Intex Pool Heater Repair and Modify Outlets (2023)


This video covers how to repair a Intex swimming pool heater that's suddenly stopped working. End of the video shows you how to adjust the inlet and outlets to your desired configuration. Would possible work for Bestway pool heater


So if you've got an intex pool, heater, that's suddenly stopped working I'm going to show you how to fix it in this simple video coming up, right after this.

So this unit's about four years old and worked quite happily.

But this light here stopped coming on, and it stopped producing any heat.

So I checked the fuses all the rest of it, but it wasn't, uh, coming back on.

So what we're going to do is we're going to use an allen key just to sort of open up the top.

Now you've got a screw there on the side to remove to expose the electrics.

And we've also got a screw there to expose the heating element.

So we're just going to pop that off.

Now I found man was quite rusty.

So I had to use a pair of pliers because it wasn't coming off.

So that simply unscrews clean after four years use, um, there is a bit of scale on it.

So you might want to use a descaler.

So you can see that the actual heater element itself is pretty clean, get yourself a very small phillips because it's quite a delicate screw and just carefully remove those two screws.

So as you can see it's kind of rough so it's, not full of dirt dirt as it were it's, just kind of very fine scale deposits, which is preventing that from moving up and down.

So we put a bit of ipa on there and give that a clean as you can see that's now moving quite freely.

But what we can do is there's like an end, stopper that's clipped on the end.

So if we kind of pop that off, it allows us to take the whole unit apart.

So we can give it a good clean properly.

So just use your fingers and grab that and pull it off don't lose it.

As you can see there's a magnetic end.

And the magnetic end always goes at the top.

So remember that so don't get it the wrong way around, and then just use the ipa just to give that whole stick a good clean also give the inside a good clean as well.

Now, yet, again, this clear part seems to get gritty so use the ipa just to get that nice and clean.

So you see it's quite dirty.

So just use a microfiber towel just to dry it all off and give it a good clean, even though with the ipa, it should clean itself off.

Anyway, just give it a good rub.

Just to make sure everything's off there.

You go much better, and then just stick the earbud inside there, just to give that a quick dry out.

I see much better so we'll just put it back together.


So just remember that the magnetic part goes at the top pop the clip back in and then pop the cover back on, and that should be moving quite freely.


So pop your two screws back in just give the whole thing.

I find the ipa doesn't remove scale.

So you might want to use like a kettle descaler or something like that, if yours is really bad, but man was pretty clean to be honest.

I thought, well, while we're, actually taking it apart.

What would be a good idea is actually to clean those rubber seals? Now you might want to use a bit of rubber silicon here.

If you've got any, I just use a bit of ipa and just give it a wipe with the cloth and just pop the seal back in.

And the other seal is at the top so pop that off, and then give that a clean as well it's in pretty good condition, considering it's, four years old.

But I suppose it is only used for sort of four or five months out of the year.

Now there is a certain way that this goes back on.

And then it locks in place and then drop the whole thing back down don't, forget to put your screws in for the electronics.

At the top make sure that's nice and tight.

The screws are delicate so don't do them too tight, otherwise you'll cross thread them and then get the plastic housing, and then just pop that back on and the same with the top and don't forget to put your locking screws back in either.

Now, what I've done is I've sealed off the bottom, and I've applied power to it so we're going to get some water and fill it up and actually see if it lights up and voila, there, it is it's gone red.

So there we are fixed and that's all it is it's just a faulty float.

So I've plumbed it all back into the swimming pool area.

So for a real live test rather than a sync test, and there you go it's back on.

And that is how you fix an intex, pull heater that suddenly stopped working now in the next part of the video I'm going to cover a modification.

I made now.

The one thing that's always annoyed me about the design of this pull heater is the inlet and outlet is on the same side.

So the way my pumps are placed is always behind, which means I've got to basically run the pipe round, the heater, obviously on one side, it's, fine, because it goes straight out, but under the bottom coming around and there's, a bend on the pipe, trying to figure out a way of turning it around because it's actually locked in place.

So if you spin the top off again, what you will find is there is a notch.

And there is only one notch, which means it will only go one way, there's, no notch on the other side.

Now that notch is also below the rubber seal and there's the notch there.

So what you want to do is get a knife or a dremel or something just to remove that notch.

So we want it to go that way.

So basically you've got water coming in from the left hand side.

And then the output goes on the right hand side.

So that my filter can sit at the left, and then the output to the pull goes to the right.

I don't understand why they would design it both in and out on the same way.

So rather than modifying the base.

We can just use a knife or a dremel, or something just to sort of cut that notch off.

Now be careful with the knife, because it is reasonably hard.

Plastic dremel might be a better bet.

But if you use a sharp stanley blade, you can actually cut that notch off once I've made the cut.

Then I just used a pair of pliers just to remove it off.

It doesn't sit totally flush with the bottom anyway.

So just smooth that off.

And then that allows us to put it the other way.

So because it still sits above the rubber seal once it's screwed in tightly with the ring, it's, still perfectly water tight and doesn't leak.

So now that notch is gone.

We can then pop the top on and run it the other way so get the ring tighten that up.

Now, the one thing I did find is now that the notch is there it's, not perfectly as I was tightening.

It I'm actually, moved it around slightly.

So I just have to undo it again, just to line it up.

And there we go that'll be leak free.

So there we go.

So we've got the inlet at the bottom coming in, and then the outlet at the top, and that is how they should have designed it.

I just do not know why they would put it on that way around.

So that brings us to the end of the video.

I hope you found it interesting and informative smash that like button.

If you so desire and leave me a comment with any feedback, or if you any problems that you've had and how you fixed it, I do appreciate it.

So until next time, see you later.
