We have a Jacuzzi Echo Spa Z145 about 5 years old that sits on a wooden deck. Lately the pump and heater doesn't kick in until you jump on the deck. Sometimes it works correctly, kicks off and on when it should, stays up to temp, etc.. then it stops and won't start again until you jump on the deck. It sounds like a loose connection somewhere, but I can't find it. Any ideas? If something needs to be replaced, can you tell me where to purchase and appx how much?
Thanks, Kim!

I have no idea of the problem, but ****, that's funny!

Try unplugging and re-plugging in all the harnesses attached to the control box (temp sensors, if any, press/switch harness, if any, topside control harness, if any) Might just be a little corrosion, and a slight shake makes proper contact... just a guess.

But I have to say, A remote control spa is pretty cool...

Yeah...good thing we live in the country because if we had neighbors they would think we are crazy! We always try to remember to jump on the deck
when we pass the spa to keep it up to temp (think of the visual!).
I'll try your suggestion this weekend and let you know if it helps, thanks for the reply!
