Hi... I just bought Electrolux Dishwasher ESF2433W. When i first time turn it on, light at "Normal" button keep on flashing with beeping sound. After checking the trouble shooting manual, it actually

E4 Overflow

Sometimes during trasport it is possible that styrofoam float mechanicaly activated overflow microswitch. So, you should check complitely overflow system.

At any time, if overflow micro-switch act and keep for longer than 2 seconds, the E4 would occur. When E4 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes (if the model with the pressure switch (83/63),drain pump would run till the pressure switch reset and continue draining for 60 seconds.) and all the other components will be stopped immediately. At the same time, the buzzer will alarm for 30 seconds and error 4 will be shown. Note: Priority level of E4 is the highest. E4 operation is valid after other error operations have done. When E4 operation has done, all the others are invalid.

I have ESF2400OW, got the same error E4 (leak) manual says to turn to service. I had made the drainage too thin near the sink, so there was a blockage from some small leftover food and water was unable to escape. I sorted out the blockage, plugged it in and turn it on for some time allowing the water in the machine to escape, dried the floor, tilted the machine about 30 degrees backwards, let all excess water drain out, plugged it back in and it worked again.
