Washer won't drain

Have a Maytag washer-model SAV5710AWW.It will go through the wash cycle,but when it gets to the rinse and spin,it won’t start the cycle.Thought it might be the control assembly.Any thought’s would greatly be aprreciated.If the control assembly needs to be replaced,would this be an easy switch ? or should I get a repair person out to do the job. Thanks,
