  There are several reasons why the compressor might not be starting. First, ensure the machine is turned on by pressing the start key. Second, the water temperature might have reached the set temperature, causing the machine to stop. It will restart automatically when the water temperature changes. Third, the compressor has a built-in protection mechanism that requires a 3-minute waiting period after shutdown before restarting. Finally, the machine might be in a fault or protection state, refer to the description in the table at point 3 for detailed information.
