“F21” is a Long Drain error. If the drain time exceeds 8 minutes this error code will be displayed. In addition, a “SUDS” error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:
1.First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
2.Check the drain hose to make sure it is not kinked or clogged.
3.Check the electrical connections to the pump and ensure the pump is running.
4.Remove the drain pump filter and check for foreign objects and/or debris.

SOURCE: WHAT DOES F01 ERROR CODE MEAN AND HOW DO YOU FIX
F01 - There may be an internal problem with the control, attempt a Hard Reset.
Hard Reset - In some cases the control can be non-functioning or may not accept activation from the control panel. To clear and restart the control follow the these steps:
* Unplug or turn the circuit breaker off for 30 seconds.
* Reconnect the unit to the power source by turning the breaker back on or plugging the unit back into the wall outlet.
* Press the Pause/Cancel/Stop button twice to clear the "PF" in the display.
* 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.
The F01 generally indicates a failed electronic machine control board.
This error code can sometimes be caused by a glitch or power surge through the electrical lines.
You may be able to clear this code by unplugging the washer for 5 minutes.
If the code returns after plugging the washer back in, then the electronic machine control board will need to be replaced.
The procedure for accessing and replacing this control board is shown in this image...

Be sure to unplug the washer before accessing internal components.
When you access the control board, I recommend transferring the wires from the old control board to the new replacement control board one connection at a time.
Once you have all of the wires transferred, remove the old control board and mount the new control board in the washer.
Reassemble and test the washer.
The "F01" error code indicates a communication error between the Central Control Unit (CCU) and the EEPROM onboard the CCU.
The "F01" can also be displayed if the onboard "Pump Driver" fails to activate.
Generally in order to correct this failure will require replacing the CCU.
There is no way to test and verify if the control board has failed.
The technical data sheet basically states to replace the CCU.

The F70 and F71 error codes on this model of washer indicates a communication problem between the user interface control board and the central control unit (main control board). These error codes can sometimes be caused by a power surge or glitch through the electrical lines. Try unplugging the washer to completely disconnect electrical power. Wait 1 minute and then plug the washer back in to the see if the fault code clears. If it does, then the washer may work normally.
If the code reappears, then you could have a wire harness connection problem, a failed user interface control board or a failed central control unit. I recommend calling a service technician to properly diagnose and repair this type of problem so that the correct component can be replaced.
Be sure your unit is plugged into a 3 prong grounded outlet as well.
F71 is a "heatbeat failure" which means that your front interface control board is shorted and will need to be replaced. it's actually fairly easy to replace and can definitely be done by yourself. To access the part, just pull the unit forward and remove the 3 screws coming in from the back of the top panel. Remove the top panel by pulling it back, up, and off. Then remove all the screws going into the top of the control panel. Remove the dispenser drawer and remove the screws coming in through the dispenser. Remove the screws coming from the inside of the dryer going forward into the control panel, then remove the control panel (it's just clipped in on the bottom. After that you can disconnect the wire harnesses to the front interface control board and replace that part.

SOURCE: Receiving Error Code F06
The error is an indication a motor speed problem. You will need to check the following:
- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).
NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.
NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.
- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.
- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.
Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 - is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.
NOTE: All the connector pins are numbered R to L.
If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.
If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.

SOURCE: elite front-load washer error code F22 then F28
This is an indication of a door latch failure and/or interconnecting wiring problem. The first step in troubleshooting the problem is to unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). This is the main "brain" of your washing machine. Sometimes these error codes are erroneous and can be easily cleared by resetting the CCU. If the error code reappears following a CCU reset, then you have a genuine problem. In addition, if the door latch remains locked following this procedure, there is a manual release you can use to open the door. Follow these steps:
1. Remove the lower panel under the door by loosening the three screws under the bottom edge on the front of the washer. HINT: If you prop up the front feet of the washer with a 2 x 4, it makes access to the screws much easier.
2. With the screws removed, the lower panel should drop down then come off. If the panel sticks, a light tap on either side will knock it loose.
3. Reach your hand up inside the washer behind the front casing on the right-hand side. This is where the door latch assembly is located.
4. At the bottom of the door latch assembly is a small pull tab. This is the manual release for the door. Pull the tab straight down and the door will come open.
If you still have the error code displayed, inspect the door latch mechanism for any broken, loose, or missing components. Next, open the top panel of the washer by removing the three screws in the rear of the washer that hold the panel in place. With the screws removed, the panel will slide back, then off. Locate the door latch on the right hand side behind the front panel. Inspect the wiring harness from the door latch to the to CCU. The CCU is located directly behind the wash tub in the top rear of the washer. Make sure all the connectors are snug and not loose or broken. In the majority of cases, a persistent error is a failed door latch. If all these preliminary checks are unsuccessful, replace the door latch. Follow these steps:
1. Unplug washer.
2. Remove the outer portion of the door bellow. This is the gray rubber boot around the door. Feel around the edge of the door bellow where it attaches to the front of the washer. You will find a wire retaining hoop in the seam between the rubber and the front case. Follow this wire hoop to the bottom of the door bellow and you will find a tension spring. Carefully, stretch this spring apart and remove the wire hoop.
3. Pull the rubber bellow from the door facing on the front of the washer being careful not to rip or tear it. Once removed, fold the rubber backwards inside the drum so you can access behind the front panel. DO NOT remove the rubber bellow from the wash tub.
4. The door latch assembly is located behind the front panel of the washer on the right hand side. Locate and remove the three screws on the washer front that hold the door latch assembly in place. The whole assembly should come free from the washer front and be held by a plastic mounting bracket and several wire connectors.
5. Carefully remove the latch assembly from the plastic mounting bracket BEFORE attempting to unplug any wires. It makes it much easier to access if you do.
6. Unplug the wire connectors using care not to break any of the wires. You may want to write them down, but I believe they will only plug into their respective slots.
7. Remove the old door latch and install the new one in the reverse order of the steps I just presented to you. Plug the wires back in first, then place the whole assembly back into the plastic mounting bracket, and then reattach to the front of the washer.
8. Now, when you get the reinstalling the rubber door boot, you may want to get the assistance of a second pair of hands as it can be difficult sometimes to manipulate the wire retainer back into place. Carefully reattach the rubber bellow to the door facing on the front of the washer first.
9. Starting at the top of the door bellow at the 12 o'clock position begin inserting the wire hoop back into the groove. Work your way around with both hands to the 4 and 8 o'clock positions. (This is where you could use those second pair of hands). While holding a slight downward tension on the wire hoop to keep it in place, pull the tension spring apart enough to snap the remaining part of the hoop into place at the bottom. Once you've completed these steps make sure the door closes and latches properly. NEVER slam a door with an electronic latch. They can break easily.
NOTE: Another method is to access behind the front panel from the top with the top panel removed. Either method works, but I have found that going through the front offers better access.
F28 is a serial bus error from the CCU (Central Control Unit) to the MCU (Motor Control Unit).
All you need is some Electronics contact cleaner spray and a 1/4 inch socket to remove the top of the machine and the back of the machine.
The CCU is the computer looking box at the top front right hand corner.
Find connector M13, (has red marking on it and only 3 wires) disconnect it by pushing the retainer tab back and pulling gently on the connector.
Spray the contacts of the connector and computer with connector cleaner.
Then re-assemble connector.
The MCU is in the back lower left corner.
Find the connector with 3 wires and red mark, and remove this connector in the same way you did the other, spray it and re-install.
Put the back and top back on.
