Please follow these steps:

1. Remove the filter cartridge from the filter housing.
2. To clean the filter cartridge use luke warm water, run the filter cartridge under the water until the water runs clear. Do not use any detergent, washing up liquid or other chemicals. If the filter cartridges are still dirty or starting to disintegrate, change the cartridge for a new one. The filter cartridge must be completely dry before you use this.

If the following steps do not fix the error please move onto step 2.

During the use of the Lay-Z-Spa, the debris screens are used to catch any debris during the filtration system. If the spa is being used in a hard water area, there may be a build up of calcium.

Please follow these steps to resolve this: 

1. Remove the spa pump from the liner, with the stopper caps placed on the inside. Please remove the filter housing first.
2. Empty the spa fully of water.
3. Remove the stopper caps and place a hose on the inside of the spa, up against the debris screen.
4. Complete this for 5 minutes on each debris screen.
5. Use a toothbrush to remove any stubborn debris still lodged.
6. If there is an issue with the calcium build up, we would advise to using ClearWater 1L Scale and Stain Remover to help reduce this and clear the build up.

If after these steps you are still experiencing the E02 error please move onto step 3.

The water flow sensors will not detect the water properly if the water is below the minimum line on the spa liner. To resolve this top your Lay-Z-Spa up with water so the water level is between the minimum and maximum lines.

Please do not fill the spa from a kettle which has been boiled. This may result in your spa liner becoming distorted.

If the following steps do not fix the error please move onto step 4.

This may be due to leaving the stopper caps on the spa liner when operating the pump.

Please follow these steps to resolve this: 

1. Remove the stopper caps
2. Turn the pump off and on at the power supply
3. Press the reset button

If after these steps you are still experiencing the E02 error please move onto step 5.

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

1. Turn the pump off using the On/Off power button on the pump display. Remove the plug from the socket.
2. Remove the pump from the spa liner by placing the stopper caps over the debris screens on the liner.
3. Unscrew the 3 couplings A, B and C.
4. Using a hosepipe, flush water in through the pumps B pipe which should then come out the C.
5. Complete this for about, 2 to 3 minutes.
6. Once this has been completed, switch the water flow from in through the C and out through the B.
7. Once you have completed this for roughly 2 to 3 minutes, re-attach the pump to the liner.

If the following steps do not fix the error please move onto step 6.

During the use of the spa, the washers within the spa couplings may become perished or worn. These are within each of the coupling, A (largest), B and C. To check this please follow these steps:

1. Remove the spa pump from the liner, with the stopper caps placed on the inside.
2. Check the couplings in the 3 pump connections.
3. These couplings can be unscrewed using a small screw driver which will allow these washers to be checked. If these washers are perished or worn, please contact our Customer Care team here who will be able to provide further assistance.

If after these steps you are still experiencing the E02 error please move onto step 7.

During the use of the spa, the warmth of the water expands and contracts the filter housing plastic. If there is a small or invisible crack on the plastic housing, this can cause the E02 error code. However, there may be a blockage in this also which can cause this error code.

To resolve this please follow these steps:

1. Turn the spa off
2. Remove the complete filter housing off the inside of the liner
3. Turn the spa back on, after completing the full reset on the pump and PRCD.
4. Run the spa with the heating and filtration system.
5. If the E02 error code disappears for 2 to 3 hours, the issue is caused by the filter housing black membrane being perished or twisted. This filter housing will need to be replaced if this is the case.

If the following steps do not fix the error please move onto step 8.

On AirJet models during the use of the spa, the warmth of the water can cause manipulation in the pipes of the liner. You may also find the spa liner pipes on initial purchase may be slightly bent due to packaging. These kinks and blockages can cause a restriction of the water flow through the liner. To solve this issue please follow these steps:

1. Remove the spa pump from the liner, with the stopper caps placed on the inside.
2. Check the pipes in the liner.
3. If there is a small bend, kink or debris build up, attempt to manipulate these or clear with warm water. If you are unable to complete this, empty the spa water and air from the liner and use warm water to remove these.

If after these steps you are still experiencing the E02 error please move onto step 9.

Ensure the filters are cleaned after every use, especially if you are using your Lay-Z-Spa daily.
