Symptom
Lay-Z-Spa circulation seems weak; water barely moves at the outlet even though filter mode is on.
Weak Water Circulation
Symptom
Lay-Z-Spa digital temperature display is clearly inaccurate compared to actual water temperature.
Incorrect Temperature Reading
Symptom
Lay-Z-Spa does not heat the water; temperature stays the same or drops even though heater icon is on and no error code is shown.
No Heat with No Error
Symptom
Lay-Z-Spa filter cartridge collapses or deforms quickly, causing frequent flow issues.
Premature Filter Cartridge Failure
Symptom
Lay-Z-Spa filter housing inside the spa keeps popping off or leaking around the threads.
Filter Housing Seal Failure
Symptom
Lay-Z-Spa heater runs but water overheats beyond the set temperature before shutting off.
Overheating / Temperature Overshoot
Symptom
Lay-Z-Spa heater shuts off frequently and will not maintain the set temperature, especially in cold weather.
Inadequate Heating / Heat Loss
Symptom
Lay-Z-Spa hose connections drip or spray water when the pump is running, even after tightening.
Leaking Hose or Adapter
Symptom
Lay-Z-Spa inflatable lid sags into the water and collects rainwater instead of staying firm.
Deflated or Leaking Inflatable Lid
Symptom
Lay-Z-Spa leaks water from around the pump connection area where the hoses meet the liner.
Leak at Pump-to-Liner Connection
Symptom
Lay-Z-Spa leaks water from the bottom or side of the inflatable liner, away from fittings.
Punctured or Split Liner
Symptom
Lay-Z-Spa liner develops bulges or uneven sides when filled and heated.
Deformed Liner Structure
Symptom
Lay-Z-Spa makes loud humming, grinding, or rattling noises during filtration or heating.
Noisy Circulation Pump
Symptom
Lay-Z-Spa powers on but buttons on the control panel do not respond or respond intermittently.
Unresponsive Keypad / Control Panel Failure
Symptom
Lay-Z-Spa pump/heater unit feels excessively hot to the touch on the outside during normal operation.
Overheating Pump Housing
Symptom
Lay-Z-Spa slowly loses air pressure; walls feel soft or saggy over time.
Air Leak in Inflatable Wall
Symptom
Lay-Z-Spa trips the house circuit breaker or RCD as soon as it is plugged in or when heater/bubbles are turned on.
Electrical Short or Ground Fault
Symptom
Lay-Z-Spa water appears cloudy or milky even though the pump and heater work normally.
Cloudy Water / Poor Filtration
Symptom
Lay-Z-Spa water has a strong chemical, musty, or rotten egg smell.
Smelly Water / Contamination
Symptom
Lay-Z-Spa water level drops noticeably over a day or two without obvious external leaks.
Slow Hidden Water Loss
Symptom
Lay-Z-Spa will not power on at all; no lights or display on the control panel.
