Why doesn't my chiller work after placing different place to use?

Why doesn't my chiller work after placing different place to use?

1.Make sure the water pump and chiller are plugged in.
2.After the machine is started, the machine will start for a few minutes and will not cool down immediately.
If the set temperature is similar to the water temperature, the water will not cool down (please set the temperature range larger). For example, mine is set to 61, which has a 4-degree delta, so it will continue to work at 65 degrees until it reaches 61 degrees and cycle from there. Please adjust it and give it a try.
