Makes a weird buzzing sound while in the wash

The timer sometimes will buzz like that, nothing to worry about usually, if the timer ever stops, and you can restart it by pulling out the knob and moving it a bit further in the cycle and restarting it, then your timer is going out.
But it may also be a bobby pin or something like it in the pump ,My atlantis has had this several times ( daughter never checks her pockets ) most times it travels on through in time, but a few times i needed to remove the front of the machine and pull the hoses off the pump and get the bugger out.
