Not draining

Sorry do not have the model number with me. I can look it up once I get home if needed. The thing is not draining all of the way. I have checked the hose and cleaned some gunk out of it. I ran the rinse cycle waited for it to start and then cancled it. I have water draining from the hose at a slow steady rate. It takes 4 times of running and cancleing before I can hear the pump run dry. The pumps runs about 60 seconds. Any guidance will be great. Thanks
