Chilling Unit Error Codes and Troubleshooting

Error CodeError NameSymptomsPossible CausesSolutionImage
E0Water Leakage ProtectionAll loads shut down, water dispensing disabled (E0 has the highest priority)Loose internal piping in chilling unit causing leakageRemove side panel to check and re-secure any loose pipes/
Water accumulation in leakage protectorRemove left side panel to clean accumulated water in leakage protectorImage
Water tank leakageContact after-sales service/
E1Temperature Sensor FaultChilling disabled; dispensing and other functions normalDamaged or faulty temperature sensorContact after-sales service/
E3Cooling FaultWater temperature unchanged after 20 minutes or large deviation from set temperatureForeign object blocking both air inlets of the unitRemove any foreign objects blocking both air inletsImage
Cooling fan failure or abnormal(stopping after cooling is normal)Contact after-sales service
Not enough space for hot air to escapePlace the unit in a well-ventilated area with good airflow
/No Error Code, Cooling FaultWater temperature unchanged after 20 minutes or large deviation from set temperatureNot enough space for hot air to escapePlace the unit in a well-ventilated area with good airflow/
E4Bubble Tank Refill ErrorBubble tank not refilled within 15 minutesNo water supply to bubble tankCheck if water supply is normal/
Excessive CO₂ pressureMaintain CO₂ pressure below 0.5MPa
E7Chilling Tank Refill ErrorChilling tank not refilled within 20 minutesNo water supply to chilling tankCheck if water supply is normal/
/Sparkling Water Dispensing ErrorDispensing fluctuationCO₂ pressure too highSet CO₂ 0.35-0.4 MPa, dispense 30 s to relieve pressure/
CO₂ pressure too highFaulty CO₂ gauge may misread. Reduce pressure until smooth
No bubbles in sparkling waterInsufficient CO₂ in waterCO₂ ≤ 0.1 MPa. Replace cylinder
Insufficient CO₂ in waterFollow Initial Sparkling Water Commissioning instructions
