Pump needs new Impeller?

[missguidedone]

I have above ground pool - Astral Pool pump - 1800 series, self priming and sand filter. The other day I went outside and the hose had fallen off the skimmer holder. The pump/filter was running and made a clicking noise that I had never heard before. The water had drained out almost to the bottom of the skimmer. I refilled the pool and since then the pressure going into the pool and sucking out of the pool is low. I cleaned the filters - cleaned the sand, it is ok. It still runs, but not like it should, I have bypassed the solar because of the low pressure. Could the impeller have broken when the water was low? The filter seems fine. The pump sounds fine and is running, it is somewhat hot to the touch.....but I dont know if it was always hot...it's not HOT HOT
Thanks from a mechanical genius....

I just opened my pool and turned on my filter.The fiter gauge is showing high pressure but there is no filtration going on.When I shut the filter the gauge is still showing high pressure.Do I need a whole new filter?I hope not it is only 1 year old.
