3. Identifying the Components:

  • Once the back panel is removed, you’ll find the pressure sensor, water valves, and spray nozzle.
  • The pressure sensor is responsible for detecting water frequency changes and relaying the information to the main control board.

4. Testing the Water Valves:

  • Set your washing machine to the rinse and spin cycle, which typically uses cold water.
  • Use a voltage meter to check the voltage on the cold water valve; it should show the correct voltage.
  • Repeat the process by selecting the heavy-duty cycle and hot water to check the voltage on the hot water valve.

5. Removing and Inspecting the Water Valve:

  • Ensure the power is turned off and unplugged before proceeding.
  • Wait for 10-15 seconds to allow the capacitors to discharge.
  • Loosen the screw on the control panel side, flip the control panel up, and take a picture of the valve’s connections for reference.
  • Locate and remove the three screws that secure the water valve in place.
  • Disconnect the two hoses attached to the pre-wash and bleach dispenser, and remove the valve for inspection.

6. Inspecting and Reinstalling the Water Valve:

  • Inspect the removed water valve for any blockages or issues.
  • If necessary, replace the entire assembly for a quicker and easier fix.
  • When reinstalling the valve, refer to the reference pictures taken earlier to ensure correct hose connections.
  • Tighten the screws securely, taking care not to over-torque them due to the presence of plastic components.

7. Reassembling and Testing:

Frequently Asked Questions:

Can I clean the inline filters myself?

Yes, you can clean the inline filters by inspecting them for any blockages or debris and rinsing them under running water if necessary.
