To improve system performance, ensure long service life, and reduce maintenance costs, we must prioritize proper operation and maintenance methods. Knowed more common problems can really help to maintanecance of cold plunge chiller used.

Some Common Problems

Despite proper operation and routine maintenance, chillers are still susceptible to damage due to age or accessories. By understanding common initial troubleshooting techniques, it can help user to know how to check and know what the problem it is.Even can help user do best maintenance for the cold plunge chiller.

Why Cold Plunge Chiller Won’t Run?

Here are some common reasons

Electrical Problems:

Tripped circuit breaker
Current overload

Incorrect voltageAny of these issues may prevent the chiller from starting.

Control System Problems:

Damaged control panel or thermostat

Abnormal temperature reading from the probeThese problems can prevent the chiller from starting.

Refrigerant System Problems:

Low refrigerant level

Refrigerant leaksEither issue may cause the chiller to fail to start.

Compressor problems:

Motor failure
Stuck compressor
Loose compressor circuit wires

Excessively high compressor currentAny of these issues may prevent the chiller from starting.

Mechanical Problems:

Broken or loose part
This can prevent the chiller from starting.

Environmental Problems:
Extreme temperatures (too hot or too cold)
This may prevent the chiller from starting.
To prevent further damage and ensure proper operation, it is important to identify the root cause of the problem if the chiller won’t start. In some cases, it may be necessary to call a professional for repair.

pumping system:
Inadequate pumping can cause a chiller to not function properly. Here are some possible causes of insufficient pumping and how to fix them:

Low Water Flow:
Inadequate pumping can cause a chiller to not function properly. Here are some possible causes of insufficient pumping and how to fix them:

Pump Failure:
If the pump fails, the chiller will not function properly. The pump needs to be repaired or replaced to fix this problem.

Solutions for Inadequate Cooling in Cold Plunge Chillers

There are several possible reasons why your chiller may not be cooling effectively. Here are some potential causes and solutions:

Low Refrigerant Level:

If the refrigerant level is too low, the chiller will not cool effectively. Check the refrigerant level and inspect for any leaks in the circulation system. Refill the refrigerant or fix any leaks to resolve this issue.

Compressor Failure:

If the compressor fails, the chiller will not cool effectively because it cannot circulate the refrigerant. The compressor needs to be repaired or replaced to fix this problem.

Clogged Pipes:

A dirty or clogged condenser coil makes it harder for the chiller to dissipate heat effectively, resulting in inadequate cooling. Clean or replace the condenser coil to resolve this issue.

Incorrect Thermostat Setting:

If the thermostat is not set to the proper temperature, the chiller may not maintain the desired temperature. Adjust the thermostat setting as needed to fix this problem.

Airflow Problems:

If there is an airflow issue, such as a clogged air filter or damaged ducting, the chiller may not be able to circulate cool air adequately. Clean or replace the air filter and address any damaged ducting to fix this problem.

A number of factors can cause inadequate cooling, so it is essential to identify and resolve the source of the problem as soon as possible to prevent further damage and ensure the unit is working properly. If you are unable to fix the issue, it may be necessary to contact a professional for repair.

Solutions for Compressor Failures in Cold Plunge Chillers

First, check whether the compressor power connection line is loose, as rough transportation may impact the connection even if it was securely fixed by the manufacturer. Secondly, verify whether the power indicator light is on to ensure the compressor is receiving power. Finally, check whether the current of the chiller compressor exceeds the preset range; if the current is outside the specified setting, the chiller and the fan won’t operate.

What the impact of Environmental conditions

The chiller may be overloaded due to changes in ambient temperature. Similarly, changes in the location of the chiller (near other heat-generating equipment or in a closed and unventilated environment, etc.); or even changes in line voltage may impair the chiller’s ability to dissipate heat.

Understanding Common Cold Plunge Chiller Faults

When performance is impaired, the chiller will stop running to protect the chiller and display a fault or error code. These codes represent the corresponding problem diagnosis or problem display. (You can refer to the parameters provided by the supplier for comparison)

Here are some of the most happened typical alarms and faults:

Low temperature warning:

The water temperature has dropped below the temperature value set by the user. This may be caused by insufficient heat load or a low temperature alarm setting that is too high.

High temperature warning:

The water temperature has exceeded the temperature limit set by the user. This may be caused by high heat load or a low high temperature alarm setting.

Over temperature safety alarm:

The water temperature has exceeded the safety cutoff value specified by the chiller or user. Refrigeration system problems or low temperature safety settings may be the cause of this.

Low liquid level warning:

The reservoir no longer contains a sufficient amount of coolant. Leaks or evaporation in the circulation system may be the cause of this.

Water temperature probe failure		Check if the probe wire is damaged or disconnected Check if the probe wire end is loose
Water flow fault		Caused by blocked water flow, it is necessary to check: Check if the water inlet of the tub is blocked (hair, paper towels, towels, leaves, etc.) Check if the water outlet of the tub is blocked by foreign objects (hair, paper towels, towels, leaves, etc.) If there is a mesh at the water inlet, the mesh needs to be cleaned. The filter cartridge needs to be cleaned or updated.
Low voltage fault		The compressor pressure is too ow, resulting in no short circuit between the low pressure detection port of the main board and the public
High voltage fault		The compressor pressure is too high, resulting in no short circuit between the high-pressure detection port of the main board and the public
Current overload		Ensure smooth air intake from the back of the chiller (need to be at least 0.5M away from solid walls or solid obstacles) The chiller can not work under the condition of ambient temperature higher 45°C In the main interface, click to enter the settings menu and reset F11 to greater than the alarm value.
water pump stuck fault		It is usually caused by impurities (sand/hair/paper towels/leaves/insects, etc.) entering the water pump. Disassemble the water pump, remove the foreign objects, and then reassemble the water pump. If water pump was damaged, please install a new pump directly. Check there is must be a filter element inside of filter system.
no water flow fault		Check if the water level has submerged the water inlet and outlet of the tub. If not, continue to add water to submerge the water inlet and outlet. If the water level submerges the water inlet and outlet of the tub, push water pipe to pour water from the water inlet into the chiller until no large bubbles appear at the water outlet, and then start the chiller.
High temperature fault		Poor contact of communication interface and communication line to connector,or burning of communication chip
Low temperature fault		The equipment has reached the set service life, please contact the engineer
Communication fault		1. Check if the probe wire is damaged or disconnected 2. Check if the probe wire end is loose
