Bosch Dishwasher Dispenser Optical sensor, center door mount, TP3 12008380
Center-door-mounted dishwasher detergent and rinse-aid dispenser assembly with an optical sensor (TP3). It holds detergent and rinse agent and releases them during the wash cycle.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Dishwasher powers on and runs full cycles normally
- ✔ Water fills and drains correctly — only detergent dispensing is the issue
- ✔ Detergent type and amount are confirmed correct — not a detergent issue
- ✔ ONLY problem is detergent door not opening, detergent not releasing, or dispenser latch broken

🔧 Common Symptoms
- Dishes come out dirty or with soap residue after a full cycle
- Detergent pod or powder still in the dispenser cup after cycle completes
- Dispenser door visibly stuck closed or won’t latch properly
- Clicking sound during cycle but detergent door doesn’t open
- Dispenser door spring broken or latch cracked
- Rinse aid compartment leaking or not sealing correctly
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing the soap dispenser restores proper detergent release and clean wash results immediately.
