Water Softener: Water meter isn't working
Check the bypass valve to see if it's in the bypass position; the water flow meter won’t detect any water flow if the water softener is bypassed. If the water softener isn’t bypassed, then it’s likely the water flow meter is defective.
These repairs may help solve your Water Softener problem:
Replace the water softener water flow meter
The water flow meter measures water usage. A defective water flow meter won’t detect water flow. Replace the water flow meter if it won’t detect water flow when water moves through the softener.
Replace the water softener timer
The timer is an electronic control board that lets you program the water softener. The timer also controls the functions such as water softening and flushing the resin filter. Replace the timer if it fails to control the water softener’s functions.
