Identify relay for door lock

[white66]

Hi folks,

I have an Electrolux EWF10843 in front of me with an intermittent, non-opening door lock.

Have checked the following;

Pressure switch and tube

Door lock

Inlet solenoids

All pass with flying colours so suspecting the relay on the main board.

However, I cannot find a service manual for this model ( have seen 1 UK video for changing the lock so I have assumed this model is available in the UK) so cannot identify which relay I need to attack.

Anyone know which or a test to find it. I've elected not to remove the board until I have the info.
