Problem Possible Cause Solution
Display for Hose (or
Head) = EO1
Display for Hose (or
Head) = EO2
1.No Hose (or Head) is
connected.
2.Disconnection between
ASU and Hose (or be-
tween Head and Hose).
3.Disconnection at X4 on
PCB.
4.Hose(orHead)sensoris
inoperative.
1.Hose (or Head) sensor
short circuit.
2.Shortcircuitinplugcon-
nection between ASU
and Hose (or between
Hose and Head).
3.Inoperative PCB.
1.Connect Hose (or Head) if need-
ed. If not needed, ignore display.
2.Check plug connection.
3.Make proper connection.
4.Check resistance and compare to
resistance table.
a. For head: if sensor is
inoperative, replace sensor.
b. For hose: if sensor is
inoperative, replace hose.
