DIVERT VALVE REPAIR OR REPLACEMENT:
Disconnect electrical power to the BE unit before repairing or
replacing the Divert Solenoid Valve.
Repairing the Divert Valve:
1. Find the Divert Valve in the piping of the unit. It is brass in color and has a large hex nut on one side. If
you are agile enough, you may be able to reach the Divert Valve through the access hole in the top panel
of the BE unit or from underneath the front opening. Otherwise, remove the top panel from the unit. Be
careful—there are four wires and a hose attached. Set the top on its right side on top of a crate or other
support near the right front corner of the unit.
2. Locate and remove the coil portion of the valve. It is a black box attached to the valve and is held on with
a yellow or silver clip. Remove the clip and slide the coil off of the “stem” of the Divert Valve and set
aside. Do not unwire the coil—replacement of the coil is rarely necessary. However, its a good idea to
verify that the wire connections are secure. To check the wire connections, remove the small screw that
holds on the coil’s cover, exposing the wire nuts.
3. At the base of the Divert Valve’s stem, there will be a large hex nut. Loosen this nut, and carefully
remove the stem. Be careful—there will be a plunger assembly (with spring), and a plastic spring seat
inside the stem.
4. Most likely the plastic spring seat has melted. Remove the plastic spring seat—the Divert Valve can
work without it. Also, clean the rest of the inside of the Divert Valve. There will be two small metal rods
in the valve’s body. Clean them and make sure they move freely. Once re-inserted, the rods should
spring back when pushed into the body. Also clean and dry the inside of the stem.
5. Reassemble the valve. Tighten the hex base of the stem onto the valve body to 175 lb-in. Place the coil
and clip back into position. Set the lid back on the cabinet (if removed) and check that the wires and hose
attached to the lid are not loose or kinked.
6. Test the operation of the repaired Divert Valve by placing a jumper wire between the terminals of TAS3.
Restore power to the BE unit. Verify that there is at least 3 1/2 gallons of liquid in the Process Tank and
that the Pump Reservoir is properly filled.
7. Turn the BE unit ON and watch for vacuum on the Vacuum Gage. The vacuum level should begin to rise
until it reaches at least -24” Hg.
 If OK, disconnect power, unjump TAS3, put everything back together and try a real recycle run.
 If low or no vacuum, hold your finger over the Processed Water Hose. Does the vacuum go up? If
so, replace the Divert Valve body, part number J101885.
