The machine stopped supplying water, error E15 and the red no water supply symbol came on. At the same time, everywhere in the pan is dry, like in Sakhar, no leaks were found. As I was told in a store where they sell spare parts, 220 V should be supplied to the aquastop valve. I measured it with a tester, when I turn on the car, 220 V does not come to the valve. I disconnected the chip and wires and applied 220V from the outlet directly to the valve. The valve worked and water started flowing into the car. Those. The valve itself works properly, it just doesn’t get any voltage. I’ve read about other cars that they have a float that hangs in some position and the car produces similar symptoms. I disassembled the sidewalls and the front protection for access to the pan; I didn’t find any floats on our car. I disassembled the wiring and discovered that on the container in which the salt is poured and, accordingly, there should be water in it at all times, there is a plastic pin sticking out and a type of induction coil is put on it, from this coil there are 2 blue wires going to the chip for the "brains" Two of the same blue wires come out of the brain through the same chip and go to the aquastop valve. I’m not strong in electronics, but as far as I understand, this inductive coil should send some kind of signal to the brains, and based on this signal, the brains should supply 220 V to the aquastop valve. How to check whether the brains or this inductive sensor have failed?

Problem E15 solved. Apparently, everything fell into place due to the rocking of the car, as described in the adjacent topic on E15 on the SPS53E20 car, and the aqua stop did not want to turn on and supply voltage to the valve, because the top box with the sprinkler was removed. As soon as I assembled everything and started it up, the aquastop turned off, the valve opened, the red indicator with the tap went out, and water started flowing into the car. But after assembly, another problem came: after the program had been fully worked out, error E04 comes on and the machine does not heat the water.

The PMM had to be completely disassembled. Because While working, I forgot to close the container with salt. A large amount of salt was poured into the box and after the water dried, this salt coked the flow switching disc, which is why error E04 came on. I washed everything and put it back together, it works, no questions. By the way, during the disassembly process I found out that miracles do not happen and our car also has a float with a limit switch. It’s just that until the box separated it from the base it was not visible, it was at the very bottom in a place difficult to see. But the truth is I almost blew my mind while I separated the box from the lower base. On all machines, in all videos and on forums, they write that the box is attached to the lower base with screws. I looked for them for an hour and a half and it turned out that there were no screws on our car. We have 4 bendable metal elements in the lower base into the grooves. They are bent and due to them everything is held in place. It is convenient to bend 2 with pliers, and 2 with a narrow screwdriver.

Error E15 means that there was a leak in the pan.
