TROUBLESHOOTING
ALARM CODE
POSSIBLE CAUSE
SOLUTION
E0
Cold room temperature sensor not working properly
•
Check that cold room temperature sensor is
working properly
•
If the problem persists replace the sensor

(e.g. thermal protection or max pressure
switch)
(All outputs except the alarm one – where applicable – are deactivated)
•
Check that compressor is working properly
•
Check compressor absorption
•
If the problem persists contact the technical
assistance service
Ed
