My Hot Spot Relay is showing ==== and the ready light flashing when the pump is running. The heater isn’t coming on either. Any troubleshooting suggestions? Thanks in advance.
I have not. Could not find a telephone number for them. Do you have it? Thank you.Welcome to TFP.
Have you called HotSpotEnergy?
I removed the filter and I have very good flow both with and without the filter installed. I will post the pics you requested when I get home. Thanks!Remove filter(s). Do you have good flow from the heat return?
If it continues, post pics of equipment area, circuit board, and wiring diagram on the inside control box cover.

No problem. Guess I won’t call them.I thought you were asking about a HotSpot FPH Heat Recovery system and not a HotSpot spa.
Let's see what @RDspaguy suggests.
I posted the pics and some more info in the Thread.Remove filter(s). Do you have good flow from the heat return?

Closes on no-flow ...
If describing a mechanical position sounds ok, electrical sounds backwards?
With power and gfi breakers off an ohms check at the heater terminals might be telling. That said, the leak suggests a new heater assembly is needed. Can you post a pic of the leak (annotate with an arrow if not cleaWhen the sub panel breaker on The ohms meter reads
Clarification: With the sub panel breaker on (power supplied to spa) the ohms meter reads OL (switch open) regardless of pump running or not. The leak is not in the heater itself but between the plastic “sandwich“ panels of the pressure switch. In the pic you can see the mineral deposits from the leak and it is wet. I ordered another switch to see if changing it fixes the problem.Closes on no-flow ...

I’ll check the ohms across the heater tomorrow cuz it’s raining now. Thanks for the guidance.Closes on no-flow ...

That's pressure switch?This is a common problem for a pressure switch, and the reason so many don't use them anymore. There is a thin rubber diaphram that actuates an electrical switch, and when it gets brittle and cracks it leaks water onto the electrical parts and shorts them out. I'm not familiar enough with this system to know what errors it throws when, but a leaking pressure switch should throw one or more on everything that uses one or it's useless. Get a pressure switch. Worry about anything else if it comes up.
That's a sensor. The pressure switch is the square thing next to it, and it's leaking at the edge of the housing, right were this style switch leaks when the diaphram is ruptured. Under it is a threaded nipple that screws into the heater.That's pressure switch?
Looks more like a suppository...

Changed out the pressure switch today and the spa is now functioning normally. $60 part from Amazon. Thanks again for your help and advice. You saved me a bunch of money.That's a sensor.
