Detergent/Softener Level not Detected
Perform the following checks if the washer cannot detect the
level of the detergent or soener in the reservoir.
1. Open dispenser lid on top the washer/dryer and remove
the bulk dispenser container. Remove both the detergent
and soener lters and clean thoroughly with warm
water. Reinstall both lters.
2. Reinsert bulk dispenser container and verify it is fully
seated in the dispenser cavity. Close the bulk dispenser lid
and retest.
¾ If detergent/soener level is not detected, go to step 3.
¾ If detergent/soener level is detected, go to step 11.
3. Open dispenser lid and remove bulk dispenser container.
Save customer’s detergent and soener in spare
container(s). When empty, you should ‘hear’ the oats
moving up and down when the container is rotated
(see Figure 3). If stuck, thoroughly rinse both container
reservoirs with warm water. Fill reservoirs with water to
test oats. Reinstall bulk dispenser container in dispenser
assembly and check for proper operaon.

¾ If oats are damaged, replace the enre bulk dispenser
container. Container is not serviceable.
¾ If oats are working, but detergent/soener level is not
detected, go to step 4.
4. Unplug washer/dryer or disconnect power.
5. Gently lay washer/dryer on its right side to access the
ACU. Remove AC shield and ACU cover.
6. Visually check that the J12 connector is inserted all the
way into the ACU.
¾ If visual check passes, go to step 7.
¾ If connector is not inserted properly, reconnect J12 and
retest.
7. To test the detergent level switch, disconnect J12 from
ACU. Using an ohmmeter, connect leads across pins 1 and
2 of connector J12. With the bulk container removed, the
reed switch should read open.
8. While watching the ohmmeter, move a magnet around the
oor of the bulk dispenser cavity (front for detergent). The
magnet should close the reed switch (less than 3 ohms).
¾ If the resistance sll reads open, replace the enre bulk
dispenser assembly.
9. To test the soener level switch, using an ohmmeter,
connect leads across pins 3 and 4 of connector J12. With
the bulk container removed, the reed switch should read
open.
10. While watching the ohmmeter, move a magnet around the
oor of the bulk dispenser cavity (rear for soener). The
magnet should close the reed switch (less than 3 ohms).
¾ If the resistance sll reads open, replace the enre bulk
dispenser assembly.
¾ If the preceding steps did not correct the problem,
replace the ACU.
11. Unplug washer/dryer or disconnect power.
12. Reassemble all parts and panels.
13. Perform the Service Diagnosc Mode Tests on page 2-3 to
verify repairs.
