Inconsistency between instructions and reality ⇐ Beko

[FVL]

Hello.
Dishwasher DFS25W11. I can’t adjust the water hardness level (it should be minimal), because... If, according to the instructions, you press the start delay and P+/P, and then P+/P, then what appears on the display is completely different from what is in the instructions. When you successively press the start delay button, instead of r1-5 the following appears: 1 - HFt, 2 - 1Ft, 3 - 5Ft. 4 - EEP. 5 - dno.
Please help.

Turn it on. Then simultaneously press p+ and delay start

[But]

Please tell me that the error code 1:Ft appears periodically and the machine does not start the program. After turning the power off/on several times it starts working again.
