Main hose blocked so flooded dishwasher blockage

Error code F6 E1 on a Dishwasher ADPU 701 WH typically indicates a problem with the water pump or drain system. It is possible that the dishwasher stopped mid-cycle because the pump is clogged or the drain is blocked.

To drain the machine, you can try the following steps:

Unplug the dishwasher: To ensure your safety, unplug the dishwasher from the power outlet before attempting any repairs.

Locate the drain hose: The drain hose is typically located at the back of the dishwasher, near the bottom.

Detach the drain hose: Use a pair of pliers to gently loosen the clamp that secures the drain hose to the dishwasher. Then, carefully remove the hose from the dishwasher.

Place the drain hose in a bucket or sink: Position the end of the drain hose in a bucket or sink to allow the water to drain out.

Check for blockages: Inspect the drain hose for any blockages or debris that may be causing the error code. Use a small brush or toothpick to remove any blockages.

Reattach the drain hose: Once you have cleared any blockages, reattach the drain hose to the dishwasher and secure it with the clamp.

Plug in the dishwasher: Once the drain hose is securely in place, you can plug the dishwasher back in and try running a cycle to see if the error code persists.

possible drain hose blocked or bad flood sensor

I have seen the float in the drip pan stuck in the up position before. If this happens, it wont let your machine fill. You will have to check underneath to confirm if this has happened.

Have you tried unplugging the dishwasher power cord from the outlet, waiting 30 seconds and plugging it back in?

Hi, E2 means that anti flood device has been activated. The machine has overfilled.
Check in the base (under the bit you put the dishes in) to see if it's flooded. The causes for overfilling are blockages in the metering tank, blockages in the system hoses.
Drain the water out of the base and try the machine again. If it overfills you'll need to take the machine out, do a fair bit of dismantling to get at the hoses etc. to clear the blockages.

It is possible that there is a block in the drain hose which prevents water from previous wash to fully empty.
This means when you start dishwasher next time it overflows and causes the dishwasher flood switch to trip and shut dishwasher.

You will need to check the drain hose for any blockages and clear it.

This is a typical Anti Flood system activation. This system activates when water leaks onto the floor of the machiene due to a leak fault (pipe/hose clamp/ partly blocked pipe). The machiene automatically switches to pump out mode and stops water inlet. The anti flood system is a polystireen float / micro switch at the base of the machiene floor. Dry the floor and drectify the leak and it should work.

Do the following.

1. Switch off the machine, unplug or disconnect the mains AC power to the machine and turn off the water supply to the machine.
2. Remove the filter access panel.
3. Remove the filter and make sure that the filter is not blocked and is clean and clear of all debris. Clean as required. Note that depending on the machine type you may get a lot of water coming out of the filter when you remove it if the machine has not drained successfully. Note that if the machine has stopped and not fully drained then you may be able to drain out the excess water by removing or disconnecting the waste hose and laying it on the ground in a tray. It may take a few minutes to empty but it will save a small flood.
4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked.
5. Also check that the main waste drain pipe, if you use one, is not blocked and clean if required.
6. Reconnect the power and switch the machine on.
If the problem persists then do the following.
7. Switch off the machine and disconnect the mains power.
8. Check the electrical connections at the pump and make sure it is operational.
9. Remove the connecting hoses, and expect water to drain out and make sure the pipes are not blocked with debris or any object blockage.
10. Makes sure the pump appears clear and that the impeller looks in good condition.
11. Reconnect the hoses and then reconnect power and switch the machine on.
12. If problem has not been corrected, then remove the pump and check that the drive coupling to the motor is OK and that the motor turns OK. If all is well then replace the pump.

4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked or restricted.
5. Also check that the main waste drain pipe and one way valve to a sink waste connection if you use one, is not blocked and clean if required.
6. Access the pump from under the lower rotor arm and protective grille and check that the impeller is free to move and is not clogged or restricted by debris or sludge. Clean as required.
7. Reconnect the power and switch the machine on.

hi
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor. 
else you need to REPLACE THE PCB POWER CONTROL BOARD
