to check the thermostats you then need to know each one.
the first only has two wires and is only for the boil cycle, ignore this one unless the machine is failing on that cycle only
the other thermostat is the normal wash one.
your meter will be able to test the 40 degree by placing the leads on the contacts (left and one of the right ones first) and then placing the stat in a cup of boiling water (ensuring your test leads do not touch the water surface) if it gets a continuity circuit after sensing the heat then it is okay...if not then try again with the other right hand contact---if still no joy then replace stat and see how you go
