PS1 - Water Not Dispensing / Under Pouring, Low Flow Rate

Use this guide to diagnose and resolve a PS1 Poursteady that is not dispensing any water, under pouring, or has low flow rate / pressure. Follow each section in order before moving to the next.

Step 1: Check Boiler Settings and Water Lines

Before testing any components, confirm the basics:

  • Verify the boiler is configured correctly and is working.

  • Check the water line from the boiler to Poursteady:

    • Ensure the line is as short and direct as possible

    • Lightly massage any compressed areas in the tubing to relieve flow restrictions

    • Look for kinks, bends, or obstructions under the counter


|If both look good, proceed to voltage testing.

Step 2: Test Valve and PCB

You will need a voltage meter with prongs for this step.

  1. Put your finger on the pour valve (top right) and press any button to activate a pour. You should hear and feel a click

  2. Slide the terminals on the valve slightly forward to access them.

  3. Place your prongs on the terminals.
    ​

  4. Press any button on your Poursteady to send an electrical charge to the valve (this opens it).

  5. Read the voltage — you should see 23–24 volts DC.

If you see low/no voltage at the valve terminals:

Test directly at the main PCB instead:

  • Follow the wire from valve to the bottom Molex connector and test there leads (negative on the left, positive on the right).
    ​

  • Press any button on the Poursteady to open the valve.

  • You should still read 23–24 volts DC

If voltage readings are normal, continue to Step 3. If there is still low/no voltage at the PCB, contact support.

Step 3: Visual Inspect for Debris in the Lines

First, depressurize and drain the Poursteady. THIS STEP IS NECESSARY TO PREVENT DAMAGE / WATER SCOLDING

(SEE INSTRUCTIONS ON DEPRESSURIZING AND DRAINING)

  1. Flow meter — Look at both the inlet and outlet sides for any visible debris.
    ​


    ​

  2. T-tube restrictor — This is the most common locations for debris buildup.
    ​

Step 4: Disassemble and Inspect the Valve / Restrictor

To access the T-tube restrictor and valve internals:

  1. Unscrew the two screws on top of the valve so the valve can move freely downward.
    ​

  2. Using Tube pilars, slide the tube clamp off the valve to the left to expose the restrictor. Inspect and clear any debris.
    ​

  3. Remove the tube on the right side

  4. Loosen and remove the bottom nut on the valve.
    ​

  5. Slide off the main block.

  6. Loosen the solenoid to access and inspect inside the valve head.
    ​


    ​

  7. Clear out any debris blocking the valve head.
    ​

  8. Reassemble all components in reverse order. Make sure everything is tightened to prevent water leaking

  9. Ensure the Valve Head has the #1 orientated to the left (facing the terminals) for proper flow

Step 5: Disassemble and Inspect the Flowmeter

To access the T-tube restrictor and valve internals:

  1. Unscrew the three screws on top of the flow meter
    ​


    ​

  2. Remove the top of the flowmeter

  3. Inspect the inside of the flowmeter to clean out the debris
    ​


    ​

  4. Ensure that the internal propeller can move freely and smoothly
    ​


    ​

  5. Reassemble all components in reverse order. Make sure everything is tightened to prevent water from leaking

Step 6: Retest

Once everything is clean:

  1. Reconnect the boiler communication cable.

  2. Plug in power.

  3. Run a test to check if water flows normally.
