and retry washer cycle.

Yes

(1) "AC"

Lower than 20 volts "DC"

20 volts "DC"

"E:SP" still continues

Are all the control

wiring harnesses

connected between

the two controls?

"E:SP" is displayed on

EDC control.

What is the

measured voltage

at "H1-7" to "FS-2"

on the motor control

board?

Change either motor or
