FL Error message H738

[lc209]

We just got a new to us Hydropool H738 7 person hot tub.  While most of the time it runs fantastic, we are getting the FL error message, which shuts off the jets, then resets itself after 5 minutes or so.  I've looked it up and this seems to be a pressure switch issue.  Is it easy/inexpensive to replace?  Is this something that can be done ourselves or do we need to hire a professional.  We have already put a ton of money into updating our deck, having an electrician hard wire, etc., and really don't have much left to spend!  Thanks for any advice!

Usually very easy - it is simply threaded into place, two wires which usually simple plug and unplug.

The one caveat is that it can dump water right into the control box, if that is where it is mounted, so be sure you drain the spa. If your tub has valves to isolate the heater, you can use those, but you may still have to open a union fitting nearby to let a small amount of water escape from the pipes in that area.

Where can I buy a pressure switch, and how do I know which one to buy (if there are many types)?  Thanks!

 You buy the one that looks just like yours    there are a few different ones out there so as long as the threads are the right size it should work, get metal threads not plastic if you have the choice.  Should run you around 40+ bucks?

 To buy you can go to most spa places and they should have one or google hot tub pressure switch prolly get a few hundred hits.
