Note: When testing this heater if it trips the breaker simply unplug it and if the breaker stays on plug back in and if it trips this heater is the cause if it is not a breaker trip issue then measure between the two terminals with an Ohm meter it should measure about 10.5K ohms. If it measures 0K it is open. If it is not tripping the breaker and doesn't measure open then the heater is not bad look for other issues that cause no heat Like a Pressure Switch, Stopped up filter, No water movement, Open circuit on board etc…..
On this particular heater the pressure switch is included and it can cause a no heat condition and can be purchased separately.
