No heat...

[tlynch]

Hi All,

OK so I had a SN3 error. So I replaced the Sensor assembly.

When I powere the spa back up it worked great, once. It came up to temperature. But now the heater will not come on again.

This is a Dimension One hot tub w/ ozone.

You may want to remove your filter and put it in a heat call and see if the heater will come on. If your spa has a 24 hour circulation pump, you also need to verify that is operating.
