I get an error code: F dU and my washer won't drain properly
I have had my whirlpool duet front loading washing machine for almost 5 years. It has worked fine up until now. It ran the wash cycle just fine, but when it came time to drain and rinse and spin my clothes, it quit and gave me an error code F dU. I can't get my machine to drain. I checked the drain hose for blockage, but there wasn't any blockage there. I tried to unlock the front door to see if I could remove anything blocking the drain hose from the inside but I could not get my machine to even unlock. I need to know how to access some kind of a manual over-ride on this locking mechanism so that I can retrieve my clothes before they are damaged and/or begin to smell because I can't drain the water from my machine.

I too, had the same issue with the door not opening. My solution was to unplug the power cord and then plug it back in and press the green button's as if to start a cycle and while it starts putting water into the washer I put my knee and weight into the door lock area and held pressure from my knee and press the red stop button until the lights went out, and I took my knee off the door lock area and opened the door!!! No taking off the lower panel.
If this works for you too please email me firstname.lastname@example.org.

FDU is Door Unlock error.
A Door Unlock Error occurs if the door cannot be unlocked. It will try to
unlock the door six times before displaying the error code.
Possible Causes / Procedure
• Door lock mechanism is broken.
• Door switch/lock unit failure.
1. Check door switch/lock unit for foreign objects.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the door switch/lock unit and Central
Control Unit (CCU).
NOTE: The door switch/lock unit can be manually unlocked:
To manually unlock the door lock system, perform the following steps.
1. Unplug the power cord from the outlet.
2. Remove the lower toe panel.
3. Reach up along the inside of the front panel and locate the bottom of
the door latch assembly.

tab. Gently pull the tab down approximately 1/4 inch, or until a click is

Whirlpool Duet front-load washer F02 usually means it is taking over 8
minutes for the washer to sense that the rinse or wash water has
drained, which either means that the drain/filter is clogged or the
pressure switch/tube is clogged (causing both the washer to over-fill
with water and not sensing that water has drained).
To clear out
the drain/filter, tilt the washer backwards a little for easier to the
kick-plate and support the front bottom with a wood block or similar,
remove the front kick-plate's (3) retaining screws and swing the
kick-plate up out of the way. The filter drain is behind the white knob
in the center, be prepared with something to catch any remaining water
and lots of towels to soak up any spills, and turn the knob
counter-clockwise to remove the filter.
Was the error code F01? If it is ther error code means EEPROM ERROR
A communication error between the Central Control Unit (CCU) and the EEPROM onboard the CCU occurred. and or
PUMP DRIVE ERROR
The pump driver fails to activate. and or
MAIN RELAYS ERROR
One of the main relays is not working properly.
Could be cause by a power glitch. unplug unit wait 10 seconds and plug unit back in. If code returns replace Central Control Unit (CCU)
If the drain time exceeds 8 minutes the water valves turn off. After 4 minutes the “Sd” error will be displayed, then 4 minutes later the F21 error code will be displayed.
Press PAUSE/CANCEL two times to clear.
1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 5. If the above does not correct the problem, go to step 7. 6. Unplug washer or disconnect power. 7. Replace the pump.
Alternative Procedure: If the machine cannot be forced to its diagnostic mode then:
1.Disconnect the washer from the power supply and water supply. 2.Remove the top panel by taking out the three screws in the back of the washer. The pressure switch is right on top. 3.Remove the Molex connector from the water level switch / pressure switch. Refer to the picture below. 4.Reconnect the power supply but not the water supply. 5.Power the machine. The machine will enter diagnostic mode. 6.Power off the machine. 7.Replace the water level switch / pressure switch. 8.Reconnect the water supply. 9. Power on the machine it will work without error
Careful of overloading the front-loading washers. Too much of this will result in the bearings in the drum to go bad. When this happens, the rpms on the drum slow down due to belt slack. You can only see this with the back off of the unit and in the middle of the cycle. They do not sell replacement bearings...you'll have to buy the whole drum (bearings pressed inside) and for 1/2 the cost of a new washer. I hate front-loaders. I'll never buy one again.
serial communication error between central control and motor control. Check connections at ccu (top front right corner) and mcu (bottom by motor), check belt drive for wear. Did motor run ? Any other codes in diagnostic? (any one modifier button 4 sec on 4 secs off 5 times.) F codes are failures and C codes are portions of test cycle(automaticly run)
