If the topside is out you need to check if the plug from the topside came loose on the circuit board. I would unplug the topside check connections and reinsert plug then turn spa back on, if still no power to topside you need to check the transformer that is on circuit board. You should have 220 volts going into transformer and 12-24 volts coming out. This is what powers up the topside if transformer has proper voltage coming out the the topside is bad. You should have a 5 year warranty on that spa if you are the original owner.
