machine stopped at rinse cycle. shut off.

removed 5 screws from back of control panel holding back panel cover. removed control knob from front of control panel. removed screw holding Timer. slid Timer module to right and pulled Timer out. disconnected plug from old module. plugged
new module in and reversed previous removal procedure. Unfortunately this did not correct the problem as machine still stops at rinse cycle and shuts down. misdiagnosis on my part. called repairman and he diagnosed a bad control board.
Cost is 3 times cost of Timer alone.
