Check the drain valve for obstruction.
Carefully remove any obstruction found.
If no obstruction, check to make sure both
connections to the drain valve are plugged in
securely. If connections are secure, operate
the drain valve using the drain valve test in
tech mode. If no drain valve movement,
test to make sure the drain valve is getting
24VDC from control board when testing both
directions (open and closed) from connector
P9 pins 3&4. If voltage is present and no
movement, replace drain valve motor. If no
DC voltage, replace control board
