[Solved] Amica ZIM629E Dishwasher - Error E8, Troubleshooting, Divider, & Documentation Help

Dishwasher as in the topic, I have not seen it yet. Error E8 I did not find the error codes of this model, the design is significantly different than in the ZIM629 model
I would be grateful for information about the error codes and any suggestions. The dishwasher starts, works and apparently at the end of washing an error code pops up. He drains the water. Washes inadequately. I expect litter or glasses in the system and problems with the divider, but I cannot find good documentation and am not sure about the solution of the divider on this model. Amica No. 11001081448255 (1100108)
Maybe someone has full documentation of the model, because in the one I have there are no specified parts (no table of descriptions for drawings).
Thanks in advance for your quick help.

According to user manual page 20 (in other versions page 22): E8 Failure of the spool valve / override valve - Contact service

Thank you very much, which is exactly what I expected, I like to be prepared for the visit. Best regards.

After removing the three-way valve of the pump, despite careful removal, glass spilled out of the remaining water unnoticed on the towel underneath, the initial examination did not indicate where the immediate problem was. The glass was found (spotted) immediately after electrical testing of the valve "short" operation.

I will also provide additional information that was difficult to obtain, because in this model there are (were) two three-way valves depending on the production date
Until 20.VI.2016, the valve with the symbol 1030669 was used
After this period, the valve found under the reference number 1035687.
Best regards. Subject to be closed

Hello and I'm connected to the topic.
The same dishwasher ZIS 2612, the fault was also E8, the error was sporadic. The removed three-way valve was mechanically undamaged, also inside was clean and free of loose impurities. The motor has been checked (230V) works. The microswitch should work zero-one, i.e. on-off, it worked, but on disconnected contacts where it should be 0, it showed 2.2?, and then ascending or descending.

Replaced the microswitch with a new one, the cost in the store ... a trifle - PLN 3, and the entire valve 350! After replacement, the dishwasher works.

Now, a brief description for the uninitiated on how to do it.
Well, when we have the valve removed, and it is located underneath (the dishwasher should be placed on its side) between the salt container (plastic) and the washing pump motor. The engine can be seen at the bottom. Unfasten the ankle, unfasten (with pliers) the clamps on the two hoses (one at the back), unscrew one screw and take out the valve. Then, on the table, we take off the engine, it is grasped with two black paws. It is important because under the motor there is one of the two screws holding the housing and the gear set. After unscrewing, turn the black casing downwards and gently fold back the 4 paws and take the pump off the gears. Next to the middle one there is our culprit micro switch with the DB1 lever. The entire repair, including disassembly, contact replacement and assembly, took me 1 hour.
