![]() HOT The thermistor on the load box circuit board has detected a temperature of 180 degrees.įLO When blinking, heater is deactivated, pump is on and flow switch is open. Control panel and remote panel will automatically return to normal operation. Buttons have been pressed too often in short period of time. HOLD Control Panel and remote panel are temporarily deactivated. Press DISPLAY, MODE and (down) button within 3 seconds to unlock panel. LOC Hot tub control has been locked by pressing the DISPLAY, MODE and (up) button within 3 seconds. Check interlock jumper located in the sensor harness A Solid indicator means the function has been manually activated. A Flashing Indicator means the function has been automatically activated.Ģ. The jets and air indicators will display in one of two ways:ġ. Three seconds after the desired temperature is set, the display defaults back to show actual water temperature. While the actual water temperature is d isplayed, pressing (up) or (down) button within 3 seconds will cause the set temperature to increase or decrease by one degree for each press. Pressing either the (up) or (down) button once will display the set temperature. The default display show s the actual water temperature. More hot tub repair tutorials and videos are here.Troubleshooting Sundance 800 Sys tems using the Control Panel FLC goes away and you’re fine and running you know again it’s the pressure switch. You can simply just pull one of those leads off and it should go to FLO or it’ll just clear itself, right. There’s nothing flowing through this actual heater and it’s going FLC which means it’s closed. Make sure the pump is not running and there’s no movement in the tub. Now, if you have an FLC, which means it’s reading closed when it’s not running. Everything is running perfectly fine up ’till this switch.Ĭhanging it, I mean, I don’t think we need to go too far into it. You know that there is no malfunction within the board, end of the operation, or this cable. So, at this particular time I would know that everything is running and this pressure switch is faulty because it keeps going to FLO. Now, it’s going to send power to the heater to allow the tub to heat. We’re going to jumper across these two leads right there just to make electrical contact between the two of them, FLO’s gone. I mean, you could just bend a nail in half. I just took some green wire, stripped both sides. These pressure switches are non-adjustable. There’s got to be something wrong with this pressure switch”. So the water is running through this heater bearer and we still have FLO we’re going to say, “Hmm. Okay? So, if we have movement of water in the hot tub and pump one is running and the water is moving. ![]() One is pump one is actually running on low speed and two, that there’s movement of water within the hot tub. ![]() 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. 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. 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. ![]() Obviously, FLC., flow switch closed is the opposite. which means flow switch open because the contacts have not closed. If it does not close the contact you’re going to get an FLO. This switch has a diaphragm side of it which is going to go up, close the contact between these two points. The purpose of your pressure switch is to measure pressure in the line when your pump is running. We need to understand, right off the bat, a pressure switch has two error codes. A bit of a diagnostics that go into looking over the pressure switches themselves. Most part actually is qualify pressure switch to be changed. What we’re gonna do right now is change a pressure switch.
