Removal and Replacement: Water Level Sensor
1. Remove front panel.
2. Push and hold the OFF button. Release it when
the machine stops.
3. Trace wire harness from water level sensor to
the Controller (#2). Unplug the harness from the
controller.
4. Lift the pump and mounting plate up enough to
remove the float from the stem.
5. Remove two screws holding the sensor to the
pump bracket and lift the sensor up and out of the
machine.
6. Reverse to reassemble.
Note: Single evaporator models have a different
float stem from the double evaporator machines.
Do not mix the two. The color of the float stem is
supposed to match the color of the reservoir
overflow standpipe (the standpipe is also different
between single and double evaporator machines).
Discharge Line Temperature Sensor
1. Remove front panel, push and release the Off
button.
2. Remove top and left side panels.
3. Locate discharge line sensor. It is attached to
the discharge line of the compressor, 6" from the
compressor discharge port.
4. Un-snap the clip holding the sensor to the
discharge line.
5. Trace the sensor wires back to the controller,
they are plugged into #5 with the water
temperature sensor, and must be replaced with it.
6. Reverse to replace, be sure that the discharge
line sensor is 6" up from the compressor discharge
port. The discharge line sensor is marked with
yellow tape.
Note: Route wires so they do NOT contact the
discharge line.
Water Temperature Sensor
Note: This sensor is replaced as a set with the
Discharge Temperature Sensor.
1. Remove front panel.
2. Push and release Off button.
3. Remove 1 plastic bolt and the reservoir cover.
4. Locate water temperature sensor (inserted into
pump discharge hose).
5. Pull out to remove.
6. Trace back to AutoIQ Controller, unplug from
#5.
7. Remove the Discharge Line temperature
sensor.
