Kind of a generic question. When you take the bottom out of the Whirlpool Designed front loaders, there is a equipment grounded conductor on a microswitch connected to the motor control. What is the purpose of having a switch on that ground wire?

Please relocate this to the laundry room, my bad!

i think it is a safety device...closes the path to ground on normally ungrounded components...i.e. the motor, etc...

Saw the photo.  Where exactly is that switch located?  Agree with Brother Kurtius about it being a safety.  What is the switch actuator button against?

The motor isn't grounded during normal operation, because it causes interference with other electronics in the home, but when servicing the washer (toe kick removed) the micro switch grounds the motor for safety.

The actuator is against the lower panel, (this machine happened to be on the lower left hand side)   that you drop down to gain access to everything under the tub, drain pump, Motor Control, etc.

I believe you are wrong on this matter.  There is one of these ground switches on the back panel and front access panel.  If the panels are removed the switch is in an open state breaking the ground loop.

 

On the Duet Sports you will get a F28 error if you have the access panels off and try to run it.  You have to tape the switches closed when testing with panels off.

 

On the standard Duet's you don't get the F28 error with the panels off like you do with the Duet Sport models.

This is the Grounding Circuit for the Duet Sport Washer Motor and Heater, notice that during normal operation both of the switches are in the open position leaving the heater and motor not grounded.
