We've had to change the leak detector in our 5610's a couple of times. One machine in particular is on its third one. This machine is less than 4 years old.
But, If your fluid is overflowing, that would tell me it is overfilled. Toro has specific instructions when filling the fluid after changing a leak detector. I can't remember what exactly it is, but your service rep should know. But if you haven't changed it in two years...that shouldn't be the cause.
