Bosch might be a leading oven manufacturer but is not free from errors. Errors are a common occurrence in appliances and can be fixed without scratching your head. Simply note down the error code showing on your Bosch oven screen and check out the error type. To help make the process simpler we have listed down some of the most common error codes for Bosch Ovens.

After two consecutive temperature readings are made successfully, heating will resume and error will be cleared. See Communication Schematic.|
|E104-E204||Cavity 1 / Cavity 2 temperature sensor shorted. Temperature sensor shorted to ground. Cooling fan will operate at high speed and heating will stop. After two consecutive temperature readings are made successfully, heating will resume and error will be cleared.|
|E106-E206||Cavity 1 / Cavity 2 door latch does not lock. Latch operation not determined by control module. Door latch does not lock after 1 minute and further attempts will stop. Error will be cancelled and normal operation resumed if a locked door is no longer required. See Cavity 1 (upper) Small Load Schematic.|

Door latch does not unlock after 1 minute and further attempts will stop. If the latch is detected in open state for more than 10 seconds, the error will clear and normal operation will resume. See Cavity 1 (upper) Small Load Schematic.|
|E115-E215||Cavity 1 / Cavity 2 temperature in unlocked cavity too high. Temperature in unlocked cavity exceeds the allowable temperature. Oven will stop heating and door will lock. When temperature reaches allowable range, door latch unlocks, error is cleared, and oven will resume heating.|

|E126-E226||Cavity 1 / Cavity 2 door latch error. Switch signals lost by latch position switch. If a locked or unlocked signal error occurs, all heating elements will be disabled. Error may be cleared only by a software reset. See Cavity 1 (upper) Small Load Schematic.|
|E303||Electronics Delta temperature too high. Temperature sensor on the control module detects temperature changes that, over time, are higher than limit value. Control turns off heating elements and fan defaults to high speed. When cavity temperature reaches 212°F/100°C, heating will resume and error will be cleared.

Error messages on the display
If an error message with “E” appears on the display, e.g. E05-32, touch the ‘timer’ button. This will reset the error message. Reset the time, if necessary. If the fault was a one-off, you can continue to use your appliance as normal. If the error message appears again, call our after-sales service and quote the exact error message and the E no. of your appliance.
Maximum operating time
If you do not change the settings on your appliance for several hours, the appliance will stop heating automatically. This prevents unintentional continuous operation. When the maximum operating time is reached depends on the various different settings that have been configured on the appliance.
Maximum operating time reached: F8 appears on the display. Turn the function selector to the “Off” position. You can configure new settings if required.
Bosch Built-in Oven Basic Setting
There are various settings available to you in order to help use your appliance effectively and simply. You can change these settings as required. Depending on the features of your appliance, not all basic settings will be available.
If a fault occurs, there is often a simple explanation. Before calling the after-sales service, please refer to the fault table and attempt to correct the fault yourself. You can often easily rectify technical faults with the appliance yourself.

Types Of Heating And Functions
How do I clear the error code on my Bosch oven?
Switch the appliance off and on again. - If the fault/error was a one-off occurrence, the message will disappear.
What is error code E011 on Bosch oven?
Long pressing of one of the buttons the malfunction may occur due to water or dirt entering the control panel; For this, the control panel needs to be cleaned of the dirt and the moisture.
Why is my Bosch oven not heating up?
If your oven is turning on but won't heat up, the issue could be with your heating element. Inspect your heating element for burns and damages. A functioning element goes bright red, so if your oven heating element is damaged, it will remain dark grey.
