Possible Causes

Disconnected or failed recirculation pump, Incorrect pump wiring, Overloaded pump circuit, Faulty PCB pump driver

How to Fix / Troubleshooting

Safety first: Turn OFF power and close isolation valves to the recirculation loop if present.

Steps:

  • 1. Check pump power: Ensure the recirculation pump is properly connected to the heater’s pump terminals or external power source as specified by Takagi.
  • 2. Inspect pump wiring: Look for loose or damaged wires at the pump and heater.
  • 3. Verify pump operation: With power restored (and observing safety), feel or listen for pump operation when recirculation is called. If the pump is seized or noisy, it may need replacement.
  • 4. Professional service: If wiring and pump are good but error 761 persists, the heater’s control board pump circuit may be faulty and should be replaced by a technician.
