Why does my S&A CW-7800 display ultra-high temperature alarm (E05 or E07)?
- W
  William PatelAug 8, 2025
  If your S&A Chiller displays error code E05 or E07, indicating an ultra-high temperature alarm, several factors could be responsible: * The dust gauze may be blocked, hindering thermolysis. Regularly unpick and wash the dust gauze. * The air outlet and inlet may have poor ventilation. Ensure smooth ventilation for both. * The voltage may be extremely low or unstable. Improve the power supply circuit or use a voltage regulator. * The thermostat parameter settings may be incorrect. Reset the controlling parameters or restore factory settings. * The power may be switched frequently. Allow sufficient time for refrigeration (more than 5 minutes). * There may be an excessive heat load. Reduce the heat load or use a model with a larger cooling capacity.

What to do if S&A CW-7800 Chiller alarms for ultra-high room temperature (E03)?
- D
  Dustin PrestonAug 12, 2025
  If your S&A Chiller displays error code E03, indicating an alarm for ultra-high room temperature, it is likely because the working ambient temperature is too high for the chiller. To resolve this, improve ventilation to ensure the machine operates below 40 degrees Celsius.

How to troubleshoot an S&A CW-7800 Chiller that turns on but is unelectrified?
- J
  jensenjaimeAug 16, 2025
  If your S&A Chiller is on but not working, it could be due to the following reasons: * The power cord may not be properly connected. Check and ensure the power interface and plug are securely in place and making good contact. * The fuse might be burnt out. Open the electric box cover, inspect the protective tube, and replace it with a spare if needed. Also, verify that the power supply voltage is stable and that the power interface and plug are properly connected.

What to do if S&A CW-7800 flow alarm (E01 or E02) persists despite direct water connection?
- D
  Diane PerezAug 21, 2025
  If you're experiencing a flow alarm (E01 or E02) on your S&A Chiller, and you've connected a water pipe directly to the outlet and inlet but still have no water flow, the water level in the storage tank may 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.

Why does S&A Chiller flow alarm occur with equipment but not with direct water pipe?
- S
  stephensonjamesAug 26, 2025
  If you're experiencing a flow alarm (E01 or E02) on your S&A Chiller while it's running with other equipment, but there's no alarm when using a direct water pipe connection, the water circulation pipes may be blocked or deformed due to bending. Inspect the water circulation pipes to resolve this issue.

Why is there serious condensate water problem with my S&A Chiller?
- J
  Justin SavageAug 29, 2025
  If you observe significant condensation with your S&A Chiller, it could be because the water temperature is much lower than the ambient temperature, coupled with high humidity. Consider increasing the water temperature or insulating the pipeline to preserve heat.

Why does water drain slowly from S&A Chiller during water changing?
- A
  Alexis LunaSep 3, 2025
  If water drains slowly from the outfall of your S&A Chiller during water changes, ensure that the injection port is open.
