As the drum reaches the fully opened position, details on the drum bridges hit the door
grabber, causing the motor to stall and the drum to stop. The drum is now in a fully
opened position, where the user can load or unload garments from the dryer.
The dryer electronics can determine whether the drum has reached the correct
position by way of the optical sensor attached to the Sensor board, which uses the
dimples on the drum end outlet to determine the drum position.
4. Provided there is no failure in extending the grabber, the drum door will be opened.
However, if a failure is detected in the actuator’s movement, the drum will immediately
stop. The dryer will then attempt to retract the grabber. If the grabber is successfully
retracted, the sequence will repeat from step 1 of this opening sequence. However, if
the actuator fails to successfully move the grabber after repeated attempts, the sensor
module will stop the drum in its closed state and a fault code will be displayed. Five
attempts are made to open the drum door before flagging the fault.
5. The lid lock will be released.
When the power is first switched on or restored after interruption:
In normal circumstances where the previous cycle was completed successfully, when
power is reapplied to the product, the sensor module will assume the door is open and the
machine is at rest. In all other cases it will either continue operating or return to the
“home” position so that the drum door is open and the lid is unlocked. If for some reason
the drum door is not open, then the operator will need to first start, then pause the
machine to return it to its drum open position. When the dryer recommences operation,
the sensor module must allow for the situation where the drum door may be part way
through an opening or closing sequence. In order to do this without the risk of damaging
any of the mechanical parts, the sensor module executes the following sequence:
Engagement Ribs contacting Hinge Arm
Hinge Arm and Locking Bar are unlatched by
the Door Grabber
Bridge Channels
Door Partially Opened
Drum is stopped by the Door Grabber
