As of the morning of January 21, this node “works normally,” the TASS propaganda agency writes, citing the press service of Roscosmos. The problem was solved by restarting the system.
Last October, Electron-VM had to be disassembled under the supervision of ground engineers. While troubleshooting work was underway, oxygen production was transferred to the American backup system in the Tranquility module.
The system also crashed in December.
The principle of operation of the Electron-VM unit is electrolysis of water with an alkaline electrolyte in a flow-through electrolyzer. Oxygen is catalytically purified. Productivity – from 25 to 160 liters per hour, which is enough for breathing up to six people. In parallel, 50 to 320 liters of hydrogen are produced per hour. The system has not been changed since the creation of the ISS. From time to time, such oxygen generating devices fail. For example, 10 years ago the crew repaired Electron-VM for several days.
The crew’s negotiations with the Earth are also being conducted via an open channel, NASA broadcasts it continuously on YouTube. In Russia last year it was proposed to do this over an encrypted connection.

The ISS has long been unable to accurately localize on the Russian Zvezda module the place where the atmosphere is leaking overboard. It may need to be completely isolated.
