How to Repair a Clogged Spray Arm in a Bosch Dishwasher

In a Bosch dishwasher, the spray arms have openings that release water into the washer. The force of water pumped by a motor causes the arms to spin and spray water and detergent mixture onto your dishes. If the spray arms are clogged with food, grease and dirt, not only will the dishwashing time likely be longer, your may also see unsatisfactory cleaning results. Cleaning the spray arms is a troubleshooting and maintenance task that you should perform frequently.
