TEST #8: Drain Pump
Perform the following checks if washer does
not drain.
1. Check for obstruc�ons in the usual areas.
Clean and then perform step 2.
2. Check the drain pump and electrical
connec�ons by performing the “Quick
Diagnos�c Test”. The following procedures
assume that this step was unsuccessful.
3. Unplug washer or disconnect power.
4. Remove top panel to access machine
electronics.
5. Visually check that the DP2 connector is
inserted all the way into the CCU. Refer to
CCU diagram.
�
If visual check passes, go to step 6.
�
If connector is not inserted properly,
reconnect DP2 and repeat step 2.
6. Remove connector DP2 from the CCU.
With an ohmmeter, measure the resistance
across pins 1 and 2.
7. Resistance should be approximately 16 Ω.
�
If the reading is infinite (open), go to step 8.
�
If the reading is correct, go to step 12.
8. Remove the front panel to access drain
pump. Verify pump is free from obstruc�ons.
9. Visually check the electrical connec�ons
at the drain pump.
�
If visual check passes, go to step 10.
�
If connec�ons are loose, reconnect the
electrical connec�ons and repeat step 2.
10. With an ohmmeter, check harness for
con�nuity between the drain pump and CCU.
�
If there is con�nuity, go to step 11.
�
If there is no con�nuity, replace the lower
machine harness and repeat step 2.
11. With an ohmmeter, measure the resistance
across the two pump terminals. Resistance
should be approximately 16 Ω.
�
If the reading is infinite (open), replace the
drain pump assembly.
�
If the reading is correct, go to step 12.
12. If the preceding steps did not correct the
drain problem, replace the CCU.
�
Unplug washer or disconnect power.
�
Replace the CCU.
�
Reassemble all parts and panels.
�
Perform the “Quick Diagnos�c Test”.
TEST #9: Flow Meter (Steam Model)
This test checks the electrical connec�ons
to the flow meter and the flow meter itself.
1. Perform the “Quick Diagnos�c Test”.
If error code F8E4 is generated,
the washer is detec�ng less than 0.1L of
water a�er 30 seconds of star�ng the test.
Go to step 2.
2. Did the valve(s) turn on and was water
seen and heard entering the drum?
�
No, the valve(s) did not turn on.
Go to TEST #6: Water Inlet Valves.
�
Yes, the valve(s) turned on, but no water
entered the drum. Go to step 3.
�
Yes, the valve(s) turned on and water
entered the drum. Go to step 4.
3. Verify that the hot and cold water inlet
hoses are properly connected to the washer
and the valves are turned on fully. Ensure the
inlet hoses are not kinked or inlet screens
blocked.
4. Unplug washer or disconnect power.
5. Remove top panel to access machine
electronics.
6. Visually check that connector FM3 is
inserted all the way into the CCU. Refer
to CCU diagram.
�
If visual check passes, go to step 7.
�
If connector is not inserted properly,
reconnect FM3 and repeat step 1.
7. With an ohmmeter, check the harness
between the CCU (FM3) and flow meter
for con�nuity.
�
If there is con�nuity, go to step 8.
�
If there is no con�nuity, replace the flow
meter harness.
