Jacuzzi J270 error code F1 control panel unresponsive

[maxl49]

Hi,
Today my jacuzzi j270 control panel became unresponsive. no button is doing anything. Then after a few power off power on, it started displaying the F1 error code. I can't find any documentation on this code. Does anybody knows what it means?
Any help would be greatly appreciated.
Thanks

More information. According to the panel, F1 refers to the fuse on the board but it doesn't seem to have blown

More information in case it helps anyone experiencing this... It seems that F1 means the panel was in filter program selection (the programs are F1, F2, F3. Cycling through the programs I managed to get the heater and pumps working. Now it keeps going from the actual temp to displaying 106f as a temp. I'm assuming the panel is faulty.

Yeah, sounds like a sticky button.
