gasket in the sump. Make sure the gasket is in place
when reinstalling the pump or the unit will leak
water into the base pan.

Wash Diverter Disassembly

The wash diverter is designed to direct the water
flow to the upper arm, lower arm or both. When
required, the main control sends 120-volts AC from
terminal P6-2 (gray) wire on the control board and
neutral to activate the motor. The yellow wire on
the diverter sends line voltage back to the control
board to P6-5 (line in-yellow wire) and tells the
controller the position of the diverter.
