My dishwasher makes a high-pitched whirring sound when the cycle is finished, and you open and then close the unit. I have figured out that it is the vent driver assembly motor.
The technical manual says that you can turn the vent driver assembly off by hitting any key on the control panel. Hitting any key in fact stops the whirring sound, so i am very sure the part making the chirping whirring high pitched sound is the vent driver assembly.

My question is whether or not i can lubricate this part, and if so, what should I use to lubricate, or do i need to replace it altogether to stop the annoying sound without hitting a key on the control pad to turn the motor off?

Thank you in advance for any thoughts you may have on this subject.
