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.

F9 is an Overflow Condition error. If the Overflow contact on the pressure switch is closed for more than 60 seconds an Overflow condition will occur. In an Overflow condition, the Door may remain locked, and the Drain Pump may run constantly, even if PAUSE/CANCEL is pressed twice and the Display is cleared. Unplug the unit to service. You will need to check to following:
1. Check the drain hose and make sure it is not plugged or kinked.
2. Check Wire Harness connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU).
3. Check/Clean Drain Pump Filter of foreign objects
4. Check for Drain Pump Failure.
5. Check the Inlet Valve for proper shut off
6. Check the Pressure switch for proper operation.
1. Check the drain hose by removing it from the standpipe and pull a vacuum on it with a shop vac. It could be that you have an obstruction somewhere. You may have to check the drain pump and the drain hose just prior to the drain pump as well. This is the hose that attaches to the bottom of the tub. This area can get clogged with debris
2. Unplug the washer and remove the kick plate and top panel. Check for any loose connections at the drain pump, pressure switch (located in the right rear of the machine), and the CCU (located in the center rear of the washer behind the wash tub). You may have a loose or dirty connection somewhere. If you remove any connectors, make sure you write down where they go. It's best to only remove ONE connector at a time when checking the CCU. On the pressure switch, make sure the air hose is still attached. This is usually a clear or black rubber hose. With the air hose off, loose, or leaking, the switch will not work and the tub will continue to try to fill. The pressure switch can be checked by removing the the large connector plug from the front of the CCU at the very LEFT. Readings across pins 1 to 2, 3 to 4, 4 to 5, and 4 to 6 should ALL read 0 ohms.
3. The drain pump. Remove the clean out cover on the pump and check for debris. Make sure you drain the water from the drain lines, pump and hoses PRIOR to removing the cover. Otherwise, you will have about a gallon or so of water to clean up. The shop vac method works great for this. If the pump is running and clear of foreign matter, the pump is probably not the problem. A meter reading across the pump motor windings at the connector plug should be about 15 ohms.
4. The inlet valve. If the inlet valve would fail in this manner, the tub would be trying to fill with water all the time and not shut off (even with the washer turned OFF). You need to ask yourself if you find standing water in the tub when not in use. Replace the water inlet valve if this is the case. Readings across the HOT and/or COLD solenoids should each read about 800 ohms.
5. The suds error. This occurs when air from too much detergent gets into the drain line. If you are using HE detergent (which is great, because on the newer models NOT using HE detergent voids your warranty), but HOW MUCH are you using? Some things to consider:
a. Do you have soft water? This can actually cause the soap to suds better making the need to cut back on how much you use.
b. Look at the detergent container. Is it double or triple concentrated? Some detergents are sold as extra concentrated which means you need to cut back on the amount you use. Not doing so can cause the water to over suds.
c. What size loads are you using the detergent in? Running small loads with the same amount of detergent can also cause over sudsing.
Rule out the simple common sense things first. If everything else checks out and your problem still persists, you may have a failed CCU or pressure switch
