Without one my guess is it's the device that checks if the water has
reached the correct fill level.

Thanks, it is exactly like this one: http://www.homespare.com/Pictures/thumb/50141.jpg

The red part is actually a float.
When the machine fills with water the float rises and activates a
microswitch to turn the water off.

Can't recall what the yellow bit does.

It operates the other microswitch: dishwashers need to sense
both "enough water to wash" and "drained properly".
