Indesit DIFP 28T9 A EU Dishwasher - Unwanted Program Switch & Persistent Error 15

Hello
Patient: Indesit DIFP 28T9 A EU dishwasher

Symptoms:
- after starting the standard program (No. 3 or 5) after finishing work, it switches to program 2 itself

- Currently it does not stop working and after opening the "power on / off" LED flashes and the display shows "15"

After seeing the dishwasher, I discovered that the drain after removing the filter is standing as if it was not completely pumped out.

Anyone have an idea what to do about it?

greetings

Check that the water is drained well.

So yes: I cleaned everything that was possible inside the "washing" chamber, drain filters, "rotors" etc. After switching on again, I heard and saw in the siphon that the remaining water was pumped out. The dishwasher started as normal (judging by the sounds). I paused it after about 3-4 minutes to check if it "splashes" with water. It looked like it's ok.

Unfortunately, at some point I heard something as if a pump started working and within a few seconds the sound changed as if something properly charged the pump almost to stop.

I do not know how the dishwasher works, but I assume that it lets in water, after which something is closed-circuited, i.e. the water is pumped from the drain and again spewed out by "rotors". probably once in a while the water is completely pumped out and in its place another portion from outside comes in.

I get the impression as if something was wrong at the stage of pumping water from "bottom up".

And after switching it on again, after opening the door, the "power" indicator light was flashing and "2" on the display was lit and the "5" program was turned on when starting.

Is there a table somewhere available for possible error messages? Now I don't know if the "power" indicator should be flashing or always on or off after the work cycle ... As it worked, I didn't pay attention to it. And I assume that the numbers / numbers displayed after opening are error symbols ... But I'm not sure either.

Ok and if it takes "2" and "15" once for a change, there is still a chance to break through water inflows / outflows, are there no options and a pump?

Pump replaced and supposedly OK But there is always a but The service technician who finally replaced her was unable to answer me, what is this strange sound during "washing" in the dishwasher? The dishwasher is doing good so far so you have to enjoy it, but if I ever remember and I can catch this sound, I will boast about it
