We are having problems with our washer filling, especially on the rinse cycle, but we've also noticed it on the initial fill cycle as well. If we have it set on warm rinse, it will start to fill, then suddenly the flow is reduced to a trickle of hot water. After a short time it goes back to a regular flow, but then cycles to a trickle. It keeps this up until the washer is filled. I checked the screens on the hoses and they're clean. Any suggestions? Thanks.
