This is such a great machine that has worked in the past but it seems to have from time to time issues with the middle sprayer not spraying. There are 3 sprayers(bottom, middle and top). It has been taken apart and washed out so sprayers aren't blocked they are clear. The shaft that the sprayer goes into is clear as well. I even washed out the water delivery system and it completely clean. A few times we have caught the middle arm spraying but there has been few washes the sprayer hasn't moved from the original position. Everything seems to be in good working order. What can I do to check or trouble shoot further? There is water coming out of all sprayers so the water is being transferred and when I hooked the sprayer to the water hose it spun so it seems to be an inefficient water flow of some sort. Is this a pump issue? The sprayer is also clear form anything hitting it and we also make sure there is clearance with the sprayer to make sure nothing hits it.
