Checking and Replacing the I/O Valve Assembly
A. Disconnect the external drain line from the drain saddle and the white membrane drain line from the back
of the I/O Valve.
B. Place both lines into a bucket and verify the flow of water.
C. Open the treated water spigot and allow the appliance to flush for 5 seconds. Close the spigot and allow
the tank to refill (approximately 2–3 minutes).
D. While the tank is refilling, water should flow through both the white membrane drain line and the external
drain line into the bucket.
E. When the tank is filled, the I/O Valve should shut off the water to both drain lines. If the water continues to
flow through both drain lines, continue with steps F–M to replace the I/O Valve assembly.
F. Remove the decorative cover from the appliance.
G. Remove the locking clips and tubes from all ports on the valve assembly.
H. Unscrew both mounting screws.
Caution: Do not press down hard on the screws. Doing so may push the screws out of the plastic.
I. Remove the valve assembly, retaining the O-Rings.
J. Install the O-Rings on the new valve assembly
K. Position the new valve assembly and screw in the mounting screws until snug. Do not overtighten!
L. Reconnect all tubes to their appropriate locations and reinstall the locking clips.
