How to Fix / Troubleshooting
Safety: Turn off power and be cautious of hot water in the storage tank.
- 1. Locate DHW sensor: On Energy Kinetics System 2000 with a storage tank, find the domestic hot water sensor inserted into the tank well.
- 2. Check insertion and clamp: Ensure the sensor is fully inserted into the well and secured with its clamp or retainer.
- 3. Inspect wiring: Trace the sensor wires back to the Energy Manager. Tighten any loose connections and repair damaged cable.
If the error persists, the DHW sensor likely needs replacement. A technician can verify resistance values and confirm.
