Why is there no soft water coming from my AQUAPHOR S550?
- D
  Daniel TylerAug 9, 2025
  If your AQUAPHOR Water Dispenser isn't dispensing soft water, possible causes include: * The bypass valve is in the Bypass position or not fully in the Service position. Set the bypass valve to the normal Service operation. * The device is connected to the water supply incorrectly. Check the connection to ensure it is correct. * There was a prolonged power failure. Reset the current time. * The water consumption isn't being tracked. Check if the water consumption indicator on the softener works when water is drawn. If not, further inspection is needed. * The source water composition has changed. Analyze the water and adjust the settings accordingly. * The source water is mixed with purified water. Ensure there is no mixing of source water.

What to do if there is excess water in the brine tank of my AQUAPHOR Water Dispenser?
- T
  Thomas KellerAug 15, 2025
  If you notice excess water in the brine tank of your AQUAPHOR Water Dispenser, it could be due to: * A clogged, kinked, or frozen drain line. Remove the blockage and straighten any kinks in the drain line. * A clogged brine line, brine line flow restrictor, or air check valve. Clean these components and remove any dirt from the salt tank. * A clogged injector. Clean or replace the injector, and if the injector neck has been removed, replace it with a new one.

Why is there no display on my AQUAPHOR S550?

  Scott HubbardAug 20, 2025
  If the display on your AQUAPHOR Water Dispenser is blank, consider these potential causes: * The power wire may not be connected. Ensure the power supply is properly connected. * There might be no mains power. Check the outlet for power. * The power supply could be faulty. Use a voltmeter to check the power supply (should be 12 VAC). If it's less than 10 VAC, check the voltage at the 220 VAC outlet. * The controller might be faulty. If 12 VAC is reaching the controller, consider replacing it. * The ambient temperature might be too high. If the air temperature is +38 °C or higher, the display won't show characters, though the controller's functionality remains intact. Lowering the temperature is the only solution.

  If your AQUAPHOR Water Dispenser remains stuck in regeneration mode, it could be due to: * Incorrectly installed controller. Ensure the controller is correctly fixed on the screw mechanism cover. * Defective magnetic arm. Replace the magnetic arm. * Foreign object in the control valve mechanism. Disassemble the valve and remove any foreign object. * The control valve is out of order, and the engine is running. Repair or replace the control valve.

Why does my AQUAPHOR Water Dispenser sensor show water flow when there is no water flowing?
- C
  Cody BradleyAug 29, 2025
  If the sensor of your AQUAPHOR Water Dispenser registers water flow even when water is not running, it is likely due to a water leak after the softener. You should fix the leak to resolve this issue.

Why is my AQUAPHOR S550 not producing soft water after regeneration?
- S
  Sharon HayesNov 4, 2025
  If your AQUAPHOR Water Dispenser isn't producing soft water after regeneration, here's what might be happening: * The brine tank may be empty. Add salt to the tank. * There might be a clog in the brine line, brine valve, air check valve, or injector due to solids. Dismantle the brine line with the air cut-off valve and air check, then rinse with clean water. Also, clean the brine valve and injector, and remove any impurities from the salt tank. * The brine line flow restrictor could be clogged or improperly installed. Dismantle the brine valve, then clean and correctly install the salt flow restrictor. * The drain line might be kinked, frozen, or clogged. Straighten the line, allow it to thaw, or clear the clog. * The injector may be clogged. Remove the injector cap, clean the n...
