| Symptom | Possible Cause | Remedy | |---------|----------------|--------| | Pump does not run (no sound) | No power, tripped breaker, or faulty timer | Check circuit breaker, fuses, and timer settings. Measure voltage at pump leads. | | Pump does not run (hum but no flow) | Air lock or blocked impeller | Turn power off and on to purge air. If no improvement, isolate pump and clean rotor cavity. | | Intermittent or slow hot water delivery | Check valve stuck, low thermostat setting, or undersized pipe | Verify check valve operation. Raise temperature set point if safe. Assess pipe diameter. | | Pump runs continuously | Thermostat set too high, defective sensor, or timer set incorrectly | Lower temperature set point. Check timer program. Replace sensor if needed. | | Excessive noise (grinding, rattling) | Debris in rotor, worn bearings, or cavitation | Clean rotor cavity. If noise persists, replace pump. Ensure no air in system. | | Water leaks from pump housing | Damaged O‑ring, loose screws, or cracked casing | Tighten screws. Replace O‑ring. If crack is present, replace pump. | | Pump is hot to the touch | Normal operation – pump casing will be warm | No action required unless temperature exceeds 165°F (74°C). Check for adequate ventilation. | | The LED flashes a pattern | Communication error (wireless models) | Refer to the specific LED code in the manufacturer’s instructions. | The Thermotech TT91 is more than a piece
