Dave, surprising that yours lasted this long. In 2014, the OEM pumps were going bad in the first six months. Your pump is located to the right of the generator. It pops out of the washer bottle. Take it to any auto parts store, it's a standard pump. I think they're about $10.00.
I looked, but didn't see it.…..there's a post on replacing the pump and adding a one way valve. One of the issues with the 14's is that the fluid would drain back out of the wiper hoses and into the reservoir between uses. By adding the one way valve, the water stays in the plumbing and comes on instantly.
I had this pump number saved, I think it's a generic number - Windshield Washer motor 0-607
