Bosch Dishwasher Error Code E09 — Heating Element Error
What this means
The E09 error indicates the dishwasher's heating element (integrated in the circulation pump on most Bosch models) has failed. Dishes won't be cleaned or dried properly because the water can't reach the required temperature.
Alternate codes: E9
Step-by-step fix
2 stepsPower cycle the dishwasher
Turn off the circuit breaker for 5 minutes, then turn it back on and run a cycle. Occasionally this error is caused by a temporary glitch.
If the error only appeared once, the power cycle may resolve it.
Check if water is hot during wash
Open the dishwasher mid-cycle (carefully) and feel the water temperature. If it's lukewarm or cold, the heater is likely not working.
Run hot water at the kitchen faucet for 30 seconds before starting the dishwasher to give it a head start.
When to call a professional
On most Bosch dishwashers, the heating element is built into the circulation pump — replacing the heater means replacing the entire pump assembly. This is a professional repair.
