The E27 fault code means that the door is being locked.
Here is what I did about it:
- Press “Allergy rinse” and “Spin Selection” simultaneously.
- Choose “Cold” using the mode selection knob. There were several codes blinking on the LLCD display: the machine is resetting.
- Wait a few seconds and turn the knob to “Off”.
- 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!
