Hi,

Check all the power supply fuses.

Hi,
If you checked the 3 switches out of the machine that could be the problem. Sometimes the metal actuators for the switches will not depress them far enough causing the false message. You could also be running into dirty contacts. I would first check the actuator and then if that did not resolve it then replace the switches.
