Troubleshooting your Heater:
Spa Heaters are the last thing that comes on and is reliant upon all sensors and pressure/flow switches, fuses, pumps and relays working. Heater elements either work or don't work, there is no inbetween, so if you are getting some heat then the issue is probably elsewhere.
Voltage testing to heater: When testing the heater make sure that you have the proper voltage (240 Volts for most heaters) by measuring across the L1 and L2 wires from the Circuit Board to the Heater at the Heater terminals, at the same time, measuring from L1 or L2 to ground does not give a proper reading. Very Important: DO NOT measure by placing your probe on L1 or L2 and the other probe on Ground, you will get a 120 Volt reading which is not correct.
Continuity Test or Ohms test: Turn off the power to the spa and with your probe set to a continuity check, probe the 2 heater terminals at the same time. One probe on one terminal, and the other on the other terminal. Using an Ohm meter, on its lowest setting, measure the resistance between the 2 heater terminals. The typical range is 9-12 Ohms. Note that depending on the heater KW a <25 ohms is acceptable. Another test: With your Ohm meter set to the highest setting, probe one of the heater element terminals and the other probe to the housing (Metal) or Ground. You should get an infinite reading indicating no continuity to ground.
