| Error codes | Overheating, flow issues, shorts |
Typical Causes of Heater Element Problems
Scale and Calcium Buildup
Mineral deposits, especially calcium, can accumulate on the heater element over time. Hard water or improper water chemistry accelerates this process. Scale acts as an insulator, reducing heat transfer and forcing the heater to work harder. You may notice reduced heating efficiency or uneven water temperatures. Regular cleaning and water balancing help prevent scale buildup and extend the life of your heater.
Corrosion and Wear
Corrosion attacks the metal sheath of the heater element, often due to unbalanced water chemistry or the presence of metal-dissolving bacteria. Over time, corrosion creates pinholes or cracks, allowing water to reach electrical components. This process weakens the heater and increases the risk of electrical shorts. You should inspect the heater regularly for signs of rust or pitting.
Electrical Shorts and Overheating
Electrical shorts occur when water contacts the internal wiring of the heater element. Cracks from mineral buildup or age allow this intrusion. Dry firing, which happens when you run the heater with little or no water, can melt the coil or sheath and lead to shorts. Improper installation, such as twisting terminals, may fracture seals and let water in. Overheating also damages the heater, causing it to fail prematurely. Routine maintenance, including balancing water chemistry and checking sanitizer levels, helps prevent these issues.
🛠️ ヒント Schedule regular inspections and maintenance to catch early signs of heater element problems before they lead to costly repairs.

Any of these issues can compromise the performance of your heater element and may require replacement.
🔍 ヒント Use a flashlight to inspect hard-to-see areas around the heater element. Even small cracks or corrosion can lead to failure.
Testing the Heater Element with a Multimeter
Setting Up the Multimeter
After your visual inspection, you need to test the heater element electrically. First, confirm that all electrical power to the spa is off. Disconnect both power leads from the heater terminals. Set your multimeter to the lowest resistance (ohms) setting. This prepares the device to measure the resistance across the heater element accurately.
Measuring Resistance (Ohms)
Place one probe of the multimeter on each terminal of the heater element. A properly functioning heater element typically shows a resistance reading between 9 and 12 ohms for most 4.0 to 5.5 kW models. Some elements may read up to 14 ohms, but values outside this range signal trouble. If your multimeter displays a very low reading (close to zero), the element has a short circuit. An infinite or very high reading means the element is open or has lost conductivity.
| Resistance Reading | Condition of Heater Element |
|---|---|
| 9–12 ohms | Normal, functioning element |
| 0オーム | Short circuit, replace element |
| Infinite/High | Open circuit, replace element |
⚠️ 警告だ： Always disconnect the heater element from the circuit before testing. This ensures you get an accurate reading and avoid false results from other components.
Interpreting Test Results
You must interpret your test results carefully. A reading within the normal range (9–12 ohms) indicates the heater element is likely in good condition. Zero or infinite resistance means the element is faulty and needs replacement. If you measure normal resistance but the spa still does not heat, check the high limit switch and thermostat. Test the high limit switch for continuity between its terminals. If you find no continuity, press the reset button and retest. For the thermostat, turn the dial fully clockwise and check for continuity. Continuity here means the thermostat works. No continuity when fully counter-clockwise is normal, as this opens the circuit.
- Normal resistance: Heater element is good.
- Zero or infinite resistance: Replace the heater element.
- Normal resistance but no heat: Test high limit switch and thermostat.
Checking for Shorts to Ground
To ensure the heater element is not shorted to ground, set your multimeter to the highest resistance range. Place one probe on a heater terminal and the other on the metal sheath of the element. An infinite reading means there is no short to ground, which is what you want. Any measurable resistance here indicates a short, and you must replace the heater element immediately. Shorts to ground can trip breakers and pose safety hazards.
🛡️ 注： Shorts to ground often result from corrosion or cracks in the heater element sheath. Regular inspection helps prevent unexpected failures.
