Thank you for your help after testing OHM at 0 and having no continuity I drained the tub put in another element and heated right up. Cant believe a brand new element was bade

[@VIPPoolsandSpas]

Could have been an air pocket that went past the first element and blew it. It happens.

[@BirdStreetVendors]

I appreciate your videos. Where I live most of the spa guys have retired or moved away . Seems young people don't want to learn a trade nowadays so no one replaces them. The remaining spa repair places said they would only work on spas they sold.One was nice enough to hear my plea and suggest some things. My daughter asked if my granddaughters could use our spa. she promised shed keep an eye on them to keep them from dong things. Then she got a call from a potential boyfriend and left them to it. They put a bath bomb on and then took turns turning the spa on and off a lot to bug each other. So then next time I go out there its full of slimy stuff. It turned on and off over and over.Like maybe the switch from them pushing it on and off so much. I cleaned to out and drained it and rinsed it . I flushed it the best I could. I replaced the control pad up top. Worked great for 2 months then the board fried where the power wires attach to it.I am a electronic/electrical tech for automobiles. But not spas. Im gonna buy a new Balboa board but Im afraid of why it heated the wires up so much. This a 110 spa. It has a breaker at the plug.It didn't pop that or the house panel breaker. Boards aint cheap so I was wondering if you could give me some advice on this. The board has a supersede number and the new ones are available. I can do the testing easily that you suggested. Im gonna look into the heater element to see if its coated when I pull it to swap the board. I think I'm gonna try to flush the pump out too, while Im at it, just to see if its still sludge in there. when I found it dead the water was still pretty hot so Im betting the heater is still good. Any other ideas I should look for?

[@VIPPoolsandSpas]

Most likely it burnt out because of the filter getting clogged and was putting a strain on the pump. Not much I can suggest. Maybe change the gfci on the cord after a few years and cleaning the filter more often. Flushing it out once is all you need.

[@geraldmerrill1940]

Great video. Easy to understand. I have a small hot tub with 4kw heater element and was experiencing intermittent breaker tripping. Did find a small leak in the Ozonator and replaced that unit. Still get a tripped breaker intermittently, might run for several days or weeks. Tested as the video shows, 240 volts were in from the breaker, and 120 V was on each side. Volts at the heater element were 236, not 240. Ohms at heater 14.9, Amps 16.5 on one side 16.2 on the other side (clamp meter) Continuity tested good. Any suggestions as to what could cause intermittent breaker tripping?

[@VIPPoolsandSpas]

When a hot tub trips at random it's hard to pin point the problem. How long has the tub run before it trips. And what's the fastest it has tripped after you reset it?

[@geraldmerrill1940]

@@VIPPoolsandSpas On June 15 replaced the Ozonator refilled and restarted. Tripped out June 23, again on July 7, I didn't reset until July 30 it tripped out on Aug 5, reset on Aug 13, and tripped out on Aug 20. I am in a rural area and we do get brownouts and sometimes full loss of power we have generator backup and I have noticed that when power goes out and the generator kicks in the hot tub trips out. I have a wifi temp sensor so I can see when temp drops off.

[@steveclarke4756]

Really appreciate this video! I'm wondering if there is any reason why you would have to change the heater tube as well as the element? I tested volts and amps on my 5.5kw element, both were 0 so I'm planning to change out just the element. Wondering when I'd need to consider changing the heater tube as well. Thanks!

[@VIPPoolsandSpas]

The only time you change the heat tube is when the ends get corroded. Whenever there's leaks coming from the end gaskets or even the element, there's a chance that it crowds the tube and creates little tiny holes.

[@steveclarke4756]

A quick follow-up - I first noticed this issue with the heat after a brief power outage. I can see there's a fuse on the heater itself. Is it possible that a blown fuse would cause this problem?

[@VIPPoolsandSpas]

@@steveclarke4756 When you say on it, you mean there's a fuse just above the heat tube on a little circuit board? If so, that is for pump 2.

[@steveclarke4756]

Hi again. I replaced the element but it seems that isn't the problem. I tried testing the voltage to the heater but I'm not getting any. I noticed a comment above mentioning a bad relay might be the problem. Is that the piece on the pack that has the two leads going to the heater?

Thanks for your great videos! We have an old spa with a gecko pack we test for continuity and meter beeps but when we test it live we don’t have any volts reading on the element probes. What to do next? We have a 3 dot code (flow) we have changed the flow pressure switch, the temp sensor in the tub, replaced the filter, purge for air. Pump doesn’t turn on when we flip the breaker but when it suppose to filter it runs for about 10 seconds and stops. Any other things to check for?

Hello - I have a Hot Tub that when the heater kicks in a clicks it blows the GFI breaker, could that be the elemenrt or anyway that I can track that down ? Thanks Jim

[@VIPPoolsandSpas]

Do the steps in my videos to see if it's the element or not. Disconnect the element of you think that's what it is.

Hi Jim great video .. Question I have is the tub is running and jets and pumps and filtration cycle also turns on. When I turn up the temp does not turn on heat ! Could be anything else . Could dirty filter ?

Hi. No Jim here. lol Test the heater element if there's no code and no heat.

your first meter was a clamp meter. Is there a reason you are recommending an inline Amp test vs. a clamp meter test.

[@VIPPoolsandSpas]

yep. easier to understand and easier to test with.

Hello! Your videos are Great! I have a balboa 2007 spa that I can’t get anyone out to look at. It is running but not heating. So I changed the heating element and sensors.

Does the tub have a cord with a GFCI on the end of it? Whats the volts coming into the tub? If you have 120volts and no or low amps, that sounds like a element issue.

Well I have small tub that is not heating up. I have replaced the heater relay and it is now cycling on when powered on. It has power to the heater circuit plug on the board, when the heater is not plugged in and it loses voltage when the heater is plug into the board. It is a 4kw element and has good continuity and has ohmed out good. I have yet to check the amps to it. And i cant figure out what is going on. Any thing will help.

[@VIPPoolsandSpas]

There's a few things missing here. Let's start over. What was wrong before you replaced the heater relay and what man you think to replace that?

[@ryanshannon5140]

I didn't have any voltage coming out of the relay to the heater. I did also do a quick test and jump the power pin on the back of the board and the heater did fire up and start to warm up. I noticed a low voltage to the signal side of the relay and power in just nothing out. This is what I am seeing now kzbin.info/www/bejne/ZmG7ZH6Ir9KaabMsi=hKZs7xU0BwI8c5pV

[@ryanshannon5140]

​@@VIPPoolsandSpas I initially purchased the tub without the heater working and checked the continuity and ohmed out the coil and found everything to be good. I then checked voltage and only saw 30v instead of 110. Common to ground was 30v, line1 to gound was 0. Line 1 to common was 30v. I probed the back of the circuit board and jumped the line(hot) side of the heater relay to the heater circuit pin and was able to get the heater to fire up. I swapped the relay with the exact same one and can get voltage out of the relay on the heater plug if the heater is not plugged into the board. kzbin.info/www/bejne/ZmG7ZH6Ir9KaabMsi=hKZs7xU0BwI8c5pV

I did everything you did basically I’m not getting 240 between the two heating elements so when I undo the plug from the circuit board, I’m not getting 240 from there. I’m only getting 120 from one side from the other side so basically the heat is only getting 120. Does that mean the boards bad or is there something that could be changed?

My hot tub is doing the same thing. I had to disconnect from heater to test or the breaker would trip. The one leg is getting 120VAC and the other leg is getting around 25VAC. Pretty sure a relay is bad on the board for the 25VAC leg. Was this what you’ve found as well?

Hi, changed my Balboa gl2000 3kw heater element as it wasn't heating with a universal Chinese element, it worked for 2 weeks but blew the fuse. I changed the fuse but still won't heat, circ pump wasn't working properly so I cleaned out all the debris but still doesn't heat. Ohm's and continuity is good but no volts or amps to the heater. I even replaced 3 relays but still no heat. Do you think I have to replace the element again or could it be something else.

[@VIPPoolsandSpas]

No volts or amps means its something on the circuit board. The board isnt doing its job sending volts to the element.

[@tanziwernholm7991]

What if i have a 240 system and have 240 coming in but only 120 at the element? I thought it was the element because one side got hot and melted so i replaced the whole set up. I did reuse the old wires because i have the clip in style not the bolt on kind of connection.

I have been working on a dream maker hot tub with a balboa circuit board in it. It's a 120 volt cord connected tub. After about 30 minutes it trips the GFCI cord end.

I have a hot tub that is not heating up. I was originally having issues with the gfi breaker tripping. I pulled the gfi and it would not reset so I replaced the gfi. After replacing that the hot tub heated to 95 degrees in 5-6 hours and than tripped the breaker. I let it cool to 80 degrees and restarted and the hot tub heated back to 95 and tripped the breaker. I unhooked the heater and ran the hot tub for 3 days with no issues. So I pulled the heater element and replaced it. I cannot get the hot tub to heat. It has been 3 days and it’s at 54 degrees. I have 240 volts coming in, 120 white to red and 120 white to black. At the heater with breaker on I have 240 volt and 17.5 amps (should be higher because I purchased a 5.5 kw element). I than turned the breaker off and I get a 0 ohm reading and no beep for continuity when the breaker is off. Any idea what the issue could be? Thank you Jay

GEE. A few things there. Was the old element a 4kw? I would change the element again. There's different issues here and I can't really pin point unless I was there. Something doesn't seem to like the heat

I have a head scratcher for you. I have a 20 yr old Hydrospa Millennium model. I had no heat. I had 120v to ground to each terminal on element. No 240v across both. The 4k ohm element checks out fine. I changed the filter and it worked for a few weeks. I changed the water and heat stopped again. Same symptoms came back. I jumped out the pressure switch and the heat worked. So I changed the the pressure switch to the newer #3902 switch. Still not working. I'm a licensed Electrician and I am stumped. Any idea's? Thanks

[@tonemizer]

BTW. I changed out the board after the first problem with the heat a few weeks ago. I noticed one of the copper tabs that connected the element to the board were burned at the board. I replaced the element a few years ago. I torqued the nuts at the element but I guess they loosened at the board side. I replaced the tabs with wire jumpers as recommended.

[@VIPPoolsandSpas]

Would have to know what spa pack you have in the hot tub. The words "spa pack" are sometimes used by electricians to describe the "breaker box", but hot tub techs call a spa pack the controls used under a hot tub. Take a picture and send to [e-mail]

It has {2} 2 speed 240 volt pumps plus {1} 115 volt circulating pump. All pumps are "working". I have 120v to ground on each terminal of the element, but 0 volts across both terms. When I temporarily jumped out the pressure switch, the heat came on and I got 240v across both terminals. Also, when I removed the filter, it did not correct the problem.

Please help ! I have a strongspa wirh Balboa VS501Z board. The circuit board has fried for the second time! The first technician simply replaced the circuit board and left two years ago. However, upon closer inspection this time, I noticed that the wiring to the hot tub is done with aluminum. So, I hired an electrician and opted for cheap and low AWG aluminum wiring. We then decided to change the entire wiring to copper, along with new breakers. However, the breaker started tripping with the new board. We conducted a test with the heater disconnected, and the hot tub started fine. We also replaced the heating element with a brand new one. Now, the hot tub starts for a few minutes, but then the circuit relay begins clicking and the jets intermittently work and eventually stop :( The pump was already changed last year. So brand new circuit board with brand new wiring with brand new heating element and one year old pump. I am really running out of ideas here ..

Assuming the pump thats pushing the water thru the heat tube is running, it would most likely be a relay. You can test by having one tester lead on the white coming into the pack and the other on one of the heater leads. There's 2 relays for the element. One might be gone.
