What's Happening

The detergent dispenser solenoid circuit has a problem. The dispenser may not open at the right time during the wash cycle, leaving detergent trapped and dishes poorly cleaned.

How to Fix It

Check that the dispenser door isn't blocked by dishes or hardened detergent residue. Clean the dispenser thoroughly. If it's physically clear but still won't open, the solenoid or its wiring may need replacement.

Frequently Asked Questions
What does E19 mean on a Bosch dishwasher?
E19 indicates a detergent dispenser problem. The solenoid that opens the dispenser during the cycle isn't working properly.
Why is my Bosch dishwasher not releasing detergent?
Hardened detergent residue can block the dispenser door. Clean it thoroughly. If it's clean but still won't open, the solenoid mechanism has failed.
Can I use detergent pods to work around E19?
Placing a pod in the bottom of the tub bypasses the dispenser. This works as a temporary solution, but the pod dissolves immediately rather than at the optimal cycle point.
