Pump continually running with F2 displayed.

Try these... -Clean out the drain pump inside and below.

- Pull the suction boot off the drain pump, clean out any gookus.

- Blow through the drain hose starting from the connection at the pump.
make sure it is not clogged follow the line from under the sink and disonnect it from under the sink and make sure it is clear
- If all else checks out, replace the pump.

The Duet hides the pump/filter access behind the lower panel. Most LG, Miele and ASKO washers have it right up front for easy access. I guess keeping such a base element out of view helps sales.

Long Drain error code.
If the drain time exceeds 8 minutes, the water valves are turned off and "F/02" is flashed.
Press, PAUSE/CANCEL twice to clear the display.
NOTE: After 4 minutes the "Sud" error will be displayed, then 4 minutes later the "F2 error code" will be displayed.
Potential Causes:(1) Check the drain hose and make sure it is not plugged or kinked.
(2) Check the electrical connections at the pump and make sure the pump is running.
(3) Check the drain pump filter for foreign objects.
If the above does not correct the problem replace the pump

Drainage problem of some sort is usually the cause. Could be blockage before your drain pump, in your drain pump, or in your drain hose. One possibility is that you just installed a garbage disposal and forgot to remove the "knock-out" plug for the dishwasher drain line. Another cause can be that you have not looped your dishwasher drainline under your sink and water from your sink is flowing back into you dishwasher. You must attach your dishwasher drain line under your sink so it is higher then your sink drain lines, creating a trap for your dishwasher. Your drain sump could be plugged, not letting the water get to your drain pump easily. This is caused by not getting loose or hard debris off your dishes before putting them in the unit. Also make sure your drain pump is getting the right voltage when it is supposed to.God bless you

As far as draining the backed up water you may have to run a short cycle wash to help it. In California homes we have a by-pass vent which runs from the dishwasher drain hose up to a port in the kitchen sink. From there it is attached to the side port of a garbage disposer. In the event of a backwash the by-pass vent is high enough that it can't reach a level that wiould flow back into the dishwasher.

see this causes and fix it. God bless you
Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Drain Solenoid Kit If the dishwasher won't drain, the drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced. The drain valve is not repairable.
Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

Drain Hose If the dishwasher won't drain the drain hose might be clogged. Remove the drain hose from both the dishwasher and the sink drain to clean it out. The most common place for an obstruction is at the garbage disposer.

Check Valve If the dishwasher won't drain the check valve might be stuck closed. The check valve is a small plastic device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is the device that the drain hose is attached to on the dishwasher
Check Ball If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

Hi
Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.

Hello

If the water won't drain from the dishwasher, first manually remove as much water as possible and then check the sump area for paper or any other large object. Make sure the door is properly latched. The pump will not drain if the door is not latched properly. Check the belt, drain line, air gap, drain valve and solenoid assembly, the motor, and the pump. If your dishwasher uses a belt to drive the pump, and it has broken or come off the pulley, replace it.

A cup or so of water in the sump area of your dishwasher is normal. It is there to prevent the seals from drying out. The dishwasher will pump this old water out before beginning to wash.

If you have recently installed a garbage disposer in your home, make sure that the drain plug on the disposer has been removed. It's just a little plastic piece that blocks the hole where you hook the dishwasher drain hose. If your dishwasher drains through the garbage disposer, you need to run the garbage disposer before you run the dishwasher to make sure that the drain is clear.

There is a drain hose between the drain valve or pump and the garbage disposal or drain line. If an obstruction has blocked this, then your dishwasher won't drain. The drain hose is connected by clamps to the drain valve and the disposer or drain pipe. Remove it and visually inspect it for a clog or a kink. Try to remove any debris. If it is in good condition, just put it back on, and if not, purchase a new one to install.

If you don't have an air gap in the drain line, at least use a high drain loop. Making a large loop about 18" off the ground with the drain line can prevent any back flow into the dishwasher from the sink.

If you have one, the air gap will be located on top of the sink. The air gap is there to prevent any siphoning of standing water from the sink. When your dishwasher drains, the air gap diaphragm will form a seal and allow the water to drain properly. If the diaphragm in the air gap is faulty, it's possible that water can leak onto the cabinet and into the sink area. When this happens, then the air gap must be replaced.

Like the inlet valve, there is also a drain valve on most models. When no power goes to the drain valve it remains closed and prevents water from leaving the machine. When the valve receives power during the drain cycle, the solenoid opens and allows the water to leave the machine. If your drain hose is attached directly to the pump, you don't have a drain valve. The motor simply reverses and the pump sends the water in the opposite direction, which is out of the machine.

If the motor doesn't turn or work properly, the dishwasher may not drain. Make sure you have power to the unit. If you notice that the motor hums but won't turn, it could be seized, and you probably need to replace it.

Small objects can sometimes get stuck in the pump. When this occurs, you'll need to open the pump and remove any debris buildup. The dishwasher pump is usually mounted directly to the motor and runs off the motor as well. The pump is also attached to the bottom of your dishwasher and pushes the water from the dishwasher.

Hello, Thank You for using FixYa. I will be helping you today.I would start where your drain line connects to the house drain,This is where most blocked drains happen. Disconnect the drain line and put it in a bucket and try to drain the dishwasher. Chances are its blocked somewhere you just have to find it.
Thank You and please ACCEPT my answer and Rate my answer if it was helpful..

Hi.

The machine is telling you that there is overfill, f2 and 4 are faults with overfill system. Lights blinking, pump running and controls dead also indicate an over fill fault :

"1. Disconnect the power to the unit

2. Remove the lower access panels and check the tray under the dishwasher (you will probably find it is full of water)

3. Use a towel or a sponge to remove the water

4. There is a float that should stop the operation of the dishwasher and run the pump if water is in this tray. Check this pump to see if it is functional

5. Test the dishwasher

6. If there are no leaks from the dishwasher into the pan, check the drain hose under the sink

7. THE DRAIN HOSE MUST RUN UP TO THE TOP OF THE UNDERSIDE OF THE COUNTERTOP THEN DOWN TO THE DRAIN. (If the hose is not set up like this, water from the sink drain will flow into the dishwasher and overfill the tray"

Here all diagrams.

Regards.

Ginko.
