Unplug the unit. The E90 code on the intex spa is due to a dirty water flow sensor. Remove the control panel and all the screw holding the casing on. In the white plastic piece on the discharge, top hose, you will see a silver nut with a black wire coming from it. That's the sensor. The black wire is plugged into a white wire, carefully unplug it and unscrew the sensor. Clean it good and blow out the hole it goes in. This will fix the code and you will be back in business!

    I have this problem also, I tried removing and cleaning sensor, but it did nothing. Any other ideas?

    I just completed this and I believe it solved my problem (so far so good). Please note I did this while the tub was full so water of course came shooting out so be prepared (you don't want that water getting into the exposed areas that are usually sealed off).

    Is the black tab on top of the silver band at intake B (shown here) what you mean as the sensor? Did anyone do a video re:this repair? We're not mechanically inclined and hoping to resolve this. Thanks!

    You need to take those 4 silver (philips head) screws out, lift off the back portion of the cover. You're not in deep enough yet.

    Mine does not have a screw or it is invaded in black resin is it possible to just unplug and bypass the sensor?

    where are you getting your info from, the sensor with the nut is a heat sensor the flow sensor is a black probe and is activated with a magnet under the white cover

Here's the problem after going through 5 control base's yes that's where the pump is located i was beyond mad that this keeps happening so i got my tools out and took the pump apart. Well i did find the problem and yes i fixed it. Here's the deal the pump has a impeller like your fish tank filter pump has in it well it spins on a shaft guess what the shaft is some cheap ol plastic that breaks. Beings that the impeller is magnetic you have to use something that is not magnetic so i bought some round brass rod at hobby lobby and made cut one to size put it back together and it works like a champ!! I have 4 others to fix and store away i may make a Youtube video just sucks that intex can't spend .25 cents and make these things stay going.

    I did this same thing and it worked perfectly. The axle thingy that they have on the impeller is made of plastic thinner than a lollipop stick, and just like you said it broke. Replaced it with a similar diameter brass rod from Ace Hardware, and just like you said, it fixed it!


    Thanks!

  • Brian Walsh
    Brian Walsh Mar 31, 2017

    Sean or Melanie, where are you located? I know how to do this, just need the right length. If you are close I will fix yours for free just to obtain the proper size for my own fix. If you are not close, can I walk you through how to open the pump up and measure it for me... and I can walk you through how to fix it for yourself?

  • Brian Walsh
    Brian Walsh Apr 01, 2017

    Fixed it! The length of the impeller should be cut to 2 7/8" for those of you who want to do it yourself.

    It's not plastic
    It's ceramic but I agree
    It's a bad design!
    Anything to control the impeller is fine but the inductet for the magnetic impeller goes bad also. Rebuilding the pump is in order sometimes and it's no fun!

    I used a brass welding rod in mine. Just broke off the outside layer, cut to size and works like a champ.

  • Mark McFeely Oct 20, 2017

    I've replaced with brass 3 times now, only lasts about 2 weeks, brass wears quicker than the original ceramic rod......can't seem to find ceramic rods 1/8" x 2 7/8" cheaply.....ones I do find cost almost as much as a new pump from intex which is $50+shipping.

    Where is the pump located please

  • Colin Dawson
    Colin Dawson Nov 19, 2017

    I tried cleaning out the no water flow sensor socket but no change, still got error E90 code. When I took the pump apart I found that the rotor was damaged and rusty. I purchased a new pump rotor and spindle from uk agent and changed it but when I switch on the pump it runs strongly for 10 to 15 seconds then cuts out with E90 error message. Anything else you think I might try?

    How did you take the pump apart? There are no screws and it looks like it's sealed. Thanks.

  • Robert Peters Feb 03, 2018

    First of all, it was the 12 volt pump UNDER the unit(SPJ-H-10-1); no need to remove the main shroud.3 screws hold both pump and its shroud in place; all that remains is to uncouple the water outlet by hand loosening the large nut and sliding it back toward the pump, then pull the pump toward you with a wiggle an out it comes, then disconnect its cord by unscrewing the securing nut and pulling out the plug. Now the 5 screws holding the pump together can be removed to separate the wetend and reveal the impeller which can now be drawn out from the housing. Quite likely the stationary plastic rod in its center will be in pieces and you'll likely need forceps to remove a piece at the bottom of the housing from the rubber bushing holding it. Now you can use a piece of 1/8" brazing rod to make the new shaft once the flux is removed and the rod is smooth. Start with it a bit overlength and insert both ends into their respective bushings and the gap between the mating surfaces will determine how much length to remove for the final fit. Once done, the impeller can be slipped in and the pump reassembled. Testing can be accomplished by pulling the cover off a regular 12 volt battery charger and connecting small jumpers to the secondary winding of its transformer at its center tap and one end of that winding to get the 12 VAC for the pump.

The water flow sensor is located next to the heating unit. You can rem9ve it with4 screws on the top. It apears to be a a contavt switch thay raises up to make contact when water flows thru.

I’m having the same problem with error code e90 I took the pump apart underneath the unit after going through a few steps
Replaced filter nope
Blowing it out the lines with a water pump nope
Still no water flow
Finally took part the pump shaft is good but magnetic motor and impeller damaged. The casing around the magnet was cracked . I tried to repair it and did a test run worked for a second. I wrote the company to find out if they could help me replace this part. The magnet is locking up so no water flow .
http://www.intexdevelopment.com/store/spas-replacement-parts or http://www.intexcorp.com/store/spas/replacement-parts
I hate to replace the lower unit for such a cheap part. Hopefully I get a answer soon. Also searching the internet magnetic motor and impeller. If this helps anyone or they can help me as well.

I recently bought a Pure Spa and within 30 minutes of operation I got the E90 error, the problem is that if there are any air bubbles in the filters it will not flow water and give the error.

Just take off the filters, shake them around under the water to remove the trapped air and put them back on - that's all it takes. I was going to send the tub back, its amazing that Intex doesn't know about this issue.

Thanks!

SOURCE: We have a LED code showing on the new Intex pure spa. E97 Dry-fire Protection. What does it mean

Dry fire protection is when the heater has a call to heat but it is sensing NO water flow, therefore heater will be disabled.

A dry fire is when the heater comes on with NO water flow - damaging your heater beyond repair.

Causes: No water in tub, closed valves, clog restricting water flow, or the pressure/flow switch had failed?

SOURCE: I've got an Intex pure spa hot tub and the air bubbles button isn't working but the LED screen is on??? Any suggestions?

  • Do the other buttons work fine?
  • Did you press REALLY hard and break it
  • Have you tried pressing it REALLY hard when its not broken- Probably a bad idea
  • if you have the know how and the bravery take the face plate off (MAKE SURE THE POWER IS OFF AND THE WHOLE THING IS UNPLUGGED)!!!!!1
  • check the wires going to the back panel of the screen Rusted, corroded? Might be covered under warranty - refer to manual or look-up based on how long you've had unit

Pump is not pumping water on intex purespa error E90, what could be the problem?


I to have run into this issue and i saw a repair using a piece of brass rod. If you open the motor cap where the impeller is located you will find the impeller guide shaft is made of a cheep piece of plastic and has broken it is a magnetic motor guided assembly and all it does is hold the impeller in the exact place. well i have found just the piece that you can fashion a quick fix from and you can find it at any hardware store. I happened to get mine from home Depot. buy a toilet handle brass lift kit paid 3.00 for it.
the larger piece is a perfect fit cut it to size and file the end of any sharp edges. works great
