MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the filter
valve through the regeneration cycles to check op-
eration.
Remove the top cover to observe cam and switch
operation during valve rotation.
DISPLAY MUST SHOW TIME AND DAY
1. Press and hold the RECHARGE button for 3
seconds until RECHARGE NOW flashes in the
display and the filter moves into the fill cycle.
O.UU
RECHARGENOW
...If the motor does not run, check the motor and
all wiring connections.
Check for fill water flow to the brine tank. If water
does not enter the tank, look for an obstructed
nozzle and venturi, fill flow plug or brine tubing.
2. After verifying fill, press the RECHARGE but-
ton to move the valve into brining. A slow flow of
water to the drain will begin. Verify brine draw
from the brine tank by shining the flashlight into
the brinewell and observing a noticeable drop in
the liquid level.
If the unit does not draw brine, check for...
...dirty or defective nozzle and venturi
...nozzle and venturi not seated on the gasket, or
gasket defective
...restriction in valve drain, causing a back- pres-
sure (bends, kinks, elevated too high, etc.),
...obstruction in brine valve or brine tubing
...inner valve failure (obstructed rotor disc, wave
washer defective, etc.)
NOTE: Be sure a salt bridge is not preventing con-
tact of the water with salt.
3. Again press the RECHARGE button to move
the valve into backwash. Look for a fast flow of
water from the drain hose (see specifications, page
4-1).
...An obstructed flow indicates a plugged top dis-
tributor, backwash flow plug, or drain hose.
Be sure household water pressure (well system) is
maintained at a minimum of 20 psi. Adjust the
pump switch upward, if needed.
4. Press the RECHARGE button to move the filter
into fast rinse. Again, look for a drain flow rate
about the same as backwash.
5. To return the filter to service, press the RE-
CHARGE button once.
