Floor Protect Pan - GE CDT865SxJ0 Series Technical Service Manual

Rinse Aid Sensor
This sensor works the same as a turbidity sensor,
~ 1 VDC is sent to an LED inside the rinse tank, the
"photo sensor" sends a signal back to the control.
• .5 - 2 VDC signal indicates a level below 20 ml.
Three consecutive "low" readings are needed to
trigger a low reading.
• 3 to 5 VDC signal indicates a 20 ml to full level.
• Sensing is activated by the door closing.
• Sensing cycle is ~ 50 seconds long.
• Control will indicate full after one full reading.
•
Steam button (depending on model) seven times
within 5 seconds. Repeat this process to turn the
Low Rinse Aid indicator back on.
Diagnosing Rinse Aid Sensor
Open the door for one minute, then close the door
to initiate the rinse sensor sensing mode.
LED Operation: Check for ~1 VDC green/black –
tan/white (pin 1 - pin 3).
Sensor Operation: .5 - 5 VDC from blue/red – tan/
white (pin 2 - pin 3).
~ .5 – 2 VDC would indicate a low or empty reading.
~ 3 - 5 VDC would indicate full or mostly full reading.
Notes:
Voltages may be checked for 50 seconds
immediately after the door is closed. False readings
may occur if door is not opened to 90° and not left
in this position for 1 minute.

Floor Protect Pan

of the 2016 Stainless Steel Tub Dishwashers. This
feature will hold 24 ounces of water on a level
pan is held in place with 4 tabs.
Some models have a moisture sensor that will alert
the consumer of a leak under the dishwasher and
advise that they call for service.
If water is detected when the dishwasher is running
a cycle, the dishwasher enters a drain mode for up
to 70 seconds and cancels the cycle. The LCD screen
Manual or Use & Care book advises the consumer to
call for service. If water is detected in an idle state
(no cycle running), then the dishwasher will indicate
Leak Detected and will not start.
A 5 VDC signal is sent to the moisture sensor. If
enough water leaks into the pan it will short across
the sensor probes, returning 5 VDC back to the
control. This will alert the consumer of a leak.
The fault may reset if no water is detected. It
is possible for the water to evaporate and the
dishwasher would restart with no water detected.
Only active faults are displayed on the control.
If the consumer tries to restart the dishwasher with
water still detected, the dishwasher will not restart.
A physical inspection should be completed to
determine the source of the leak, with repairs
performed as needed. The moisture sensor may
have to be cleaned and dried, by wiping it with a
soft cloth.
