Troubleshooting Tip: If breaker trips during testing, unplug the element. If breaker remains on when unplugged but trips when reconnected, the element is faulty. Use an Ohm meter to measure terminals - should read approximately 10.5K ohms. A reading of 0K indicates an open circuit. If breaker doesn't trip and readings are normal, investigate other no-heat causes: pressure switch malfunction, clogged filter, circulation issues, or control board problems. This model includes a pressure switch which may require separate replacement if causing heating issues.

DuPont Teflon® industrial coatings deliver superior performance across multiple industries, providing exceptional chemical resistance, corrosion protection, and abrasion durability in demanding applications.
