Water not Heating

[bmccleskey]

We have a jacuzzi J365 hot tub. We emptied the hot tub and drained the pipes in Jan. because the water was getting cold. The ground wire came loose from the heater. Last week we reattached the ground water and refilled the hot tub. In 3 days it went from 65 degrees to 86 degrees. It hasn't gotten any hotter. Any suggestions would be helpful.

The spa should have heated up to temperature in 2 days. You need to verify that the heat indicator on your top side panel comes on when you put it in a heat call. If not, try removing your filter and then put it in a heat call. If the spa has a 24 hour circulation pump, you need to verify that is operating.
