Ошибка cl2357

Good day, everyone. I recently purchased a Creality Hi Combo. At first, everything was going great. But all good things come to an end. An error started popping up (the bed hasn’t reached the maximum Z‑axis height. Check and restart. What could be the problem? I replaced both sensors at the top. It still doesn’t help. At what level should I set the Z‑axis to start the installation after resetting? Thank you in advance.
