1. Water pump failure
2. Water piping blocked
3. Water flow switch seized
1.Discharge redundant refrigerant
from HP gas system
2.Clean the air exchanger
1.Check if there is any gas leakage ,
re-fill the refrigerant
2.Clean the air exchanger
3.Replace the filter or capillary
Check if the water flow is enough and
flow in right direction, or else the
flow switch could be failed.
