E31 at a glance
Fault: contact sensor frequency too high
Cause one: the electronic control board is defective
Cause two: something foreign is getting in the way of the contact sensor
Recalling the last error
Codes show up as an E plus two digits. Keep cancel and start pause pressed at once for 6 seconds and the display gives the last error on record; E00 is shown when none was recorded.

The sensor and the wires leading to it are looked at first. If they are fine, attention moves to the electronic control board.
