Solution
Ensure the valve has a proper air supply and seals
properly. If not, service the valve as necessary.
Visually inspect the machine and hoses for sign of
leakage. NOTE: This error will display after 2 full
piston strokes so the leak will be substantial.
Fill tanks
Fill tanks with material
If the tanks appear to have plenty of material check to
make sure the level sensor is connected to the proper
port and that the cord is not damaged
Replace level sensor
If the tanks appear to have plenty of material check to
make sure the level sensor is connected to the proper
port and that the cord is not damaged
Make sure the feed pumps are operating properly
Check for loose or disconnected wires or plugs
Replace level sensor
Check hose connecions between tank output, and
pump inlet. Check tank fittings.
Replace level sensor
Check oil level and if low add more hydraulic fluid
Check to ensure the hydraulic oil level sensor is
properly connected to the MCM and that the wire has
not been damaged
Replace sensor
Inspect hydraulic driver end seals and early leak
detection tubing. Replace seals as necessary and
replace lost oil.
Inspect the hydraulic reservoir fittings and filter for
leaks. Repair or replace as necessary and replace
lost oil.
Add oil.
If error persists and performance can no longer
satisfy the user requirements the motor will need to
be replaced

Check that flow meter is matched to nominal pump
output
Check for loose or disconnected wires or plugs
