Immersion Heater Tripping Breaker? How to Test the Element & Insulation

Is your electric water heater tripping the consumer unit or RCD? Before you go out and buy a new element, you need to troubleshoot the fault. In this video, I show you how to safely test an immersion heater using a multimeter to see if the element is actually the problem. We walk through: Safety First: How to verify the power is fully isolated before touching any terminals. Continuity Test: Checking the Ohms (Ω) reading to ensure the element isn't "open circuit." Insulation Resistance: Testing for a "leak to earth" to see if the element is shorting out against the body of the unit. In this specific case, the readings (19 Ohms and high insulation resistance) show the element is actually healthy—meaning the fault lies elsewhere in the circuit!
