Pump still running but no longer moving water...

[mas985]

If there is no water movement at all and the filter pressure reads 0 PSI then it could be the impeller is either not moving or completely clogged or even the suction pipe is completly blocked. That would be consistent with the hot water as well. The only way to really check the impeller is to remove the motor from the wet end so you can make sure it is attached to the motor shaft and it is not clogged. Double check the suction lines for shut off valves or blockage. A broken check valve on the suction side can also block the line.

No water movement with very high filter pressure would indicate a return side blockage.
