Softub 220 - no power after installing capacitors to stop motor cycling

[Rodent]

Hi, my Softub was recently cycling the pump on and off continuously. I read on this forum that installing a 10uf capacitor to each of the temperature sensors would stop the cycling, so I opened the circuit board box and installed 2 x 10uf capacitors as described. I’ve put the unit back together and now there is absolutely no power whatsover. The pump doesn’t run, the light doesn’t come on and there is no sign of power on the control unit. I checked the supply and the fuse and it’s all ok there. Please can anyone advise what might be going on?
Thanks
