Bosch Dishwasher Maintenance Tips
- 1Clean the drain filter and food trap after every few cycles
- 2Run an empty hot cycle with dishwasher cleaner monthly
- 3Clean spray arm nozzles with a toothpick to remove mineral deposits
- 4Check and clean the door gasket to prevent leaks
- 5Use the right amount of detergent — too much causes residue buildup
- 6Ensure dishes don't block the spray arms from spinning freely
- 7Run hot water at the kitchen sink before starting the dishwasher
