CME1356R and CME1656R
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 AutoIQ 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: 5 evaporator models have a different float stem from the 6 evaporator machines. Do not mix the two.
5 evaporator (CME1356) uses a tan stem
6 evaporator (CME1656) uses a brown stem 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.
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 left 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.
8.Reverse to reassemble.
Note: Do not push sensor tip in too far. There should be about an 1/8" gap between the tip and the inner wall of the water discharge hose.
