E10

Is there an E10 error code displaying on your Lay-Z-Spa pump? This is a high salt alarm which features only on HydroJet models. This alarm is visible if there has been too much salt added to the spa or a large amount of water has evaporated.

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


Step 1 - Drain 20% of the spa and re-fill with fresh water:

  1. Do not use the spa or place any further pure spa salts for 24 to 48 hours to ensure the levels reduce.
  2. Unplug the spa pump.
  3. Remove from the liner and drain 20% of the water from the spa. Refill this with fresh water.
  4. Start the Salt Chlorinator System.

What salt to use:

  • Pure Spa Salt is the only salt which is suitable for use in the spa. This can be purchased on either Amazon or eBay.
  • Ensure Pure Spa Salt does not contain anti-caking agents.
  • Place 2kg of Pure Spa Salt on initial set up.
  • Pure spa salt is required alongside chlorine.



Step 2 - Follow salt chlorinator function instructions:

Instructions of salt chlorinator function:

To use the Salt Chlorinator System, please add Pure Spa Salt to the water using the following steps:

  1. Turn the spa on, using the reset procedure found below:

  3. Ensure the Salt Chlorinator System is turned off.
  4. Add gradually 2kg of Pure Spa Salt to the spa, please ensure the salt is completely dissolved and dispersed into the spa effectively.
  5. Once the salt has fully dissolved, switch on the Salt Chlorinator System and set the working duration for the system.
  6. This system can be set from 3 hours, 5 hours or 8 hours.
  7. We would advise to attach the spa cover during the Salt Chlorinator process.

Key points when using this function:

These are points which have to be considered and followed once using this function:

  1. Always use Pure Spa Salt, using only sodium chloride (NaCI) salt.
  2. This has to be 99.9% pure or water conditioning salt pellets.
  3. Pure Spa Salt has to be used in conjunction with chlorine.
    • The reason for the Pure Spa Salt is to reduce the amount of chlorine required in the spa but not alleviate this altogether.
    • Chlorine will also be required in the spa however at a reduced volume.
  4. Pure Spa Salts should last roughly 1 month within the spa water.
  5. After this period of time, the water and Pure Spa Salt will need to be changed and refilled. This will require another 2 kg of salt placed in the spa.
  6. If the spa is not being used, the Chlorinator Function will need to be run for 3 hours a day.
  7. If the spa is being used, the Chlorinator Function will need to be run between 5 and 8 hours a day.
  8. It is possible to switch to using the Chlorine Granules that are in the Chemical Starter Kit, or Chlorine Tablets so that you are able to use the standard test strips.
