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 (or Head) sensor is
inoperative.
1. Hose (or Head) sensor
short circuit.
2. Short circuit in plug con-
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.
