Description Cause Solution
Water Flow Error The stopper caps are still inside the spa. Remove the black stopper caps from the inside of the liner before heating, filtering or running the bubbles on the spa. If you are unsure how to remove them, please refer to the assembly section within the Lay-Z-Spa owners manual.
Filter cartridges are dirty Remove the filter cartridge from the filter housing and check it is clean. Please make sure the new filter is clean and dry before you install it.
Filter housing is restricting flow Remove the filter housing from the liner and check the black membrane inside. These should lie flat inside the housing. If they are ok, continue to run the spa without the filter cartridge attached and see if the error code persists.
Ensure that the debris screens are clear of debris.
Pipes within the liner are kinked or bent. Disconnect the pump and check the pipes inside the liner. You can manipulate these with warm water to return them to the correct shape.
Washers perished inside pump couplings Disconnect the pump from the liner. Check the condition of washers inside the couplings on the pump. We would suggest backwashing the pump to clear any debris. If the washers are perished you can purchase spares from the Lay-Z-Spa website here

Description Cause Solution
Not grounded/earthed correctly An issue with your power supply Remove any extension leads, we do not recommend the pump is run on one of these. Also try the pump in an alternative socket. If the issue persists, please contact us for further advice.

Backwash Procedure

Attach the stopper caps to the inside of the liner and then remove the Lay-Z-Spa pump unit from the liner (you can do this by unscrewing the 3 couplings ‘A, B and C’).

Using a hosepipe, flush water backwards through the pump. Water should go through pipe ‘B’ and come out of pipe ‘C’.

After a few minutes, flush the water in the opposite direction for about 2 minutes (through pipe ‘C’ and out of pipe ‘B’).

If you have a Hydro Jet Lay-Z-Spa, unfortunately, the backwash procedure will be a little tricky. These are not constructed like the other models of the Lay-Z-Spa. please contact us

Leaking Pump

Leaking from the bottom of the unit

← swipe →

Reason Solution
This can be caused by a perished washer, cracked pipe or other issue inside the pump. Attach the stopper caps to the liner. Remove the pump and check the pipework is clear and clean. Double check any washers to make sure they are not perished inside the couplings. Whilst the pump is disconnected check the liner air pipe for any leaks. There will be some water lost from this pipe but this is normal and can be stopped by adding the grey cap. If the water appears to be creating a puddle underneath just the pump please contact us. Leaking from coupling/Pipes

← swipe →

Reason Solution
Check that the couplings are fully secured and not cross threaded or cracked. Check that the washers are lined up correctly. They may also be perished which means the connections are not sealed. Please find replacement parts at the following link here
Washers may be misaligned. Check that the washers are lined up correctly.

 

Heating Issues

There may be a number of reasons why your Lay-Z-Spa is experiencing heating problems. The following is a list of common problems, reasons and solutions.
← swipe →

Reason Solution
The spa is not heating to the correct temperature.
  • Watch the Thermal Reset Video
  • Turn the pump unit on at the mains.
  • Press the test button once and leave it bleeping (leave for 10 seconds).
  • Turn the pump unit off and unplug from the socket (leave for 10 seconds).
  • Plug the pump unit back in and turn it back on.
  • Press the thermal reset button using a pencil or screwdriver.
  • Once done, press the heater button. Your pump should now be working.
There is debris inside the pump which is stopping the water from heating properly. Try the back wash procedure.
The incorrect temperature has been set on the pump. Use the arrow keys on the control panel to adjust the spa temperature. The pump display will show current temperature of the water in your spa and not the set temperature.
The spa is heating to a higher temperature than the temperature that you set. This is a perfectly normal function. The pump unit heats the water to a couple of degrees higher than the temperature that you set. It will then stop heating the water and monitor the temperature until it has dropped to a few degrees lower than the temperature that you set.

*Please note the pump will heat the water 1-1.5 degrees per hour. It may take up to 24 hours to heat the water from cold depending on the ambient temperature outside.

Power & Electrical Faults

No power to the pump

Reason Solution
Normally caused by an electrical issue Check the RCD plug and fuses. Try plugging into an alternative socket.
Extension lead in use Ensure that the pump is plugged into an earthed mains socket and not an extension lead.

Tripping the electrics

Reason Solution
Pump switching off or electrical issue. Also check the RCD and plug fuses.

Not Filtering

There are a number of reasons why your pump may not be filtering water correctly. The following are a list of reasons and how to potentially solve them.
← swipe →

Reason Solution
Filter cartridges could be dirty or perished Remove the filter cartridges and check them for any dirt or dissolved parts. Always make sure the cartridge is clean and dry when you replace them. You should change the filter cartridge after every use of the spa.
The filter housing could be disrupting the water flow Remove the filter housing from the spa and check the black membrane inside is not perished or bent. Try running the spa without this attached and see if the filter works correctly. You may need to replace the filter housing.
The debris screens and pipework could be blocked Remove the pump and check the pipework in to the liner for any blockages. You should be able to see all they way to the debris screen. The debris screen can be cleared with a toothbrush or toothpick. The newer models of spa can remove the top debris screen for cleaning.
The pump unit needs cleaning Try the backwash procedure to clear the pump and clean the pipework internally.

Massage Function or HydroJets Not Working Properly

← swipe →

Reason Solution
Massage seam not working Place the stopper caps on the liner and remove the pump. Press the air button on the pump and check if any air flows from the air pipe. If there is no flow please contact us.
Check for any tears or splits along the seam which is disrupting the flow. Please note we do not suggest putting the bubbles on when the lid and top cover are on the spa, this can cause a pressure build up in the massage seam causing it to split. Also be aware that standing on the filter housing can cause damage to the liner as well.
HydroJets not working Remove the jets from the liner and check each one for any debris. This will also remove any air locks created behind the jet. When you place the jet back into the liner be sure to screw it all the way round and click it into place. Make sure the jets are fully open before you use the HydroJet system again. Please see the manual for more details on installing the jets.
