Vertical Tub - Low/No Water Flow

A common sign of low water flow is poor cooling performance. If your chiller is not cooling the water, there may be little or no water flow.

If your chiller is cooling normally, water flow is likely sufficient.

Because the return jet is located near the bottom of the tub, you may need to partially drain the water to inspect the flow coming from the jet.

If you do not feel any water flow, or the flow feels weak, please check the following:

 

1. Confirm Both Water Valves Are OPEN

Both water valves located on the hoses must be fully open for proper water circulation.

The valves should be in the OPEN, parallel position (aligned with the plumbing line). See video here and image below for examples of the correct valve position. If one or both valves are perpendicular to the plumbing line, they are CLOSED and will restrict water flow.

2. Check Whether the Unit Is Paused

The button with the ⏯️ Play/Pause symbol and Down Arrow (⬇️) has two functions:

  • ▶️ Pause/Resume the water pump
  • Lower the temperature (only after entering temperature adjustment mode)

If the pump is paused, water circulation will stop.

To check if the unit is paused:

  • 🔴 A flashing red indicator light means the pump is paused.
  • No flashing light means the pump is operating normally.

To resume water flow:

  • ▶️ Press the Play/Pause button once.
  • ✅ The flashing red light should turn off and water flow should resume.

⚠️ Important: To adjust the temperature, you must first hold the SET button for 3 seconds. If SET has not been activated, pressing the button will only pause or resume the 

3. Confirm You Have Changed the Filter Recently

A dirty or clogged filter can reduce water flow.

If you have not changed the filter within the last month, we recommend replacing it first and then checking whether water flow improves.

4. Check the Jet Pressure Inside the Tub

Ensure water is flowing from the jet inside the tub.

  • If water is flowing from the jet, the pump is operating properly.
  • If there is little or no water flow, drain the tub so the water level is approximately 1 inch below the jet and take a video showing the flow coming from the jet.
