Ice Bath Water Chiller Low Temperature Fault: Top Solutions from Chiller Manufacturer

Why Is Your Ice Bath Water Chiller Experiencing a Low Temperature Fault?

The COLDCHILLER manufacturer equips its ice bath water chillers with a fault or error code display function to quickly identify issues affecting the performance of the chiller unit and provide solutions. Due to the specificity of error codes, operators can promptly determine the cause of the problem and assist users in resolving it.

The “EL” error code indicates that the ice bath chiller has encountered a low-temperature fault. The possible reasons for temperature faults in the water chiller include the following:

The Water Temperature Probe Measures a Temperature That Exceeds the “F10” Setting Value

F10 is a parameter in our ice bath water chiller, and its main content is the lower temperature limit. If the water temperature probe detects that the water temperature is lower than the user-set temperature and exceeds the F10 setting value, the machine will issue a low temperature warning.

Sensor Failure

Loose sensor plug, poor solution, or water ingress during the refrigeration process can cause the sensor to fail, misdetect low temperatures, and generate a low temperature warning.

Solution for Ice Bath Water Chiller Low Temperature Fault: Easy Steps

COLDCHILLER provides you with the most professional knowledge and solutions for ice bath chillers.

Check if the Water Temperature Is Lower Than the Set Value in F10

If the actual water temperature is lower than the set value in F10, the minimum temperature limit needs to be lowered. Adjust F10 to a value lower than the alarm value, or adjust F10 to 2 (the lowest allowable value).

Set F13 F20

F13 display tempurature switch indicates the switch of two temperature probes. “0” indicates is the water inlet temperature probe, and “1” indicates the titanium bulb(water outlet temperature probe).

When a low temperature warning appears, you can find the “Setting” button in the control panel. Click it and you can see three options: Parameter, Monitor and Light. Press the “Parameter”, enter the initial password “8888”, and press “√” to enter the next step. You can see that there are many parameters. Find the F13 code in it. Click the value in the “value” column.

Then a new window will pop up on the screen. If your current value is displayed as “0”, you need to enter the value “1”, if it is displayed as “1”, you need to enter the value “0”. After entering the value opposite to your current screen, you need to click “√”, and then click “return” to complete the setting.

Confirm that you are currently on the parameter page, and slide down to find F20. F20 is the function of detecting the temperature difference of water inlet and outlet in our cold plunge chillers. The value “0” indicates that the function is being activated, and the value “1” indicates that the function is turned off.

Click the “value” column and enter the value “0” in the pop-up window to turn off the function of the ice bath water chiller to detect temperature difference and ignore the temperature difference.

Click “√” to complete the setting. Click “return” in the setting panel to exit the setting.

Click “confirmed setting” in the upper right corner of the parameter page to complete the overall setting. Finally, click the “return” button in the upper right corner of the screen again to return.

Practical Solution for Ice Bath Chiller EL: Replace Temperature Probe

If the above solutions still fail to solve the low temperature warning problem, COLDCHILLER manufacturer recommends that you replace temperature probe. Don’t worry about needing to purchase a separate temperature probe, we will send you a new temperature probe for replacement.
Next, we will explain how to replace the temperature probe, we will take the titanium bulb(water outlet temperature probe) as an example. You can also replace it according to our video below.

• Tools you need: electric drill, wrench, scissors, rubber ring, thread glue, new temperature probe, cable tie
• Safety measures: Disconnect the power supply of the ice bath water chiller and unplug it.
• How to know which temperature probe is faulty: Find the setting button in the control panel, click it. Press “Monitor”, enter the password and you can see “Evaporator internal temperature” and “Water inlet temperature”.
  If “Evaporator internal temperature” is negative tens of degrees, it can usually be seen that the titanium bulb is faulty. If “Water inlet temperature” is negative tens of degrees, it can usually be seen that the water inlet temperature probe is faulty.
  Usually, the fault is usually the titanium bulb.

Disassembling the Chiller Casing

1. Use an electric drill to remove the screws on the chiller frame. And then take apart the wire connected with frame.

2. Use an electric drill to remove the screws on the top cover of the chiller. And then remove the top cover of the chiller. Take off the plastic wire groove cover.

Remove the Old Temperature Probe

3. Find the old temperature probe you want to replace (the plug is usually located on the top of the chiller), unplug it.

4. Use scissors to cut off the cable ties.

5. Find the other end of the temperature probe according to the wiring and unscrew it.

6. Remove the old temperature probe. Avoid touching other lines during this process.

Installing a New Temperature Probe

7. Find the water outlet and use a rag to wipe it dry.

8. Add a rubber ring to the threaded section of the new temperature probe and apply spiral glue. It is worth noting that it needs to be applied evenly, but not too full.

9. Screw the threaded section of the temperature probe onto the water outlet.

10. Let it stand for 4 hours and wait for the glue to dry. (If using other glue, please let it stand for a period of time according to the manufacturer’s recommendations)
11. Insert the plug into the temperature probe position.

Reinstall the Chiller and Connect the Power Supply

12. Install the plastic wire groove cover.
13. Tie the cable ties and cut off any excess.

14. Install the top cover of the chiller.
15. Assemble the frame back and screw back all the nails and handles.

16. Reconnect the power supply and check whether the chiller is operating normally.

Chiller Manufacturers’ Advice: How to Maintain a Commercial Cold Plunge Chiller?

Maintenance of chillers is very important. Proper maintenance of water chillers can reduce the possibility of water chiller failure and ensure the normal operation of ice bath water chillers.

Daily Maintenance

• Clean dust and stains on the surface of the water chiller for ice bath to prevent dust accumulation and affect the heat dissipation function of the chiller.
• Check the operating status of the water chiller ice bath to see whether it can refrigerate, whether there is abnormal vibration, and whether the noise is too loud.
• Check whether the chiller shell is damaged, whether the pipes are loose and damaged, whether the plugs are loose, and whether the control panel can operate normally.

Regular Maintenance

• Clean or replace the water chiller filter cartridge. We recommend that you replace the water after using it 10-15 times. You can clean the filter when changing the water. If you are using a paper filter cartridge, we recommend that you replace it every two weeks.
  If you are using a stainless steel filter cartridge, we recommend that you replace it every six months or 1 year. The specific replacement time depends on the number of times you use it.
• Regularly check the use of the internal circuits of the chiller to see if the circuits are loose or damaged, and check whether the electronic components can operate normally.
• Use a pressure gauge to check whether the refrigerant capacity is sufficient. If necessary, professionals are required to replenish the refrigerant.
