AEG 24 in. Favorit 40850 Free-standing Dishwasher - Answered Questions & Fixed issues

AEG Favorit 40850 i30 error - this is the anti-flood error. I did the tipping-over trick, great, but for me, the problem got more and more frequent until the machine would not run. So I took it apart and this is what I found: in the drainage area, next to the water drain, is a sensor. This has been described to me by a dealer as a 'temperature sensor'. I am not sure if this controls the anti-flood system, it may well do, as it is the only one in there. However, the problem is not caused by the sensor itself - around the sensor is a black rubber grommet (seal). In my machine (4 years old) this was badly perished - the rubber had become soft and oily, and about half of it had gone. The sensor itself was covered in oily goo from the grommet. I think that bits of the grommet have been coming off and jamming in the drain, and maybe causing the sensor itself not to work properly. I changed the grommet (£5 part), and it all works great. If you want to do this yourself, follow these instructions:

• turn off power and uplug dishwasher
• you need a screwdriver with torx bits
• put lots of old towels on the floor
• remove top panel using 2 screws at rear top, then push top backwards and lift off
• remove front base fascia panel by sliding to left
  
• remove right side panel - undo 2 screws at top, one at rear bottom, one at front bottom
• front edge of side panel is wedged inside white trim - just ease it out, it isn't held in.
• open dishwasher door and push down fully
• remove curved front base panel - undo screws right up at the top of the panel, this is a tight fit against the door but you can get in if the door is pushed down fully
• tip dishwasher over onto left side
• follow the drain pipe in, this takes you to the drain pump
• if you want to check the drain pump and pipe, twist the whole pump motor assembly to the left about 15mm - there are 3 tabs that hold it in place, you need to rotate the motor past the tabs, then you can pull it out
• DO NOT remove the spring clips on the large drain pipe (50mm diameter) between the pump motor and the dishwasher drain - these are very difficult to get back on properly, and once you have taken the pump motor off you can feel right through to the dishwasher drain hole anyway.
• you can take the spring clip off the white oultet hose if you want - this goes back on easily. Check the outlet pipe with a long drain-clearing spring or similar.
• about 50mm further towards the front of the machine from the drain hose, going around the drain assembly, is the sensor described above
• this has wires going into into it, is about 25mm diameter, and you will see the black rubber grommet around it
• this is held in place with 2 plastic clips, ease these back and pull it out. TAKE CARE not to break these clips.
• If the grommet is heavily worn or perished, you need a new one. The part number is written on the surface of the grommet.
• reassemble in reverse order. Before you put the panels back on, and with the power still OFF, tip the dishwasher back upright again, open the door, and pour 1 litre of water in (this will end up on your kitchen floor, so don't put too much in).
• Check carefully under the machine, with a torch, around the areas where you have been working - the sensor and the drain pipes - to make sure there are no leaks.
• If it all seems OK, dry the floor, turn the power on and run the dishwasher. MAKE SURE you are standing on dry floor when you do this. Check under the dishwasher again for leaks.
• Let the dishwasher run a complete cycle. Check for leaks when it is pumping out.
  
• If everything seems OK, turn the power off again, put the panels back on, then turn the power back on.

Good Luck!

Activated Anti-flooding system, means water leakage in the buttom of dishwasher. Could be also: faulty Anti-flooding microswitch, floating sensor (styrofoam) blocked mechanically, wiring diagram, electronic. Dado

Dishwashers generally require a 20 Amp dedicated line. You will need to use a different circuit or upgrade the current (no pun) one. Good luck

use mseal

remove the top two screws at back, lift up about 5 degrees pull back, then you wll see the latch pins remove bolt/s,lift up trim{if it has some} and the door will open then remove inner door screws to get the front panel off to get at the latch

under the top shelf or in the top of the machine is the water rotor. remove this and ensure none of the holes are blocked, also ensure your macine is not running on 1/2 half load as this may only activate the bottom. it should be set to full load to use both. if rotor bloackage is the problem use somthing to clear it. and also check the bottom one. also remove and clean the inner filter as debris may have got past it and getting pumped to your rotors.I hope this was useful

Took unit apart and when I put it back it worked again. For how long who knows.

Access to the switch is difficult but by removing the printed circuit board, it seemed to allow the switch to work.

what is your model number is then we can get started then

In my case, it turned out that the faucet was completely clogged with scale deposits. Replacing the faucet solved the problem, so by all means, check this before you take any other action!

chik the pump moter or main filter

empty it, tip it on its back, mop up the spilt water, reload it and all should be ok. it is a recurring fault on our machine very irritating

Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

Hi

The issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with your dishwasher's filling and/or draining ability. Use your voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If your switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

check the anti flood micro switch under the dish washer.
