| Code | Meaning | What To Do | |------|---------|-------------| | | No water flow or sensor failure | Check if faucet is open. Clean inlet filter screen. | | E2 | Overheating (water too hot) | Reduce set temperature. Check for blocked hot water outlet. | | E3 | Temperature sensor failure | Turn off power for 10 minutes to reset. If persists, replace sensor. | | E4 | Dry heating (no water) | Turn off power immediately. Restore water flow, then restart. | | E5 | Voltage too high/low | Test supply voltage. Must match unit rating (±10%). | It requires a 30-amp service : If the
