I have a chinese hot tub with GD7005 running system,had a overheat on big box pcb board so had it fixed and tested by electronics engineer and put back on,all wires stayed in the correct positions and I rewired in,turned on the main switch 32amp in hot tub housing and pump1 comes on and stays on,then if I turn on the control panel each stage has jumped a cycle except the led lights I'm confused
