WatkinsPressure Switch: Electronic 2-Wire 3-Pin Caldera

The spa heater was not turning on and the console showed an error, that turned out to be caused by the flow sensor being bad. After watching a YouTube video on how to replace it, I put the new flow sensor in and the spa runs great now. Very easy.

I saw other reviews that said this fixed their problem so took a shot and it worked for our Rythum Hot Spot hot tub by Hot springs! Everything worked except it wasn't heating. It brought an error code of two lines of dashes ------- and the ready and power words were flashing. We tried all kinds of other methods first, and even the the ohm reader said our current switch was working we decided to replace it and it worked!!! Probably saved hundreds $$ without paying for a service call and their parts!

I was changing out the heater on my Hotspot spa and accidentally broke off the Watkins pressure switch. My bad. Luckily this individual little part is available to buy. It's perfect, OEM, easy to install. Very happy with it.

Got rid of the dashed lines on the screen

My hot tub stopped heating properly, did some research and found that replacing this part would solve my problem, and it did.Installation is reasonably easy for anybody somewhat handy and not afraid to get a bit wet. Take off some covers, unscrew the old sensor, and quickly screw in the new one. Water will shoot at you, unless the hot tub was drained first. Connect the new sensor plug, where the old one went and done.

Product worked as it should, fixed the hot tub no issues.

I was able to install without issue and it actually fixed my caldera spa with flow issue dashes on

I got my hot tub running again thanks to this. The wife keeps wanting to buy a new one and I keep fixing the old one. Much cheaper.
