Hello
In fact, the i30 error means flooding
in my case, the problem was a badly fitted (or blown) gasket near the interior lamp.
First, a flash, a shot, damaged it and (surprisingly) the reaction of both the fuse in the apartment and in the stairwell. At that time, I did not expect the damage to be caused by a leak. The dishwasher works properly, despite the absence of a light
3 weeks later, the problem appeared again in the form of a terrible flash and, of course, the fuses were unplugged again (an interesting fact is that turning the dishwasher off does not disconnect the light, it is powered directly from the socket through the switch on the hinge).
Due to the inability to pull out the dishwasher without disconnecting the drain and power cables (connecting it later is very tedious and difficult - a narrow small kitchen with built-in furniture), I was forced to combine to disconnect the cable from the hinge switch without unscrewing the dishwasher - I managed)
I was slowly beginning to suspect a leak in the light ...
Another 3 weeks later the i30 error appeared
This time I had no choice but to remove the dishwasher.
Searching for leaks, I did not come across any damage ... I looked at the light out of curiosity, what happened to it ... I saw a gasket stuffed inside ... everything was clear, the light was responsible for the leak.
Currently, the dishwasher still does not have a light (damaged electronics). The gasket has been correctly installed, the housing is assembled, and additionally, it is stuck with Hybrid-Acrylic Adhesive on the inside, so that no more leakage there is ...
A moral for the future - before you dismantle the guts of the dishwasher (drain pipes, etc., first check all gaskets, etc. in accessible places, e.g. a light.
greetings
