Why S&A CWFL-6000 shows ultra-high temperature alarm (E05 or E07)?
- M
  michellejacksonAug 20, 2025
  The ultra-high temperature alarm on your S&A Chiller (displaying E05 or E07) can be triggered by several factors: * A blocked dust gauze preventing proper thermolysis. Clean the dust gauze regularly. * Poor ventilation around the air outlet and inlet. Ensure sufficient ventilation. * Unstable or extremely low voltage. Improve the power supply circuit or use a voltage regulator. * Incorrect thermostat parameter settings. Reset the controlling parameters or restore factory settings. * Frequent power switching. Allow sufficient time for refrigeration (more than 5 minutes). * Excessive heat load. Reduce the heat load or consider a model with larger cooling capacity.

What to do if S&A CWFL-6000 shows flow alarm (E01 or E02) but water pipe is connected?
- P
  Perry KellyAug 22, 2025
  If your S&A Chiller displays a flow alarm (E01 or E02) even when a water pipe is directly connected to the water outlet and inlet, 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 pipe for any leaks.

What to do if S&A CWFL-6000 displays alarm for ultra-high room temperature (E03)?
- B
  Brittany CarpenterAug 25, 2025
  If your S&A Chiller shows an alarm for ultra-high room temperature (E03), it means the ambient temperature is too high for the chiller to operate correctly. Improve ventilation to ensure the machine runs below 40 degrees Celsius.

What causes serious condensate water problem in S&A Chiller?
- R
  rhondamasonAug 26, 2025
  A serious condensate water problem in your S&A Chiller is typically caused by the water temperature being significantly lower than the ambient temperature, combined with high humidity. To address this, increase the water temperature or insulate the pipeline to preserve heat.

What to do if water drains slowly from S&A CWFL-6000 when changing water?
- L
  Larry HoodAug 28, 2025
  If water drains slowly from the outfall of your S&A Chiller during water changes, the injection port might not be open. Ensure that the injection port is open.

How to fix ultra-high temperature alarm (E05 or E07) on S&A Chiller if the dust gauze is blocked?
- S
  Stephanie FieldsAug 30, 2025
  If the S&A Chiller displays error code E05 or E07 indicating an ultra-high temperature alarm, and the dust gauze is blocked, remove and regularly wash the dust gauze to ensure proper thermolysis.

What to do if S&A Chiller shows ultra-high temperature alarm (E05 or E07) because of poor ventilation?
- H
  Heather HartSep 1, 2025
  If the S&A Chiller displays error code E05 or E07 indicating an ultra-high temperature alarm, and the air outlet and inlet have poor ventilation, ensure smooth ventilation for both the air outlet and inlet.

Why does my S&A Chiller show ultra-high temperature alarm (E05 or E07) when the voltage is unstable?
- J
  Judith YoungSep 2, 2025
  If the S&A Chiller displays error code E05 or E07 indicating an ultra-high temperature alarm, and the voltage is extremely low or unstable, improve the power supply circuit or use a voltage regulator.

What to do if S&A Chiller flow alarm (E01 or E02) occurs even with direct water pipe connection?
- R
  robert01Sep 5, 2025
  If your S&A Chiller shows a flow alarm (E01 or E02) even when using a water pipe directly connected to the water outlet and inlet, it might be due to a low water level in the storage tank. Check the water level gauge and add water until it reaches the green area. Also, inspect the water circulation pipe for any leaks.

Why does my S&A Chiller show ultra-high temperature alarm (E05 or E07) when the power is switched frequently?
- A
  Amanda MercerSep 7, 2025
  If the S&A Chiller displays error code E05 or E07 indicating an ultra-high temperature alarm, and the power is switched frequently, ensure sufficient time for refrigeration (more than 5 minutes).
