishes so that spray arms can spin freely and water jets reach all surfaces.
3. Ensure taller items do not block the detergent dispenser or door closure; avoid nesting of utensils.

⚠️ Safety First: Ensure dishwasher is off before rearranging to avoid accidental start.

Check Spray Arm Movement

Moderate 10-15 minutes

Tools Needed: Soft cloth

1. Before starting a cycle, use your hand to spin both upper and lower spray arms.
2. If blocked by dish placement, rearrange items to clear space.
3. Wipe any debris off spray arms that inhibit movement.
