How to check (ring out) the heating element of a boiler or water heater
Checking the heating element without removing it from the water heater (boiler).
✔️ Algorithm for checking the integrity of the heating element's nichrome filament:
👉 Set the multimeter to continuity mode and touch the probes to the contact pins. If the heating element's filament is intact, you'll hear a "circuit sound" - OK.
✔️ Algorithm for checking the heating element's resistance:
👉 Calculate the resistance (R) using the formula: U(voltage) * U(voltage) / P (kettle power in watts).
👉 For example, if the kettle is 2000W, then 230 * 230/2000 = 26.45 Ohms.
👉 Set the multimeter to the Ohms measurement mode at 200 Ohms, touch the probes to the contact pins, and compare the value with the calculated value. If the order of the numbers is close, the heating element's resistance is OK. If the multimeter display shows "0," there's a short circuit in the heating element's coil; if it shows "1," there's a break in the heating element's filament. In both cases, replace it!
✔️ Algorithm for checking for a breakdown to the housing:
👉 Set the multimeter to continuity mode and touch one probe to any contact terminal of the heating element, and the other to the housing in different places. There shouldn't be any "circuit sound." You can also set the multimeter to 20 megaohm mode and, in the same way, touch one probe to any contact terminal of the heating element, and the other to the housing in different places. There shouldn't be any resistance numbers on the display.
