Out of Balance Mode

1. Before spinning, control will initiate a short agitate cycle to re-distribute clothes.
2. Spin cycle begins. At @ 100RPM, control will sense for an unbalanced load.
3. If an unbalance is sensed, the control will go back to step #1, add time to timer

and try again. If no unbalance is sensed, accelerate to @ 300RPM.

4. At @ 300RPM, control will again sense for an unbalanced load.
5. If an unbalance is sensed, the control will go back to step #1, add time to timer

and try again. If no unbalance is sensed, accelerate to @ 650RPM.

NOTE: Control will keep trying steps 1 through 5 until it is successful in accelerating
past 300RPM or until a total of 12 minutes for the middle spins or 34 minutes for the
last spin has been added to the timer. At the 12 or 34 minute point, the control will
quit trying and move to the next cycle or stop operation if it was the last spin.

6. At @ 650RPM, if OoB phase is greater than set limit, the control will finish out the

the spin cycle at this speed. If it is within limits, it will accelerate to @ 1150RPM.

7. At @ 1150RPM, if OoB phase is greater than set limit, the control will finish out the

the spin cycle at this speed. If it is within limits, it will accelerate to @ 1350RPM.

8. At @ 1350RPM, if the OoB phase is above the set limit, it will de-accelerate to

@ 1150RPM and continue at that speed until cycle times out.

NOTE: Control will execute the above scenario for each spin in wash cycle.

If 34 minutes needs to be added to timer after the final spin the control will
log an “UE” error code to the service mode.
