Description Cause Solution
Not grounded/earthed correctly. An issue with your extension lead or power supply.

Remove extension lead or get a qualified electrician to check your socket & power supply. If this does not resolve the issue, please contact us.

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

Noisy Pump

← swipe →

Description Cause Solution
Water Flow Sensor Error Water flow sensors in the pump cause it to become noisy or overly loud.
  • Turn the pump off using the On/Off power button on the pump display.
  • Move to the power supply, turn the power off and remove this from the socket.
  • Remove the pump from the spa liner by placing the stopper caps within the spa over the debris screens.
  • Strike the pump firmly on the side. This should move the sensor into the correct position.
  • Plug the spa back in and reset the pump.
Water Flow Sensor Error Water flow sensors become stuck or flipped over.
  • Turn the pump off using the On/Off power button on the pump display.
  • Move to the power supply, turn the power off and remove this from the socket.
  • Remove the pump from the spa liner by placing the stopper caps within the spa over the debris screens.
  • Unscrew the 3 couplings A, B and C.
  • Using a hosepipe, flush water in through the pumps B pipe which should then come out the C.
  • Complete this for about, 2 to 3 minutes.
  • Once this has been completed, switch the water flow from in through the C and out again through the B.
  • Once you have completed this for roughly 2 to 3 minutes re-attach the pump to the liner.

Leaking Pump

Leaking from the bottom of the unit

← swipe →

Reason Solution
Normally caused by a part inside the pump being faulty or broken. Attach the stopper caps to the inside of the liner, disconnect the pump unit, and move the pump unit away from the liner for approximately 10 minutes. If no more water has appeared beneath the liner, then the pump is the problem and may need replacing.

Leaking from coupling/Pipes

← swipe →

Reason Solution
Couplings may not be attached correctly. Check that the couplings are fully secured and aligned.
Washers may be misaligned. Check that the washers are lined up correctly.

You may need to confirm whether the pump or the liner are behind the problem, rather than the couplings or pipes. Attach the stopper caps to the inside of the liner, disconnect the pump, and move the pump away from the liner for 10 minutes. If no more water has appeared beneath the liner, then the pump is the problem and may need replacing.

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 (see Owner’s Manual for location).
  • 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 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.

Power & Electrical Faults

No power to the pump

← swipe →

Reason Solution
Normally caused by an electrical issue. Check the RCD plug and fuses. Try plugging into an alternative socket. If the problem persists, your pump will need to be replaced.
Can be caused if the pump unit is plugged into an extension lead. Ensure that the pump is plugged into a mains socket and not an extension lead.

Tripping the electrics

Reason Solution
Tripping the electrics can be caused by plugging the pump into an extension lead. Ensure the pump unit is plugged into a mains socket and not an extension lead.

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
Filters are causing the problem. Remove the filters from the filter housing and try running the spa without them. If the water is flowing freely, then the filters are the problem and will need to be replaced.
Filter housing is causing the problem. Remove the filter housing from the spa and try running the spa without the filter housing and filters. If the problem is resolved, then the filter housing is the problem and will need to be replaced.
Debris screens are blocked. Check that the debris screens are clear of debris. If they are blocked with debris, thoroughly wash them out.
Pipes within the liner are kinked or bent. Although this is a very rare occurrence, the pipes within the liner could be kinked or bent. This will reduce the air flow and create a filtering problem (causing the E02 error to appear). Using your hands, check the condition of the pipes within the liner.
Pump unit needs to be cleaned. Try the back wash procedure.

Massage Function or Hydro Jets Not Working Properly

Reason Solution
Pump may be too cold. Attach the stopper caps to the inside of the liner, disconnect the pump unit, and bring the pump unit inside to warm up.
Pump may be too hot. Attach the stopper caps to the inside of the liner, disconnect the pump unit, and bring the pump unit inside to cool down.
Pump may be broken. Go through the checklist guide. If checks do not resolve the problem, your pump may need replacing.
