No on the floodsafe hoses, just plain stainless. I let it sit for a day and then it started filling ok. This has happened before after I take off the inlet hoses. It seems to work itself out after a little while.
The DE was a drain issue, the drain hose had some restriction and I found a bobbie pin lodged in one of the outlet tubes from the pump. I fixed those issues then had the issue with filling.
