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 8 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 -19”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.
