There is only a few reasons a hot tub won't heat.
Thanks for the video - really helped me understand more about the system. I have the same exact model and my problem is (after removing the filter and installing a brand new heater) , the 240 volts would last for about 1-2 minutes and then goes back to 000 . Any thoughts would help . Thanks
The heater clicked off and you'll get 0. Only have the 240v on the heater element when it's heating.
@@VIPPoolsandSpas so it’s normal to shutoff off during the heating ? It goes on and off on and off . I’m by my hot tub now . Observing :)
@@elementrepair5084 only comes on when it calls for heat. When it comes up to your temp set point, it will shut off. If it's turning off and on at random, it might be the pressure switch. That's if you have one. A pressure switch turns the heater on or off. You would hear the relay clicking.
i replaced heat element, checked for air locks, i have voltage at the element. and if you shut valves on the union to heater, it gets hot.
At the filters their is no sucking . pressing jets 3 on immediately cuts the heating symbol off.
no error codes. any advice greatly appreciated
AC Volts on meter( set for at least 240 volts!).
Hello, Thank you for this video. We have the Gecko S Spa Metapack Series. The top display for turning on spa seems to be dead. No lights and not turning on etc. My husband is an electrician and he has tested and confirmed power to board but top display still nothing?? Any suggestions would be very appreciated.
How many pumps? Does the pumps come on at any point during the day?
@@VIPPoolsandSpas one pump, no does not come on at all. Keypad is now showing 3 red lights.
@@amyruppert1322 3 dots or 3 lines? Turn off power to the tub, unplug the topside from the spa pack and then turn power back on. Pump should come on. If not, test the fuse. Im assuming he already did that?
I have an older spa. I have 15 ohms and 110 volts on a 110 volt sys. It doesn't seem to be getting hot?
well water? When was the last time the element was changed? When you say old, how old? Is it air button to turn the pump on?
I grabbed myself, then grabbed a meter. I took the filter out, the flashing lights went away and the temp stopped flashing and let me set it like normal. I took a chance and touched the outside of the heater. Its lukewarm. Its getting 240. The pressure switch didn't click when I turned it half a turn.
I turned it nearly a complete turn, still no click. heater still barely lukewarm after about ten minutes. temp of water went from 92 to 93 degrees.
@@traumajock if your testing 240V at the element, no need to mess with the pressure switch. Its the pressure switch that turned on the element to get the 240V. Test element, if you get 240V again, turn pressure switch counter clockwise until the relay clicks. Power will be on, so watch your fingers. after you hear the click, turn switch back clockwise until you hear another click. You should again get 240V.
What about on a balboa heater, premium leisure pn741 hot tub with balboa pbp501x control, 4kw heater tests 14.3 ohms between posts. (Within spec range) Has 120v on each side of heater post to ground, but post to post only shows a couple volts. Amp draw less than 1 amp. No codes heat light on. Circuit board doesn’t have any visible defects front or back. Fuses test ok. No pressure switch it uses a and b temp sensors. Heats slightly but only at 87 degrees when set to 98 degrees. Verified temperature display is correct temperature of the water with a digital thermometer. Input voltages are all correct. Tried running with filter removed no difference.
Sounds like the circuit board
@@VIPPoolsandSpas found no output voltage on the pin from the left side relay on the control board, control board is unavailable. Is there a way to repair this without replacing the entire control system and topside panel?
@@nategrube352 see if you can find an electronics guy to test and or replace the relay.
240v Power to heater, won’t heat up, no codes. What should I check next?
Amps
I have a Superior Spa, San Juan, Gecko, 240v M-class (MC-MP-SBD spa panel) I'm getting a strong 240v from the heating element. The water is not heating up. I'm not getting any error codes. I've tried removing the filter, unsuccessful. I've replaced the temp probe, unsuccessful. Please help? any Advice? thank you
Did you try the high limit?
Sorry. Lol. It's your heater element. Disconnect the two leads from the heater element with the power off. Test the element without the leads for continuity.
Kendall, did you fix the hot tub and was it the heater element? Thanks
Can you change the relay if it doesn’t click
What relay you think isn't clicking?
Hi thanks for your videos! My spa was not heating properly. What I'm getting now is no error message, and I turn the heat setting up to say 100 the temp was around 80 as I turned the spa off for a few days. The pump works great I cleaned and replaced the filter the heater light goes on but goes off within a few seconds? Any help would be appreciated. Thanks Donnie spa builder Sc-CF-122-01
Whats turning off in a few seconds? Power, pump?
are you testing the element for volts and amps?

We have tested the white terminal and the red and white is testing 0, black and red is fine, and red and black is testing 120. But the hot tub pump kicks on and the top side control. What's missing?
Assuming your hot tub is a 240v hook up. White and Red should be 120v. White and black should be 120v. Red and black should be 240v. If your getting 120 on the red and black, it will be the wiring in the breaker box. Watch my other video on where the wires should go.
@@VIPPoolsandSpas it is a 120v. It just plugs into the wall
@@marinagardner342 a 120v only has a white, black and a ground
@VIPPoolsandSpas correct. When it goes into the circuit board, it has white, green, and black. It also has a red jumper wire.
@@marinagardner342 send a picture of that to info@vippools.ca
Anyone know anything about lower control unit pack on 2 pump s-class ?
I need help troubleshooting and of bad replacing it. Thx
What do you want to know?
@@VIPPoolsandSpas my brothers hot tub went out and I really want to help him get it together as he enjoys it after a long day at work. I want to replace it with him and get him the parts or part. Is there a site that sells used parts? Or does it have to have the exact gekko part or can another. 2 pump jet lower pack thingamajig’ work
On a budget
@@UnderdogSTL They don't make the s-class anymore and it would be better to just put a new spa pack in. Balboa VS501 or a Balboa BP. It depends on whats going on with what you have now with the gecko s-class.
I think he said it is a “lower control pack” ??
We both are low voltage communications workers and gonna try and get it going. I’m trying to surprise him and possibly get the part
I guess I really need full details.
He complained outside that a rodent chewed some wires and I said is it the pump he said no it’s the lower control pack
It turns on but don’t heat. The mouse chewed through the cable that runs from the heat pump to the lower control panel board and fried it. Curios on ballpark what parts were gonna cost if I help out
Hi hoping you read this…
What if it calls for heat with no error code and I still get 0 volts across the heater?
Checked house input get 240 coming to the board
Get 120v across each heater input tab to ground.
Checked fuses they are good.
Checked resistance across the heater got proper 16 ohms.
Could the pressure sensor fail while not reporting an error? I’ve screwed the adjustment in and out all the way and it never clicks into 240 across the heater. I’ve shorted directly across the pressure sensor tabs as well and still won’t go on. Disconnecting either if the wires on the sensor and the error code immediately goes on.
Everything appears to be working is it an internal circuit problem? There is no evidence of failure, no burning no discoloring nothing.
Any advice?
I’ll pray you have an answer I’d hate to face the possibility that the circuit board is broke and not fixable.
Change the heater element.
@@VIPPoolsandSpas I've read a diagnostic flow chart that reads if I am not getting 240V across the element when it is calling for heat the problem is in the circuit board, not the heater element. The same diagnostic reads that if I do get 240 and no heat, then the element is bad.
Since I am not getting 240, are you sure the element is the problem? I am hesitant because it is a $180 replacement and I'd hate to be back at square 1 $180 less. Unless I just get the element which looks to be about $40 I suppose....
I very much appreciate your help, if you insist I will order a new element.
Also, it appears that I may have damaged the high limit sensor last night, as now I am constantly getting the three dots. Is the high limit sensor simply a continuity switch that breaks the continuity above a certain temp? Meaning for diagnostics, could I just jump the connection pins to rule out this as a problem and replace the sensor later?
@@luckyleaf6 send a picture of the circuit board to info@vippools.ca
Additional fwiw. I was able to run the system error free (no blinking dots)
I disconnected the heating element from the terminals. Turned on and called for heat. Pump on heat indicator on. Checked voltages. Zero across the terminals. 120 across the left terminal to ground. Zero across the right terminal to ground.
Might have to test the relays for the heater element.
hot tub not heating
balboa legend series m7
no heat.
replaced heat element
filters are not sucking. and pump 3 switches off heat symbol.
..hot tub not heating.
250v at element.
pump is spinning and seems to be working .
any help, would make us best friends
Make sure the pump that pushes water thru the heat tube is working
@@VIPPoolsandSpas it is spinning but is it possible that its blocked and still spinning/working.?
thanks for your response
@@davidbrooke4829 did you pull the filters and see if it changes? Any error codes?
@@VIPPoolsandSpas pulled the filters nothing changes, doesn't seem to be pulling water in where filters house, there are no error codes, the symbol states its heating then changes after a while if you turn jet 3 on it immediately stops the heating symbol.
@@davidbrooke4829 if you hit the button for another pump, it will turn the heat off. Something may be restricting the flow.
hi.can you help me for my spa i have a spa s-class with 2 pump .pump no.1 is working,pump no.2 is not working,and i have 3 flash doc.and not heating,so i'm try to fix this,i check all 3 fuse is good ,i switch the connection from pump one to pump 2, i find out pump no.2 is working, so that mine 2 pump is working, so i change the relay on pump no.2. still the same pump no.2 not working can you tell me what's the problem?thank you.
What pump (1 or 2) pushes water thru the heater tube? (heater element)
@@VIPPoolsandSpas pump 2
@@tranquannien5596 Weird you have 3 flashing dots on pump 2. Normally pump 1 pushes water thru the heater tube and turns the pressure switch on or off (turn the flashing lights on or off). Doesn't your pump 2 push the water thru the heater tube?
@@VIPPoolsandSpas sorry i don't know nothing about spa,thank you tell me that,so what's the pump 2 doing? why don't turn on?
@@tranquannien5596 could be anything. was trying to figure out what pump is pushing water thru the heater tube. Test the fuses and test the pump capacitor.
Have a Coyote Hot tub. Replaced heater, have no codes, light on control panel shows heater on and yet after 24 hours only up to 92 degrees. Can you help?
Test element for volts and amps
Tested for 120 volts on each feed line and that is fine. Will have to get an amp meter.
I've got this issue. Same gecko pack
Hope this video helps you out.
@@VIPPoolsandSpas checked all three fuses. They were fine. But no continuity at the heater element or pressure switch..
@@gray5857 Test the volts anyway. If no volts, try changing out the heater element.
@@VIPPoolsandSpas pretty easy to get the element out?
@@gray5857 Most times. Just follow my videos.
Thanks for making this video.. I am trying to trouble shoot our hottub. I followed the steps in your video:
1. Take out filter (no change) - also I checked to make sure the valve inside the filter housing had not broken off(this was in another video of yours i think)
2. Power to board :120v, 120v, 240v
3. Power across heating element: 240v
4. Checked all three fuses for continuity (they all passed)
------------------------------------------------------------------------------------------------------------------- abnormal results----------------------------------------------------------------------------------------------------------------
5. Pressure Switch - When I turned the screw inside the pressure switch counter-clockwise (I tested up to two turns counter-clockwise actually) I did not hear the "click" you were talking about.
Does this mean the pressure switch is the problem?
Test the element for amps. Is there an error code on topside? If your getting 240v at the element, it's not the pressure switch. The pressure switch turns the relay on for the heater to heat. More interested if you have an error code.
Plus, need more info on what the tubs is doing and not doing. What's the issue?
@@VIPPoolsandSpas the hot tube won't heat up. I am getting three blinking lights error code on the top panel.
@@padr3ko circ pump working or pump one low speed? Pull filter? Would just change pressure switch if these other things are working fine. Adjusting the pressure switch is just to see if that's the issue.
Why my tub control temp goes up then turn off the pump but no heating at all
not sure. you have to try and test a few things to figure it out.
@@VIPPoolsandSpas if the heater clicks in that means that is working ok?
How long it takes to heat up?
@@dannydeleon7885 no. The click is the relay for the heater element
@@dannydeleon7885 did you test the element? If its working, should take about 6 to 8 hours to heat up to your set point.
Hi I need some help. I have the Gecko S class. Ive had issues for a while. I have replace the heating tube already. I do not have any codes. I have tested all fuses and power coming in. All seem to be ok. My first problem is that 1 it doesn't heat or heats really slowly. No error codes. Then all of a sudden it will heat up. which is great. But when it heats it gets to the set temp and then throws a error. High limit then of course i have to flip the breaker or it doesn't engage the heater. any ideas?
It finally heated then stopped. I was about to buy a new spa pack but then it started again. now im back at not heating.
Gee. thats a good one. Test the heater element volts, amps, etc. Heater relay is stuck open or closed...random I guess. I would say a few more things, but. you say its getting up to temp and an error comes on HL? High Limit error code right? Set temp to 100F, then when it hits the 100....also test the temp of the water. SO, FIRST....test the volts and stuff, SECOND. set temp to 100 and test the temp of the water. See what the temp difference is. See our video on testing volts and amps. Let me know after you do those tests.
@@VIPPoolsandSpas thanks for the quick reply. temp when set to 100 is accurate, tested that to be sure. Currently its in the not heating stage. last time it was doing so i tested on like you did on the video all fuses and lines coming in. i got readings like i should. when I tested on the heater itself there was nothing there ( thought i was doing something wrong) because i tried again the next day and there was voltage... and then it started heating. but back to the cycle of 3 dot error code when it heats to the desired temp. so basically my hot tub is always running :)
@@opiejr97 when you changed the Element, did you change the pressure switch? See video on adjusting the pressure switch. Test element and when you don't have volts....pull the filter and listen for the click of the heater relay. See if that works.
I think it's something from the filter to the spa pack/circ. Pump
@@VIPPoolsandSpas new heating element is one unit so it came with new pressure switch etc.
so I had a FLO CODE & BYPASSED THE SENSOR & CODE DISAPPEARED & HEAT LIGHT WENT ON. sO I CHANGED & PUT IN A NEW SENSOR & FLO CODE DISAPPEARED & HERE A CLICK & RED HEAT LIGHT COMES ON. THE LOW & HIGH PUMP ALWAYS WORKED FINE & STILL DOES. & THE FUSES ARE GOOD. THE HEAT ON THE OTHER HAND IS ONLY UP TO 72 F. & THE WATER IS COOL. WHEN I TEST THE ELEMENT I DON'T GET A READING OF 120 AT ALL. I GET NOTHING . SO I GUESS ITS THE ELEMENT OR DO I NEED TO CHECK OR CHANGE ANYTHING ELSE. EVERYTHING SEAMS TO BE WORKING FINE....
if you have the Gecko spa pack the pressure switch turns on the element. Make sure the pressure switch is working (any error codes?) If theres no codes or issues, its the element.
@@VIPPoolsandSpas I HAVE A Z135 JACUZZI - OLD UNIT BUT NO MAJOR ISSUES TILL NOW...PRESSURE SWITCH IS WORING IT TURNED OFF THE FLO CODE & THE RED HEAT LIGHT GOES ON WHEN SENT TO TEMP ON LOW - EVERYTHING SEAMS TO BE WORKING INCLUDING THE PUMP THIS AM WAS ON 72F BUT WHEN I TOUCHED HE WATER IT WAS COOL
SO I GUESS I WILL HAVE TO GET A NEW ELEMENT- IF I AM NOT GETTING A READING 120 EITHER IS THAT MEAN THE ELEMENT IS BACK - I GET NOTHING...NO ELECTRIC
THE ELEMENT IS BAD- IM NOT GETTING ANY READING TOP OR BOTTOM OF SCREWS
@@VIPPoolsandSpas WHEN I PUT METER IN WHITE & black i get 120 when i put on 2 terminals i get continuity light goes on ??? no 120 or 240
change element.
