Safety guidelines for using Craftsman water treatment products

• Read all procedures, guidelines and maintenance steps in the owner's manual and installation guide carefully before installing and using the water treatment equipment.
• Don't attempt to use the water treatment equipment to make safe drinking water from non-potable water sources.
• Don't use the water treatment system on microbiologically unsafe water or water of unknown quality.
• Check with your local public works department for plumbing and sanitation codes and follow all local code.

How to fix your Craftsman water treatment equipment when its flow meter isn't working

A broken water flow meter or faulty timer can prevent the display from showing water usage. Also, the water flow meter won't detect any water flow if the water treatment equipment is bypassed.

Check the bypass valve position first when the control isn't displaying water flow. Move the bypass valve to the service position to send water through the treatment equipment if you find the valve in the bypass position.

If the water treatment equipment isn't bypassed, then the water flow meter could be stuck or broken. Check water flow using the diagnostic test cycle as described in the owner's manual. If the water flow meter fails to detect water flow in the diagnostic test cycle, then the water flow meter's turbine could be jammed or broken. Unplug the water treatment equipment and shut off the water supply to the system. Pull off the bypass valve assembly to access the water flow meter turbine. Inspect the turbine and replace it if it's jammed or broken.

If the water flow meter turbine is okay, check the wire harness for damage between the flow meter's sensor and the timer and replace the wire harness if damaged.

If the flow meter's wire harness is okay, then a faulty flow meter sensor or a failed timer is preventing the display from showing water flow. There's no way to test the flow meter sensor so you won't be able to determine whether the sensor or the timer is at fault. Replace the sensor because it costs less than the timer. If the timer still doesn't detect water flow after replacing the flow meter sensor, replace the timer.
