I would say that when this happened you were in the "filter" position. Sounds like your filter is working. Lay off the DE and run the filter. Your psi should slowly rise if your filtering properly.

I would bet the ranch that when that happened, you were in the "waste" position. It shouldn't have took more than a minute of two to regain a good flow and lower psi if that was the "backwash" position.
