    How to fix S&A CWFL-500 ultrahigh water temperature alarm (E2)?
    • M
      Matthew PetersonAug 18, 2025
      If your S&A Chiller displays an E2 error, indicating an ultrahigh water temperature alarm, several factors could be responsible. First, the dust gauze might be blocked, hindering thermolysis, so disassemble and clean it regularly. Ensure proper ventilation around the air outlet and inlet. Unstable or extremely low voltage can also trigger this alarm, so improve the power supply circuit or use a voltage regulator. Resetting the thermostat parameters or restoring factory settings might help if the settings are improper. Allow sufficient time (more than 5 minutes) for refrigeration between power cycles. Finally, excessive heat load can cause this issue; reduce the heat load or consider a model with larger cooling capacity.

    How to fix S&A CWFL-500 ultrahigh room temperature alarm (E1)?
    • J
      johnstonangelaAug 20, 2025
      If your S&A Chiller displays an E1 error, it indicates an ultrahigh room temperature alarm. This typically means the room temperature is too high for the chiller to operate effectively. Improve the ventilation to ensure the machine operates below 40° room temperature.

    Why S&A CWFL-500 has condensate water?
    • K
      Katherine HillAug 23, 2025
      Condensation on your S&A Chiller can occur when the water temperature is significantly lower than the ambient temperature and humidity is high. To address this, increase the water temperature or insulate the pipeline to preserve heat.

    Why does S&A CWFL-500 Chiller water drain slowly?
    • C
      carlosriosAug 26, 2025
      If water drains slowly from the drain port of your S&A Chiller when changing the water, check that the water supply inlet is open.

    How to resolve S&A CWFL-500 startup flow alarm?
    • J
      John CruzAug 28, 2025
      If your S&A Chiller shows a flow alarm at startup, it may be due to bubbles in the water pipe. Exhaust the air from the system.

    Why is my S&A CWFL-500 showing an ultra-high temperature alarm (E2)?
    • Q
      qjohnsonAug 30, 2025
      An ultra-high temperature alarm (E2 on the temperature controller) on your S&A Chiller can be triggered by several factors. Check for a blocked dust gauze and clean it regularly to improve thermolysis. Ensure proper ventilation around the air outlet and inlet. Voltage fluctuations can also cause this, so improve the power supply or use a voltage regulator. Reset the thermostat parameters or restore factory settings in case of improper settings. Allow sufficient refrigeration time (over 5 minutes) between power cycles. Finally, reduce the heat load or consider a chiller model with larger cooling capacity if there's excessive heat.

    How to fix S&A CWFL-500 that turns on but is unelectrified?
    • N
      Natasha RossSep 2, 2025
      If your S&A Chiller turns on but seems unelectrified, first, check that the power cord is properly plugged into the power interface and that the connection is secure. Also, inspect the fuse in the electric box. If it's burnt out, replace it with a spare, and ensure the power supply voltage is stable. Again, check the power cord and interface for good contact.

    What to do if S&A CWFL-500 Chiller has flow alarm (E6) with equipment but not with direct water pipe?
    • P
      pamela25Sep 4, 2025
      If your S&A Chiller displays a flow alarm (E6) when running with other equipment, but operates normally with a direct water pipe connection, the water circulation pipes may be blocked or deformed. Inspect the water circulation pipes.

    What causes an ultra-high room temperature alarm (E1) on an S&A Chiller?
    • J
      Joshua SmithSep 7, 2025
      If your S&A Chiller displays an alarm for ultra-high room temperature (E1), it means the working ambient temperature is too high. Improve ventilation to ensure the chiller operates below 40 degrees Celsius.

    Why S&A CWFL-500 displays E6 error even with direct water pipe?
    • M
      morrisontamaraSep 9, 2025
      If your S&A Chiller shows a flow alarm (E6) even with a direct water pipe connection, the water level in the storage tank might be too low. Check the water level gauge and add water until it reaches the green area. Also, inspect the water circulation pipes for any leaks.
