I have an AEG F55002ViOP dishwasher. It's making a strange grinding sound and showing error code 30. Can anyone advise how to solve this please.

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.

there is water in the base of the macine. lean it over to the side to get all of the water out then try again.

i fixed the problem by tipping the machine over slightly, as suggested by other members, about a pint of water came out the bottom and it now seems to work perfectly.

SOURCE: Bosch Dishwasher model : SHV4313GB/17 The

I have a SHV. My sink drain backed up, and the water accumulating in the sink then migrated to the dishwasher, through the drain pipe, causing the dishwasher to fill up and, it turned out, overflow a little. When I turned on the dishwasher, the water drained, but no new, clean water came through the hot water pipe. The drain just kept running, but nothing else happened.

Here's what happened. Under the main chamber of the dishwasher, by three inches or more, is a white plastic tray. It sits almost at the floor, and it may not be obvious that it's a tray capable of holding water. The overflow water spilled into that tray, which in turn caused a float in the far left side of the tray to lift (the way a toilet float lifts when the water fills in a toilet tank) and shut off the water intake valve (like the toilet float shuts off the toilet water flow). So long as that valve is closed, your machine will not run.

STOP: disconnect power supply at this point for safety.

To see the white plastic tray and thereby fix the problem, you'll need to take off the BLACK TOE-KICK (attached on my unit by two star-head screws at its bottom) and, possibly , the OUTER PANEL OF THE DISHWASHER DOOR (in my case, a custom wood panel (attached by a few screws through the inner side of the door, two screws that are accessed by popping off little--smaller than a dime size--covers on the sides of the doors, and then the door panel lifts up and out). (I took the outer panel off, but I can't remember if I would have had to reach into the white tray without doing so.)

Once you do that, you can see the white plastic tray. It doesn't come out--at least not without removing the entire machine--so try this. You can take your fingers and feel over and into the tray. You'll probably feel the water--I did. Look at the far left of the tray with a flashlight. Back there you'll see a flat, round, 3-inch diameter piece of white plastic sitting at the bottom of the tray. To its center is a generally U-shaped lever looking device, which, at its far left end, is connected to a red stick pointing up into the machine. When water goes into the tray, the float rises, causing the U-shaped lever to rise, causing the red stick to raise, which (though I couldn't see it) causes an electrical signal to run to, and shut, the valve for your water intake.

I took paper towels, and then a narrowly cut sponge, to sop up the water in the tray. I then took my shop vac and, using it as a blower, blew what little water was left right out. You might be able to use a hair dryer, but first sop out what you can or it'll take forever. Once you've done that, put everything back together and plug your dishwasher back in. My buttons are at the top panel. To reset, hold down the two buttons marked for clear drain for three seconds and release. You should be able to start up then. It took 15 seconds before the water started to run, but it did and the machine works fine again.

Interesting note: The valve that stopped the water from flowing in automatically opened once I got the water out of the tray. You don't need to reset the valve.

Good luck.

Sounds like the Anti-Flood system activated (polystireen float at base of machiene coupled to a micro switch) the purpose of this system is to put the drain pump on and stops any other function on the machiene. The anti lood system activates when any amount of water appears on the bottom (caused by leaky pipe / blokked pipes / spills etc.) . Dry the water and rectify the leak. This should solve the problem.
