New to this forum. I have a 2013 Hot Spring Limelight series hot tub which I have had zero issues with until recently. I noticed the display letters/numbers started flickering and going off and on intermittently. Luckily, I was able to turn off the pumps and lights before the control head totally died! I removed the panel from the tub body and disassembled it, only to find that the silicon pad (3 buttons) on the left side which controls the jets and "mode up" and "mode down" settings was cracked around the base, allowing water to penetrate into the head and drip right onto the circuit board.
