Mike N. for Model Number MAH4000AWW Our washer works fine, going through all of the cycles. It just doesn't turn off when it's done. You have to hold down the start/stop button for it to stop, otherwise it stays on forever and the drum turns every couple of minutes. I replaced the motor/circuit board several years with the updated one but it didn't resolve the issue. I'm thinking it's the main board but want to verify before I order one.
Answer Hello Mike, This will be one of two issues: the black and grey wires are switched on the machine control board line relay or the contacts in the line relay have welded shut. This line relay is the black box with two wire terminals on it on the far right of the machine control board that is in the control panel. It is just to the left of the power transformer. The black wire should be connected to the terminal marked "COM" and the grey wire should be connected to the "NO" terminal. If they are swapped, this powers the machine without the control having to energize the line relay. If the contacts are stuck, the board WP22002989 will have to be replaced to correct the issue.
