Karcher washing machine, clean

Hello, I'm offering a Karcher washing machine. I used it a few times, then left it for almost a year. Later, I tried using it again and noticed it's not drawing water. I left it like that; I haven't used it since, and I don't know what's wrong with it—whether the issue is serious or minor, because honestly I don't understand it much. I bought it at a high price, and its nozzle is included and in good condition. (The machine works, there's nothing wrong except it doesn't draw water.) Price: 250
