Prerequisites

  • External Water filter is inspected and cleaned of any debris unwanted material.

  • System is safely shut down and depressurized

  • Tools:

    • T10 Torque screwdriver

    • Wrench

Safety note: Always confirm that the Poursteady is powered off, disconnected from water, depressurized, and drained before removing parts

Diagnosed Issues

  • The Poursteady continually pours water without a recipe being active

  • The Poursteady has a drip at the nozzle without a recipe being active

  • The Poursteady has a bubble forming at the nozzle without a recipe being active

  • The Poursteady is not pouring water when a recipe is active

Main process

  1. Disconnect from Power: Turn off power and disconnect the power plug from the Poursteady
    ​

  2. Disconnect the Poursteady from water

    1. Turn off water and disconnect the Poursteady from water by removing the water line that directly enters the Poursteady.

  3. Depressurize and Drain the Poursteady:

  4. Free the valve by removing bracket screws

    1. Use the T10 torque screwdriver to remove the two screws on the valve bracket. This allows the valve to move freely for the next steps. Keep the screws in a safe place for reassembly.

  5. Remove the retaining nut

    1. Use the wrench to remove the retaining nut securing the magnetized block. Apply slight force and avoid twisting nearby fittings. Once removed, set the nut (and any washer) aside in the order they came off.

      ​

  6. Slide off the electro-magnetized block

    1. Carefully slide off the magnetized block once the retaining hardware is removed.
      ​

  7. Remove the piston from the valve head

    1. Readjust the bracket back against the end plate and hold it in place with your thumb. This creates leverage and stability for removing the piston. Keep the valve aligned so you’re not stressing the body or fittings.
      ​

    2. Using the wrench, remove the piston (this may require extra effort). Maintain firm leverage with the bracket/end plate support while turning. Once removed, inspect the piston for scoring, damage, or debris stuck to sealing surfaces.
      ​
      ​

  8. Inspect and clean debris inside the valve

    1. Look inside the valve for debris preventing the piston from closing fully. Remove any visible particles carefully so you don’t scratch internal surfaces. If debris is significant, note what it is (sand, scale, fragments) for troubleshooting upstream filtration.
      ​
      ​

  9. Reinstall the piston (tight and secure)

    1. Screw the piston back in and ensure it is tight and secure to prevent leaks when lines are restored. Do not overtighten beyond your internal spec; use controlled force. Confirm the piston moves/threads smoothly and seats properly.
      ​

  10. Reinstall the magnetized block and retaining hardware

    1. Slide the magnetized block back into position. Reinstall the retaining washer and nut, tightening until secure. Double-check that the block is seated straight and not pinched or misaligned.

  11. Verify the regulator outlet fitting is properly set

    1. Before reinstalling the bracket, confirm the outlet fitting on top of the regulator was not loosened while the valve was moved back and forth. You should see 4x taped threads exposed from the regulator. If it shifted, re-seat and tighten it to the proper position. This step helps prevent leaks and misrouting issues.
      ​

  12. Reattach the bracket

    1. Use the torque screwdriver to reinstall the bracket.
      ​

  13. Perform a line blowout (purge air and debris):

    1. Run the line output into a sink or bucket for 1–2 minutes. This clears air bubbles and flushes remaining debris that may have caused the piston obstruction.

  14. If the issue still persists, you may need to clip hose clamps and clean valve from the inlet/outlet
