Noisy Lay-Z-Spa pump

Here is a Troubleshooting Guide and instruction manual which should resolve all issues experienced with all AirJet and HydroJet spas which have become noisy or overly loud.

The issue may be caused by what the spa pump is sat upon.

We would advise to check and ensure the following steps or guidelines are followed on the set up for a Lay-Z-Spa pump:

  • Ensure the pump is located on a flat, hard surface
  • Please ensure foam protection mats are used under the pump
  • Make sure the pump is located away from any walls.
  • Do not place the pump or spa on any gravel or sharp surfaces.
  • Ensure that the pump is not enclosed or boxed in.

Once you have checked these recommendations and are still experiencing the issue please follow these troubleshooting steps:

To solve this issue please follow these steps:

  3. Remove the pump from the spa liner by placing the stopper caps within the spa over the debris screens.
  4. Strike the pump firmly on the side.
  5. This should move the sensor into the correct position.
  6. Plug the spa back in and reset the pump.
