Hey. What we’re gonna do right now is change a pressure switch. Most part actually is qualify pressure switch to be changed. A bit of a diagnostics that go into looking over the pressure switches themselves. This here is a pressure switch. We need to understand, right off the bat, a pressure switch has two error codes. They’ll come off your top side display. One error code is FLO. The other one is FLC. Flow switch open, flow switch closed. The purpose of your pressure switch is to measure pressure in the line when your pump is running. So your pump comes on low speed. This switch has a diaphragm side of it which is going to go up, close the contact between these two points.

If it does not close the contact you’re going to get an FLO. which means flow switch open because the contacts have not closed. Obviously, FLC., flow switch closed is the opposite. If the pump is not running but the diaphragm is closing the contact you’re going to get FLC because it’s closed when it’s not supposed to be.

So, what I have here is we’ve got a pack with some power hooked to it and we’ve got out cable, which is your pressure switch cable, right up to the pressure switch on this heater, and we’ve got FLO. FLO is coming on the top side. First thing you’re going to do when go to someones house and they call when they have a problem with FLO error is taking a look in the tub and we’re going to make sure of two things. One is pump one is actually running on low speed and two, that there’s movement of water within the hot tub.

Okay? So, if we have movement of water in the hot tub and pump one is running and the water is moving. So the water is running through this heater bearer and we still have FLO we’re going to say, “Hmm. There’s got to be something wrong with this pressure switch”. These pressure switches are non-adjustable. What you’re going to need is a jumper. Here’s our jumper. I just took some green wire, stripped both sides. I mean, you could just bend a nail in half. It really doesn’t matter. We’re going to jumper across these two leads right there just to make electrical contact between the two of them, FLO’s gone. Now, it’s going to send power to the heater to allow the tub to heat. Pull that off. Back to FLO. Connect across. FLO’s gone and it’s running.

So, at this particular time I would know that everything is running and this pressure switch is faulty because it keeps going to FLO. I can jumper and make it work. That’s a lot right here. And the FLO goes away. You know that there is no malfunction within the board, end of the operation, or this cable. Everything is running perfectly fine up ’till this switch.

Changing it, I mean, I don’t think we need to go too far into it. It’s threaded fitting. Thread it out. Take a new one. Thread it in. Plug in your contacts. You’re good to go. Now, if you have an FLC, which means it’s reading closed when it’s not running. So, you’re going to go again. Qualify. Make sure the pump is not running and there’s no movement in the tub. There’s nothing flowing through this actual heater and it’s going FLC which means it’s closed. You can simply just pull one of those leads off and it should go to FLO or it’ll just clear itself, right. So, you pull one of the leads off. FLC goes away and you’re fine and running you know again it’s the pressure switch.

Address listed on this manual for any damaged or missing parts at the time of. Balboa Common Spa Topside Panel Messages. Here are the common spa topside panel messages that you will encounter with your spa panel. The spa topside panel messages include common diagnostic messages, operational messages, and various other messages such as reminders.

A hot tub control panel acts as a timer, keeps the temperature constant, turns off the spa if you forget to, and helps troubleshoot problems with your spa. This is why it is important to keep the control panel in good working order.

Dead Control Panel

If part of the control panel is dead or the whole panel is frozen, you will want to see if the problem is the circuit board or the control panel. Examine the panel to see if any moisture is inside the display. See if the panel or any buttons are cracked or if it could have possibly gotten wet. If only part of the control panel is not working, check for any blinking lights or error messages.

The first step is to simply reset the breaker. If there is still a problem, turn off the breaker again, disconnect the control panel, and examine the circuit board. Now turn the power back on and see if the hot tub starts to filter or heat up. The only sure way to test the control panel is to get one you know is working and connect it to the circuit board.

Circuit Board

If you have tested the control panel and it does not work with one you know is good, you will probably need to replace the circuit board. Some symptoms of a circuit board problem are a blank or partially blank display, slowness in displaying messages, or LED lights that are not working properly. If you test the board and see it has low voltage, that is another sign you may need to replace the circuit board.

Displaying Dashes

If the control panel is not displaying an error message but only dashes, you need to reset it. Turn off the power for about an hour and then restore the power to the unit. This should reset the control panel.

Strange Messages

If the display is showing strange messages or blinking several lights at once, there may be a software problem or a problem with the circuit board. Locate the circuit board connect and see if any corrosion needs to be cleaned. If there is any condensation, dry it out.

Blinking Red Light

A blinking red light on the control panel may indicate it needs to be reset. For most models you will turn off the power to the spa for a minute or two and then turn it back on. Turn on the lower amp breaker first if you have a hot tub powered by 240 volts. If it is 120 volts of household power, simply unplug it and then plug it back in after a couple of minutes.

Blinking Red and Green Lights

If both red and green lights are blinking, this could indicate low water flow. Resetting the spa by turning off the power, waiting and turning it back on is likely to resolve the issue.

If these troubleshooting tips don’t solve your problem, consult the owner’s manual for your controller. You can also contact the manufacturer for technical help.
