Troubleshooting Your Spa Heater
Spa heaters and elements can be classified into 2 common categories mechanical failure and non mechanical failure.
Mechanical failure: When an element has the proper voltage (120 volts or 240 volts) but, does not have the ability to heat the water passing through the heater assembly. This type of failure indicates that the filament that actually does the work of heating the water is no longer in one piece. A mechanical failure will be covered under the manufactures warranty the majority of the time.
Non-Mechanical failure: When an element has the proper voltage (120 volts or 240 volts) but, causes a ground fault. A ground fault is when the GFCI breaker trips. This type of failure indicates that the sheathing is allowing the voltage to seep into the water causing the ground fault. The most common causes of this type of failure is chemical damage, dry firing, incorrect installation, etc… A Non-Mechanical failure will not be covered under the manufactures warranty the majority of the time.
When measuring your spa heater make sure you measure correctly to ensure that you order exactly what you need
Select a coating Regular, Tefel, Teflon, Titanium (a special coating is not required when selecting your new heater element the benefits are for those who have hard water, well water, use a water softener and/or those who don't test there chemical levels as often as they would like to)
We recommend replacing the gaskets (1.5" or 2" o-ring gaskets) on your heater assembly tube when changing or replacing your heater element (reason for this, if your heater element stopped working either due to chemical damage or long term use imagine what your gaskets have been through)
