Thank you for posting your question here on Fixya.com.
Your pump seal is the most likely culprit. As the water leaks around the motor shaft it will trickle down to the bottom and drip off. Double check your drain plugs first to be sure it isn't one of them dripping. Assuming they are not, it is the seal.
Waterway pumps use a press-fit 1000 seal. It is not an 'easy' seal change compared to most. You may want to take it to a pump repair shop for the seal change and the shop warranty that should come with it in case it is not done perfectly. If you do it yourself, get a piece of 1" rigid PVC about 8" long with clean-cut squared off ends to use as a driver.
Remove the front pump cover exposing the impeller. Remove the cover plate off the back off the motor to expose the end of the shaft opposite the impeller. Depending on the motor, lock the shaft with a wrench, screwdriver or allen key then spin the impeller off counter-clockwise to expose both halves of the seal.
Remove the old pieces completely and replace them. Put a SMALL bead of silicone caulk along the beveled edge in the seal plate, line up the metal cup making sure you NEVER touch either seal face in the process, and then punch it down with a mallet and the PVC pipe. The ceramic piece can get a small amount of a synthetic lube or just use a little soapy water to ease pressing it into the impeller recess again making sure not to touch the polished seal face. Use clean rags or pieces of paper to cover the seal as you work with it.
