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. 

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. 

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.)
