What is the most usual reason for leakge on the AEG 6050?

the brain is gone

15-26yrs?

Error "i30" means that water remains in base because leakage or overflow. In this case, in order to prevent flooding, drain pump running continuously.
When we talk about AEG dishwasher, drain pump works even the power is turned off (must be connected to the wall outlet, otherwise anti-flooding system will not work).
The noise what you heard during operation indicates that something is blocking the drain pump.
Remedy: you should first remove the water from the bottom of the dishwasher and determine leakage then check why the drain pump makes noise.

If you work around the dishwasher, you always take care that appliance must be disconnected from the power supply.

Good luck.

This is typical of a water leak onto electrical connection OR the electrical element has shorted internaly . Check this with a Ohm meter and itshould show the problem

Empty all the water from the salt resevoir, (I used a turkey baster), then rock the machine backwards and forwards a few times and empty the last few drops from the resevoir again.

If there is water getting into the machine, then the motor, motor control unit, pressure switch, timer control and wiring harness must be tested. If the machine is a top load the motor coupler may replace the MCU of variable speed motors, that must also be tested then.

If cycle is not operating at all, with no water getting through the inlet check lid switch, door latch, inlet hose , inlet valve, membrane switch, Timer board and MCU if present.

Waited half hour; on start up F3 had cleared..pump overheat? Suspect sticky pump bearing..new pump.

This seems like the anti flood system (polystireen float / micro switch) at the base of the washer is triggered,\. This puts the washer in pump out mode and stops inlet of water via the inlet solinoid. Dry the water on the base and then check for any water leaks. (pipe leak

hi,
This 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.

post comment for more help...
good luck.....

exact same problem here, we had power cut and after power came on the pump was continuously running with error EF3 showing.
This has happened before - design error with AEG
