Dishwasher fail on C3 (leak prevention system)

15-26yrs?

I have a similar issue on oko favorit 50700. I have checked the flow from the inlet hose into a bucket and it really seems ok, so I think maybe a problem at the inlet to the machine? Plea update if you get a fix!

AEG OKO FAVORIT 40300 When switching dishwasher on no water is flowing into the the dishwasher

Please help

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

I don't understand why replies talk about the C2 and C3 errors... The problem is C1! I have the C1 error. I start a programme, it does the draining cycle to check empty then starts filling. MI can hear water entering but it sounds slow at a low flow rate. If I leave it going, eventually the programme stops and the error is displayed: C1 Opening and closing the door allows the programme to continue. I get the error after the various stages of the programme, when it is filling for the next wash or rinse. So it's 4 or 5 times I think during the programme. Now, if I help the filling... When the appliance is filling, I open the door, and poor in a kettle or two of water, then the error does not happen (the fill is within the time expected by the appliance?) So I am thinking one of two things is wrong: 1) I have a flow rate problem BEFORE the water connection to the appliance. E.g. It is blocked somehow. 2) There is something which opens/closes the "tap" within the machine which is causing the flow rate to be low and it does not fill quickly due to that. No idea which of these two, but I did disconnect the hose of the supply and check that water flows quickly from it into a bucket, so I am thinking there is something inside the machine which "opens the tap" and it's not doing a good job of it. Anyone got a clue?

probably the main module ie the pcb you were looking at

C3 error means that there is water at the bottom of the dishwasher. Unplug the dishwasher, slide it forwards and push it back. So it stands on the 2 back knobs. Do this atleast at a anle of 45 degrees. You will see water flowing at the floor.
If this happens often you have a leak somewhere. Time to cal the technician then.

Hi i just repaired mine. There was no fuse in it i found the timer control has a tranformer that goes from 240 volt or 115 volt in USA to 12 volts only the on off switch worked .

The dishwasers have heat (inductive) elements in line with the top sprayer hose and is about +/- 15 cm long and has an electrical push on clip at the side of the device.
