Not Filtering

Here is a troubleshooting guide that should help to diagnose any filtering issue you are experiencing with a Lay-Z-Spa.

 

Step 1 - Check if filter cartridges are dirty or perished

Please follow these steps:

1. Remove the filter cartridges
2. Check them for any dirt or dissolved parts.
3. Always make sure the cartridge is clean and dry when you replace them.
4. You should ideally change or clean the filter cartridge after every use.

Step 2 - Check if the filter housing is disrupting the water flow 

Please follow these steps:

1. Remove the filter housing and check the black membrane inside is not perished or bent.
2. Try running the hot tub without this attached and see if water flows correctly. You may need to replace the filter housing.

Step 3 - Check if the debris screens and pipework are blocked 

Please follow these steps:

1. Remove the pump and check the pipework in to the liner for any blockages. You should be able to see all the way to the debris screen.
2. The debris screen can be cleared with a toothbrush or toothpick. On the newer Lay-Z-Spa hot tubs you are able to remove the top debris screen for cleaning.

Step 4 - The pump unit might need cleaning 

To clear the pump and the pipework internally you need to complete the backwash procedure:

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.
