Lambo

I believe it's a 2014 Relay. So my teenage son and his friends got in the tub the other night and started pushing buttons. Now the only thing on display is 2 rows of 4 dashes and dots. And appears not to be heating. I can get jets to run and lights to come on. Also it appears to run all day. Until I cycle the jets to off and then later starts running on low again. If I hit temp up , it shows 104f, but then goes away and reads 97f. Help pls
