How do I fix E305 error message on my Bosch Oven display? 

Here’s the simple solution: Reset the breaker and the problem will be solved. Ensure not to get the front control panel wet when cleaning the oven.

In the instance where the oven will not power on, first, try cutting power to the unit for 10 minutes and turn it on again.

If that doesn’t work, unplug the unit for 24 hours. This will give the oven enough time to dry out – if water got into it – and hopefully reset.

Furthermore, if the issue still persists, take the oven apart, and be sure to check all the wires. There might be a loose connection or a broken wire.

If you have the same problem after resetting and re-applying power, you will need to get and replace the main control board on the back. It would cost around $200-$250.
