Why is there no soft water from my A.O. Smith AO-WH-SOFT-350C?
- S

  Several factors could be the reason for no soft water. First, check that the bypass valve is in the service position. Second, ensure the appliance is plumbed correctly. If there was an extended power outage, reset the time and regenerate the unit. Also, your water hardness might have increased, so re-test the water and enter a new setting. Finally, the unit may not be metering water. Flow should be indicated with water usage.

What to do if A.O. Smith AO-WH-SOFT-350C has no soft water after regeneration?

  If you're not getting soft water after regeneration, here's what to check: Ensure there is salt in the brine cabinet. Check for sediment in the brine cabinet that may have plugged the brine line and air check/draw tube and flush clean. Also, the flow control could be plugged, so clear any debris. Make sure the drain line isn't pinched, frozen, or restricted. A clogged injector assembly can also be the culprit—clean the nozzle and throat. Finally, a salt bridge may have formed; dislodge it with a blunt object or hot water.

  If your water dispenser indicates flow even when water isn't being used, it could be due to a few reasons. The most common cause is a leak in the household plumbing system, so check for and repair any leaks. Also, make sure the electric cord is plugged in and that there is power at the outlet. Finally, the transformer might be defective, test it with a voltmeter and replace if necessary.

What to do if no flow is indicated when water is flowing in A.O. Smith AO-WH-SOFT-350C?

  If no flow is indicated when water is flowing, first ensure that the Bypass Valve is in the Service position. Also, check that the appliance is plumbed correctly. The sensor may not be receiving a signal from the magnet on the turbine, so remove the sensor and test it with a magnet. If flow is indicated during the test, check the turbine. If not, replace the sensor. Finally, the turbine itself might be jammed, so remove the Bypass Valve and clear any debris from the turbine.

How to fix excess water in brine tank of A.O. Smith Water Dispenser?
- M
  Michael Robertson PhDAug 26, 2025
  Excess water in the brine tank can be caused by a restricted, frozen, or pinched drain line; remove the restriction, thaw, or straighten the line. It can also be due to a plugged brine line, brine line flow control, or air check/draw tube; clean these components and remove any sediment from the brine cabinet. Lastly, a plugged injector assembly can cause this issue; clean or replace the injector.

Why does my A.O. Smith Water Dispenser stay in regeneration?

  If the appliance stays in regeneration, first make sure the controller is properly attached to the cover plate. A defective magnet disk could also be the cause, so replace it. Check for any foreign objects in the main control valve and remove them. Finally, a broken valve assembly could be the issue; in this case, repair the valve assembly.

Why does my A.O. Smith Water Dispenser produce salty water?
- L
  Lauren CollinsNov 14, 2025
  Salty water can result from several issues. A plugged injector can cause this, so replace the injector screen, nozzle, and throat. Low water pressure (below 30 psi) can also be a factor. Check for and remove any restrictions in the drain line, flow control, or brine line. Make sure there isn't too much water in the brine cabinet and verify the correct water level relative to the salt setting. Address intermittent pressure drops by installing a check valve on the inlet water line. Clean the brine valve housing if the brine valve drips water back to the brine tank. If 'Home not found', cycle power by unplugging and replugging the transformer. For a 'Motor error', replug all wires in this sequence: motor, sensor, and power cord, then cycle power. For a 'Home offset', cycle power to reset. If ...
