Service Manual #513721 21 U421-I2A & U431-I2A Model Machines
ERROR CODE 10 - AMBIENT SENSOR
The Ambient Temperature Sensor Error (E10)
indicates a failure of the condenser air inlet
temperature sensor or if the sensor is out of
range. If the control panel displays an E10, press
the On/Off button for the cylinder to turn it off
then back on. If the control panel still displays
the error condition code, refer to the machine's
wiring diagram and the Temperature Sensor
Table. Check each lead of the sensor to ground
for continuity. If continuity is found, replace the
sensor. To check the resistance of the sensor,
place a thermocouple at the condenser air inlet.
Compare temperature and sensor resistance with
the table as reference. If measured value does not
coincide with a value on the table (± 400 ohms),
replace the sensor.
ERROR CODE 11 - PRIME
The Prime Error (E11) occurs when the pressure
switch does not shut off the pump after an
extended period of continuous running. This
usually occurs if there is a leak in the hose or if
there is a low mix condition. The error can also
indicate a bad pressure switch.
ERROR CODE 12 - LEFT HOPPER SENSOR
The Left Hopper Sensor Error (E12) will not occur
on the U421-I2A or U431-I2A.
ERROR CODE 13 - RIGHT HOPPER SENSOR
The Right Hopper Sensor Error (E13) will not
occur on the U421-I2A or U431-I2A.
ERROR CODE 16 - ROTATE HOSE
The Rotate Hose Error (E16) occurs when the
Hose Service Limit has been met.
Rotate or replace the pump hose and reset the
hose service time by pressing and holding the
Pump button until the reset message appears
on the Current Status Screen.
ERROR CODE 21 - SPIGOT OPEN TIME
The Spigot Open Time Error (E21) occurs when
the spigot is open continuously for 10 minutes.
The machine goes into Sleep 3 mode when an
E21 occurs.
If the control panel displays and E21, make sure
the spigot handle is fully closed. The switch can
be held open if the spigot body and front door
were not assembled correctly or lubricated.
Test the spigot switch and replace if necessary.
Check that the spigot assembly is operating
correctly.
