I have a Dream Maker Hot Tub, model X4H-UHS-DMI-GG-F, 120 volt. It heats up perfectly, lights and temperature work perfectly. But when I'm sitting in the hot tub and I press on the jets button, the jets won't turn on. The jets turn on by themselves of course to heat the hot tub, but if I want to turn them on manually using the button it just doesn't work. I opened the box where the control board is and checked all of the connections and they are super clean/perfect and tight. I do seem to have to press kinda hard to turn the temp up and down. Do you think I just need a new display or what do you suggest I try first to get the jets working? Thank you for any help!
