What It Means
Breaker Trips When Heat Is Called
Likely Causes
- Heater element leakage to ground
- Heater relay/board fault
- Wet heater terminals
- Flow issue causing unsafe heat state
- Incorrect voltage or bonding issue
Next Checks
- Stop using heat until verified
- Confirm whether pumps run without heat if the manual permits that observation
- Capture exact trip timing, heater tube label, display code, and water condition
- Heater isolation and resistance/leakage testing require qualified service
- Do not bypass the heater, GFCI, or safety controls
