About mid cycle, a significant amount of water leaks out of the bottom. No error message comes up and the machine continues functioning. Machine is AEG oko lavamat 72640

Could be a hose split or leaking underneath or even the pump might be leaking,check hoses going to the taps also.

What type of machine would help

take lid off and put mechine on wash look out under soap despencer drawer for water to start with then get back

Hi IE means Inlet Error. The machine thinks that it is not filling (as a certain time has passed without reaching level it wants).
This makes sense if water is running out the bottom.
You will need to find the leak. Maybe the tub to pump hose, or the drain pump itself. Once you stop the leak and the machine can fill in the correct amount of time, you shouldnt see the IE error any longer.
Cheer

see this causes, and fix it. God bless you
If the washer stops mid cycle the timer might be defective. This part is often misdiagnosed, check other components before replacing this timer.
f the washer stops mid-cycle the main control board might be defective. This is not common. Check other causes first such as the lid or door switch and other components
f the washer stops mid cycle the water inlet valve cold water side may have failed. Most washers have a cold water rinse and so if they can't fill with cold water they just sit indefinitely waiting for the cold water to enter. If there is cold water to the water inlet valve and the cold water works in other parts of the cycle - or to make warm water - the valve is not the problem.
If the washer stops mid cycle the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design
If the washer stops mid cycle the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

This is a really common problem that most people send hundreds when they can fix it themselves. Power off your washer, put it on its side. Your going to see four to six silver bolts with hex heads located in the center holding in a plastic device known as the filter assembly. Remove the screws and find any hair inside the assembly. Remove the hair and put the screws back in. Even the smallest amount of hair inside the filter/drain assembly will cause this problem. PRESS AND HOLD POWER BUTTON TO RESET THE ERROR CODES

It's most likely a leaking water pump.

I have the same unit, I had to replace my drain pump and clean the entire machine out. THis unit has many design flaws however once they are corrected with new parts it is a good machine.

out the bottom of door?? no through the bottom panel???. check the rubber door seal for rips or tears pull it back and look around entire circumference. smalll rip in very front of seal where door should close against will cause leak for sure

Hello,
This error code (C3) means your water sensor has detected a leak. it will stop when the sensor is dry.
Try getting the water out of the trap door and letting the machine dry.

I would also unplug it for secirity reasons.

Basically your water pump is getting tired or the sensor is dirty. Try cleaning the sensor or else you may have to change the pump.

Good Luck!!
