Matt-
The pump impeller or shart seal might be "frozen".
Usually there is an exposed shaft coupler between the motor & the
pump; if there is is you can grip it with a pair of channel loc pliers
or vise-grips. Grip the coupler & give the shaft as much turn as you
can in both directions.
The shaft should turn freely, if it does not (at first) then the pump
was the problem.
If it was free then the motor is the problem.
Give it a try & see if this fixes the problem.
In the old days pumps & motors were rebuilt but now they're usually
replaced but they can still be repaired.
If you live in or near a reasonably sized metro area there will be a
motor repair shop.
You can wire in a timer is series with your current switch
Timer (clock) turns power to switch on & off; having the swith in the
circuit as well allows you manually control pump as well.
Intermatic is one of the major control mfrs

here is my best guess of the unit you need
http://www.intermatic.com/?action=prod&pid=8818
but checkout the specs, it will control a single 220v load (just the
pump)
if you have a heater to control as well you'll need a two cirucit timer

(no I do not work for Intermatic but have used their timers for years)
