Calibrating the WE-6 Temperature Circuit

1. Open the control compartment to gain access to
the WE-6 computer board.
2. Viewing the WE-6 computer board from the rear,
locate the blue rectangular plastic component
with a white plastic screw head in the center. This
is the temperature calibration potentiometer.
Turning this screw head adjusts the temperature
reading.
3. Fill the machine sump with water and place an
accurate temperature sensor in the water to
provide a measurement of the actual water
temperature. The WE-6 temperature readout is
then adjusted to match this to the nearest unit. It
is easiest to program a Wash 3 (no agitation) for
10 seconds (to prevent rotation and subsequent
damage to the temperature sensor), then a cold
fill to high level, followed by a Wash 3 for
9 minutes and 99 seconds. Do not press STOP.
Calibration must be completed before the last
wash step finishes. Remove power to machine
after calibration until computer goes off to
prevent rotation when the cycle ends.

4. Start the cycle. When the water level is reached
(and the external temperature sensor is
submerged), press the DISPLAY
TEMPERATURE key on the WE-6 keypad. The
display will show a reading in either degrees F or
degrees C, or the conversion will have to be made
by calculation as follows:
Degrees F = (Degree C x 9/5) + 32
Degrees C = (Degrees F - 32) x 5/9
5. While pressing the DISPLAY TEMPERATURE
key, use the screwdriver to turn the temperature
calibration screw until the WE-6 displays the
same temperature as the external sensor, which
should be accurate at least to the nearest degree.
Turning the screw clockwise increases the
displayed temperature.
6. When the temperatures match, calibration is
completed. Close the control compartment and
remove the external temperature sensor. To
prevent rotation, DO NOT PRESS STOP; instead
remove power to the machine until the computer
goes off.
*As an alternative, if an external sensor is not
available, measure the temperature of the inflowing
water, and follow step 5.
