| Error Code | Error Name | Symptoms | Possible Causes | Solution | Image |
|---|---|---|---|---|---|
| E0 | Water Leakage Protection | All loads shut down, water dispensing disabled (E0 has the highest priority) | Loose internal piping in chilling unit causing leakage | Remove side panel to check and re-secure any loose pipes | / |
| Water accumulation in leakage protector | Remove left side panel to clean accumulated water in leakage protector | ![]() | |||
| Water tank leakage | Contact after-sales service | / | |||
| E1 | Temperature Sensor Fault | Chilling disabled; dispensing and other functions normal | Damaged or faulty temperature sensor | Contact after-sales service | / |
| E3 | Cooling Fault | Water temperature unchanged after 20 minutes or large deviation from set temperature | Foreign object blocking both air inlets of the unit | Remove any foreign objects blocking both air inlets | ![]() |
| Cooling fan failure or abnormal(stopping after cooling is normal) | Contact after-sales service | ||||
| Not enough space for hot air to escape | Place the unit in a well-ventilated area with good airflow | ||||
| / | No Error Code, Cooling Fault | Water temperature unchanged after 20 minutes or large deviation from set temperature | Not enough space for hot air to escape | Place the unit in a well-ventilated area with good airflow | / |
| E4 | Bubble Tank Refill Error | Bubble tank not refilled within 15 minutes | No water supply to bubble tank | Check if water supply is normal | / |
| Excessive CO₂ pressure | Maintain CO₂ pressure below 0.5MPa | ||||
