E01

Is there an E01 error code displaying on your Lay-Z-Spa pump? This means your Lay-Z-Spa pump is experiencing a water sensor issue.

We recommend following these troubleshooting steps until the error code stops displaying. Then you'll be back in your Lay‑Z‑Spa in no time.


Step 1 ‑ Check water flow sensors

This error is caused if the water flow sensors are not in the correct position. Please follow these steps to resolve this, making sure you leave 10 seconds between each step:
  1. Turn the pump off using the On/Off power button on the pump display. Remove the plug from the socket.
  2. A) On external pumps - remove the pump from the spa liner by placing the stopper caps over the debris screens inside the spa. (You will need to remove the filter housing first).
    B) On built-in UltraFit pumps, step 2 is not needed.
  3. Strike the pump firmly on the side.
  4. This should move the sensor into the correct position
  5. Plug the spa back in and reset the pump.

Please note: Do not hit the pump on either the top or bottom of the unit.

If this does not resolve the issue please move onto step 2 below.

Step 2 ‑ Check for debris build up

Another cause of this error code is a debris buildup within the pump. To resolve this, please follow the backwash procedure steps here:
