Rotation Sensor
The rotation sensor must “read” the key on the basket
shaft or pulley. The sensor must be set approximately
1/4 inch from the key or pulley. Look for the light on
the sensor to come on as the key passes the sensor; this
is a correctly operating sensor. If no light appears,
either the sensor is out of range or the key/pulley or
the sensor is bad. In addition, if the light stays on
continuously, then the sensor is too close to the
component or the sensor is bad.
Safety Tumble/Anti-Wrinkle
At the end of the cool down cycle, the tumbler will
stop and display “END.” The DMP control will
automatically rotate the basket for 5 seconds every
2 minutes for a total of 20 minutes, until some
function of the tumbler is activated/deactivated by the
user.
Operational Check for the Board Diagnostics
1. “dor” indicates that the loading or lint door is
open.
2. Cycle the tumbler to check if the buzzer
activates.
3. “P-F” indicates that the thermistor is short
circuited or open circuited.
4. “bbt” indicates a broken belt condition or a faulty
rotation sensor. (Only available on tumblers with
the rotation sensor.)
5. Hold the START button to display the drum
RPM’s; the display will read “r##” where ## are
the RPM’s. (Only available on tumblers with the
rotation sensor.)
