If your spa or hot tub has been working fine, you just drained and refilled it only to find out that the jets or heater won't work, or you're getting some strange reading on your display.
This forum is reserved for those with circulation pump problems. This kind of pump is generally used to circulate water for heating and filtration purposes only.
These are generally the larger pumps that force water out of jets. If you've got a smaller circulation or air pump problem, see the Circulation Pumps Forum.
