I disassembled the accumulator. It turns out that the pump consists of plastic and is driven by an electric motor. The conclusion suggests itself that the device is short-lived. I tried to adjust the pressure switch, but to no avail. Nothing happened. There is no time for repairs. I’ll try to repair it for a year. There is no information on the repair of vacuum sealers on the Internet. It’s up to you to buy or not to buy. I’ll supplement my review. I disassembled it again. the relay with a screw for adjusting the operation of the relay. Now the accumulator is working. I think that the native studs were short and poorly soldered to the board. I am not a radio electronics repair specialist, but God helped me.
