Bosch washer E27 error code

The E27 fault code means that the door is being locked.

Here is what I did about it:

1. Press “Allergy rinse” and “Spin Selection” simultaneously.
2. Choose “Cold” using the mode selection knob. There were several codes blinking on the LLCD display: the machine is resetting.
3. Wait a few seconds and turn the knob to “Off”.
4. Switch on the appliance and try to run a cycle.

Most likely, the error will be gone and your machine will be working like clock again!
