Prerequisites:

  • Poursteady PS1 (3-cup or 5-cup) is fully installed and connected to Wi-Fi

  • Access to my.poursteady.com to edit and verify recipes

  • A digital scale to test measured output

  • Access to the boiler make, model, and settings

  • Ability to safely inspect tubing under the counter


Main Process:

1. Confirm Machine Is Online

  • Go to my.poursteady.com and verify that the device status light is green

  • Attempt to change a recipe and confirm the Poursteady button lights flash

    • This confirms the correct recipe is assigned and active

2. Verify Recipe Configuration

  • Open the current recipe and review the pour volume and pause timing

    • Recommended pour volumes: 20g to 150g

      • Volumes below 20g may not trigger the flow meter

      • Volumes above 150g may overstress the boiler

  • Ensure pause times are set appropriately (5–20 seconds depending on volume)

  • Understand that the flow meter has a ±4% accuracy range

    • A 100g pour may yield 96g–104g in output under normal conditions

3. Run a Flow Rate Test

  • Create a temporary recipe with a 100g pour, no paper filter

  • Place a scale under the nozzle and run the test pour

  • Observe:

    • If the pour is significantly off (outside of 4% range)

    • If any pauses, stops, or sputtering occurs

4. Inspect Physical Installation

  • Check the water line from 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

  • Inspect the Poursteady side panel:

    • Look for air bubbles moving through the lines or stuck in the flow meter

5. Review Boiler Settings

  • Record the following from the boiler:

    • Make and model

    • Set temperature (reduce slightly if overheating is suspected)

    • Serial number

  • High temperature settings may cause steam or vapor bubbles in the water line, disrupting flow

    • Reducing the temperature reduces vaporization risk

6. Clear Overnight Bubbles (if idle)

  • After long idle periods, bubbles may accumulate in the line

  • Run a manual flush (e.g., small 30–50g pour) in the morning to clear the lines


Troubleshooting:

Issue: Inconsistent or Low Pour Volumes

  • Check for incorrect recipe volume or pause times

  • Inspect tubing for air bubbles or pinched lines

  • Ensure the boiler is not overheating or creating vapor pressure

Issue: Flow Stops Mid-Pour

  • Inspect flow meter for debris or blockage

  • Check for accumulated air in the nozzle or tilt axis

  • Reseat or clean tubing as needed

Issue: Flow Discrepancy Between Stations

  • Not applicable: All Poursteady stations share a single flow path

    • Flow issues will affect all stations equally


Success Confirmation:

  • Test pour is within ±4% of recipe volume

  • No sputtering or pauses unless programmed

  • Water line is clear, bubble-free, and unobstructed

  • Boiler temperature is stable, and Poursteady receives water without delay


Escalation:

  • If the issue persists after verifying recipes, boiler settings, and line integrity:

    • Use Intercom to submit:

      • Photos of your recipe settings

      • A video or description of the flow behavior

      • Boiler make/model/serial and current temperature

      • Photos of the tubing path and any visible air bubbles

  • We’ll assist with next steps, including cleaning the flow meter or replacing components
