Setup and Installation

This section outlines the general steps for replacing the detergent dispenser assembly. Specific details may vary slightly depending on your dishwasher model. Refer to your appliance's service manual or online video tutorials for detailed visual guidance.

1. Prepare the Dishwasher:
   • Disconnect the dishwasher from its power source.
   • Open the dishwasher door fully.
2. Remove the Outer Door Panel:
   • Locate and remove the screws securing the outer door panel. Many Bosch models use Torx T-20 screws.
   • Carefully support the outer panel as you remove the last screws to prevent it from dropping. Set the screws aside in a safe place.
   • Once the screws are removed, gently lift and detach the outer door panel.
3. Disconnect Wiring and Hoses:
   • Identify the wiring harness and any hoses connected to the existing dispenser.
   • Carefully detach the plastic guide holding the wiring harness at the top of the dispenser.
   • Disconnect the two electrical wires connected to the dispenser. Pay close attention to any clips, especially on the upper left connector, which may require a small pick or narrow pliers to release.

4. Remove the Old Dispenser:
   • The dispenser is typically held in place by several fittings that lock behind a thin metal collar around the opening in the door.
   • Gently and carefully pry up the metal collar to release each fitting on the dispenser. Using thin, rigid plastic strips (e.g., from an old credit card) can help keep the metal collar lifted as you work around the dispenser.
   • Once the fittings are clear of the metal collar, push the dispenser out from the inside of the door. Be prepared for potential rinse aid drips if the old dispenser was full.

5. Install the New Dispenser:
   • Align the new 12008380 dispenser with the opening in the dishwasher door.
   • Firmly push the new dispenser into place until all fittings lock securely behind the metal collar.
   • Reconnect the electrical wires and reattach the wiring harness guide. Ensure all connections are snug.
6. Reassemble the Door:
   • Carefully reattach the outer door panel, aligning it correctly.
   • Reinsert and tighten all screws to secure the outer panel.
7. Test the Dishwasher:
   • Reconnect the dishwasher to its power source.
   • Run a test cycle to ensure the dispenser opens correctly and there are no leaks.

Operating Instructions

The Bosch 12008380 Detergent Dispenser Assembly operates automatically once installed. To ensure proper function:

• Detergent Loading: Open the detergent compartment and add the recommended amount of dishwasher detergent (powder, gel, or tablet) according to your dishwasher's instructions and the soil level of your dishes. Close the compartment lid securely.
• Rinse Agent Filling: Open the rinse agent compartment cap and fill with liquid rinse agent until the indicator shows full. Close the cap tightly. The rinse agent helps prevent water spots and improves drying.
• Automatic Dispensing: During the wash cycle, the dispenser's internal mechanism will automatically open at the appropriate time to release the detergent and rinse agent into the dishwasher tub.

Maintenance

To maintain the longevity and performance of your detergent dispenser assembly:

• Regular Cleaning: Periodically inspect the dispenser for any detergent residue buildup or blockages. Clean with a soft cloth and warm water. Avoid abrasive cleaners that could damage the plastic.
• Rinse Agent Level: Monitor the rinse agent level and refill as needed to ensure consistent drying and spot-free dishes.
• Seal Integrity: Check the seals around the dispenser compartments for any signs of wear or damage that could lead to leaks.

Troubleshooting

• Rinse Agent Leaking: If rinse agent is leaking prematurely, ensure the dispenser is correctly installed and seated flush with the door. Verify that the rinse agent compartment cap is securely closed. This replacement part is often used to resolve existing rinse agent leaks.
• Detergent Not Dispensing: If the detergent compartment is not opening, check that no large items are obstructing the dispenser door inside the dishwasher. Verify that the electrical connections to the dispenser are secure. If the issue persists, the internal solenoid may be faulty, which this replacement part is designed to address.
• Incorrect Part: If the new dispenser does not fit or function as expected, double-check that the part number 12008380 is indeed the correct replacement for your specific Bosch dishwasher model.
