FAQ

What should I do if the ice full indicator is on but the proximity switch doesn’t react?
Check if the evaporator connector is assembled well and if the proximity switch is sensitive. You might need to re-install the connector or replace the switch.
How can I troubleshoot when there’s no water in the ice machine tank?
Ensure that the water tank is plugged correctly and check the water supply. If the pump is clogged, it may need cleaning or replacement.
What steps should be taken if the ice machine is making thin ice?
Adjust the making time through “-” to reduce it, and check if the spray pipe needs adjusting.
What can be done if the compressor is not cooling despite working?
This could indicate a compressor leak. It’s necessary to check for leaks and possibly replace the compressor.
If the fan in the ice machine is not working, what could be the issue?
The problem could be due to a non-sensitive condenser probe, a jammed fan, or a broken fan. Depending on the cause, you may need to unplug or replace the probe and adjust or replace the fan.
