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.

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.

I have not. Could not find a telephone number for them. Do you have it? Thank you.
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!

Ok, with my limited knowledge I did a little troubleshooting this morning. The pressure switch on the heater does have a little leak and only closes if I turn the power off. It stays open if the power is on regardless of the pumps running or not. Don’t know if that’s normal. I attached pics of the control panel and the circuit board/wiring diagram as requested. The digital camera wouldn’t capture a good pic of the control panel but it’s displaying ======= steady and flashing ready. Any suggestions? Thanks again.

I thought you were asking about a HotSpot FPH Heat Recovery system and not a HotSpot spa.
Let's see what @RDspaguy suggests.

The problem you describe with the pressure switch can cause this error, as can faulty sensors or transformer.
Unplug the pressure switch from the board and turn on power. It should begin automated function (turn on pump) before throwing an error, possibly the same one. If it throws the same error before turning on the pump you have other problems too.

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 clear)?

I’ll check the ohms across the heater tomorrow cuz it’s raining now. Thanks for the guidance.
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.
