Is there an E04 error code displaying on your Lay-Z-Spa pump? This means your Lay-Z-Spa pump is experiencing a heating issue and is too hot.

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

Step 1 ‑ Check if pump is overheating:

Please follow these steps to resolve this:

  1. Turn off the pump and remove the plug from the socket.
  2. Leave the hot tub to cool down
  3. Once it has cooled down for 1 to 2 hours, try again.

Step 2 ‑ Check if the pump's thermometer reading is incorrect:

If the above does not solve this, the thermometer reading could be incorrect and a thermal reset is needed.

If your hot tub pump has a thermal reset button on the side

  1. Turn plug off wait 10 seconds and turn on
  2. On the PRCD (black box) press: Reset → Test → Reset
  3. Hold down the On / Off button on the pump for 3 seconds
  4. Press thermal reset button (Side of the pump)
  5. Press heater button - the pump should be working with no error codes

If your hot tub pump does not have a Thermal Reset button

  1. Turn off the pump and disconnect the plug
  2. Wait 10-20 minutes
  3. Reconnect to the mains and turn the plug back on
  4. On the PRCD (black box) press: Reset → Test → Reset
  5. Hold down the On / Off button on the pump for 3 seconds
  6. Press heater button - the pump should be working with no error codes

Step 3 ‑ Is the spa in direct sunlight?

Ensure the hot tub is out of direct sunlight and do not use the pump in over 40°c.

If you experience this error code make sure the full thermal reset steps listed above are completed before the pump is used again.
