Does the pump get power?
You should check the pump with a volt meter, could be a bad timer, or could have bad pump windings, the volt check would be the fastest way to determine
no i didnt when it kicks in it sound like its almost straining to start the pump and just dies out
there is an overload on the pump, if it's clear and engaging like that you have a bad winding in the pump motor and need to replace the pump motor
It will probably buzz again if you let it cool 15 mins or so and it's still getting power (spin cycle doesn't last that long though)(
i figured as much :(
Sorry for the bad news at least your not paying a 90.00 service call for the information :)
Almost pays for the pump
