Troubleshooting the CWS Plus Sediment Filter
One problem that may occur is if you do not have enough backwash flow rate to properly clean the
Sediment filter. You can verify the backwash flow rate by running the drain line into a bucket and timing
it when the CWS Plus is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 5 gallons per
minute and a 2.5 cubic foot system should have 10 gallons per minute of backwash.
In some cases, the CWS Plus may not be programmed correctly. See the CWS Plus service manual for
instructions on how to access the master programming.
What to Do If Your Filter Tank Does Not Sit Level on the Floor
Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become
crooked during shipment. If you find that that your tank does not sit level on the floor, you can easily
adjust it by holding the empty tank and rapping it on a concrete or solid floor once or twice in order to
level it.
How To Remove Media From Control Head
Sometimes, when doing the Initial Backwash, the media gets lifted up into the control head. You can
tell this happened because you will have little or no flow, either going out to drain while in the backwash
positon, or when in the service positon.
To remove media from a control head, do the following:
1) Put the Inlet Bypass in the Closed position.
2) From the Service Mode, initiate a manual regeneration, by pressing and holding the regen button
(button on far left).
3) The valve will advance to the BW (backwash) position, and start counting down. Press the Regen
button again, and wait for the valve to advance and stop at the Rapid Rinse (RR) position.
4) With the valve in the RR position, open and close the Inlet Bypass valve several times. After the third
or fourth time, leave it in the open position and check the drain line- do you have a good solid flow?
90% of the time, the answer is yes, but sometimes, even after opening and closing the valve many times,
you still don’t have good flow… But, in either case (good or no flow), continue…
5) With the Inlet Valve OFF, Advance the valve back to Service position again, and again press and hold
the Regen button, we are putting the valve back to the Backwash position.
6) Open the Inlet valve just enough so you can hear the water passing thru the valve- you should notice
a corresponding slow flow out of the drain line. After a minute, if there are no air bubbles present, open
the valve about another quarter inch- again, you should see a corresponding increase in the flow… And
you will continue until the valve is full open.
