After refilling out spa pool it worked normally for 2 days, then the error 4 thermal trip message came up. We turned the power off and a few hours later, turned it back on. The LCD panel came up with priming but then went straight to the error 4 thermal trip message again. It has done this several times….please help

You’ll have to trace the wiring to make sure there’s not a wiring issue, and then investigate each step in the spa function to see where there may be a malfunction in the process and replace that component.
