Help needed, Bosch dishwasher ⇐ Bosch

[Timur]

Good afternoon, please help. Bosh dishwasher, I don’t know the model - it’s not written on the case, it’s about 7 years old. When turned on, it buzzes, the cold water meter spins for a short time, then the relay starts clicking, but no water splashes. After ten minutes it becomes warm inside. The filters are clean - washed. I unscrewed the screw under the filters, removed the pump cover - the pump rotates spring-loaded, there is no interference. What could it be??
