Diagnosis
1. Open the valve
2. Change a new flow switch
3.Clean or change a new filter
1. Reinject water or change to a
new pump of larger water flow;
2. Change a new high-pressure
switch
3. change a new filter
4.Change a new EEV
1.Amend the leakage and
reinject the gas
2.change a new filter
1. Put away the blow area
2. Clean the evaporator
3. Change a new sensor
1.Amend the leakage and
reinject the gas
2.Change a new sensor
