Is there an E03 error code displaying on your Lay-Z-Spa pump? This means the ambient air temperature is too low.

We recommend following these troubleshooting steps to get back in your Lay-Z-Spa in no time.


Step 1 - Check if the pump is too cold:

  1. Remove the pump from the spa by placing the stopper caps on the inside of the spa over the debris screens.
  2. Carry the spa pump indoors or to a warmer place.
  3. Leave this within a warm area for 2 to 3 hours for the internal parts to warm up.
  4. Once the spa pump has warmed up, the error code should disappear.
  5. Please ensure the full reset procedure is completed before re-using the spa and make sure the stopper caps have been removed from the inside of the spa liner before the spa pump has been used.
