I am assuming that your washer is single phase. A comon reason for humming is a faulty capacitor. This must be changed by a new one.
Now one must see why the capacitor got damaged. This could happen, when the gun is closed the machine starts and goes off again in short intervals. In this case a control valve, often called the Spill Valve, needs lubrication or replacement. I prefer to replace it. Even if the pump has no faults and you have a habbit of closing and opening the gun more than necessary...the capacitor will get damaged. It is also important that if you use soap or chemicals, always rinse with fresh water before storing away the washer. Also never store the washer with pressure still built up. Always release the gun, before storing. Well in your case it must be the capacitor. If the capacitor is OK or you have changed it....try the washer without load. This can be done by removing the gun. You can leave the water supply, for this has a cooling effect during this test. Things should work fine now. If not...then the electric motor must be checked. But I repeat...the most common fault for humming is a faulty capacitor.
