20 Most Recent Jacuzzi Balboa R574 System for 1 2 Speed Pump Value 52221 05 Questions & Answers

Need to know what buttons your topside control has... depending on the model, some have a mode button which you press and release and then immediately press the temp up or down, to select SL for sleep (no heat), ST for standard (heat as needed) or EC for Economy (only heat during filtration). If the mode button is not present, and you have a single temp button and light button, try pressing and releasing temp and then immediately pressing light button, repeat until choice appears, then wait, it will hold last displayed mode.

If the system is the Jacuzzi 52221-05 system mentioned in the subject header, there could be a stuck relay causing the problem and you might need to get a spa technician out to assist you in repairing the problem. However...

If it is a Great Lakes system as mentioned in your message body, then there could be a programming issue allowing the filter cycle to run continuously. Provide a model number off of the Balboa control. Then we can provide you an instruction manual or reference card to assist you in resolving this problem. you can also search our online manuals at our website. You can find them online at:

Either the spa is incorrectly wired or one of the fuses is blown in the spa pack. Typically this is due to your electrician wiring the spa incorrectly and blowing the fuse on accident.

Ecn or Ec Message
Ecn or Ec Message

If the Ecn or Ec Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Economy Heating Mode.

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

Ecn or Ec is Alternating with Temp:
The Spa is Operating in the "Economy" (Ecn or Ec) Heating Mode.

The Water Temperature is Sampled Only during Programmed Filter Cycles. The Heater will Only operate and Heat up to Set Temperature during the Filter Cycles. The Water Temperature will probably drop Below Set Temperature between Filter Cycles. Other Heating Modes are Standard, Standard in Economy, and Sleep Modes.

Ecn or Ec is ON Solid (Not Flashing):
The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode.

Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not Current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.

Located behind the access panel there is a grey box that is the spa pack. Open that up with the 2 screws on the top of the pack. There is a small glass fuse on the circuit board. One of those fuses is most likely blown. If that is not the culprit you need a new topside control. More than likely it's the fuse.

If the pressure switch is jumped properly and you still are not getting a call for heat, then you are having a problem with the circuit board and it most likely is going to need to be replaced.

If the heat light is coming on but no voltage is going to the heater, this would also indicate a bad board.

You can find the 52213 circuit board online at: http://balboadirect.com/52213.aspx.

Hope that helps.

This is likely an issue with the GFCI breaker not being ableto handle the load or a problem with the high speed of the pump. You can find answers to common spa orbath problems online at http://www.balboadirect.com/support.aspx Hope that helps!

I will advice you get a technician to come to your house and take a look at it, since you are sure of the position or status of the Balboa jacuzzi, it will be better you get someone, a professional to help take a look at it, this is not (DIY) do it yourself as you can see.

This is probally a bad motor, the sound you hear is the motor trying to start but when it can't the breaker trips. If it takes a start capacitor it may be this rather than a motor but you will have to pull the motor to see. It may also be a clog in the pump but the motor sounds like the problem.
