In reference to your Kenmore Oasis washer:
DL is a failure of the door to lock. The door must lock before any cycle begins
This condition can be caused by any of the following conditions:
The door lid is not completely closed due to an interference.
Wash media buildup is preventing the lock bolt from extending.
Machine/Motor control is detecting an open door/lid switch when it attempts to lock.
Machine/ Motor control can not determine if the door/lid switch is in a locked state.
In some cases the control can be non-functioning and not accept any activation from the customer interface (keypad), to clear and restart the control follow the below listed steps:
Unplug or turn the circuit breaker off for a 30 second period.
Reconnect the unit to the power source, breaker back on or plug into the wall outlet.
Press the Pause/Cancel/Stop button twice to clear the power failure in the display.
Try to start a short cycle to check the operation of the machine by selecting a cycle and pressing and holding the start button until the machine starts.
