I own a Balboa Stealth spa. It was in my house when I purchased it. I believe it is circa 1996. I have replaced the pressure switch and temperature sensors. My tub will not heat up past 65 F. It seems to run on low speed only. I can not find any operations manual online. Is it stuck in 24 hr. filter cycle? It is not indicating any trouble code on the top side panel. I need to get a hold of a manual to troubleshoot this.

yes it is possible

Solid or flashing "Fl"?

Flashing - clean filter, most common problem
Solid - Replace the flow sensor/pressure switch

Jump it, (bypass it with other wire.) If the heat kicks on, the psi switch was bad.
In the event that works, replace the switch, do not leave it "jumped" or further damage will occur.

I have a Clearwater Spa with a LM8000 spa pack that the control module does not work. Can I purchase just the control module or do I have to replace the complete system? If I need to replace the complete system what system can I replace it with?

Flow issues can be frustrating, check each of the following
1. Low GPM.
2. Low Water Level.
3. Blocked Suction Fitting.
4. Blocked Skimmer.
5. Dirty Filter. (Try run system w/o Filter)
6. Too Many Closed Jets.
7. Closed Slice Valve.
8. Heat Related Pump Not Running.
9. Heat Related Pump Not Primed.
10. Malfunctioning Impeller.
11. Incorrect Heat Related Pump.
12. Circ System Misconfigured.
13. Sensor Malfunction.
If none of those help try this. There is a link to s Balboa site for service tech diagnostic help. There are step by step instructions for diagnostics.

First and foremost, there really is no such thing as a Value 3 System by Balboa. Balboa has a large line of systems with various names such as Value Pack Retrofit kits, VS, ES, GS, and our new LM8000 systems. If you can locate your product part number on your system, you can visit the Balboa Direct website manual downloaded section at: BALBOA DIRECT MANUALS and download the latest manual for your product.

Hope that helps.

SLP or SL Message

If the SLP or SL Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Sleep Heating Mode.

If the SLP or SL Message is ON Solid (Not Flashing) on the Display, the Spa is Operating in the Sleep Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles.

You can find answers to common spa panel messages on the following page:

COMMON SPA PANEL MESSAGES

You can test the pressure switch using a multimeter. When the system is running (pumping water) the pressure switch should have voltage at both terminals, if the pump is on and there is only voltage on 1 terminal, you need a new pressure switch.

F6 typically doesnt indicate an error. This is usually a programming code that tells you spa to filter every 12 hours.

If it is a FLo code that just looks like an F6, then you need to either replace the filter, replace the flow switch , or make sure the pump is pushing enough water.

If the SnS or Sn Message is Alternating with the Water Temperature on the Display, it is a Possible Sensors Out of Sync Message.
If the SnS or Sn Message is Blinking or Flashing OFF and ON without showing Water Temperature, it is a Verified Sensors Out of Sync Message.
