It is a pump, only motors are measured in Horsepower. I would expect the HP of this above ground combined pump and filter is so low they would be embarrassed to state. It is measured in Gallons Per Hour flow rate.

E 97 is an error code that indicates a dry fire protection system has been activated in your Intex Pure SPA. This means that the spa has sensed that there is not enough water in the system, and it has automatically shut down the heater to prevent damage.
To solve this problem, you will need to add more water to the spa. Once the water level is above the minimum level required for safe operation, the dry fire protection system should reset itself automatically.
It is not recommended to run the filtration and the bubbles or jets without enough water in the system as it can cause damage to the pump and other components. Therefore, make sure to add enough water before turning on any functions of the spa.
Also, make sure to check for any other causes that may have led to the water level dropping too low, such as a leak or drainage issue. If you continue to experience issues, refer to the owner's manual or contact Intex customer support for further assistance.
Question edited for clarity and typos.
If alarm code E97 is displayed on the control panel, it means there is a heater fuse error. If alarm code appears on the control panel, unplug and plug back in the GFCI/RCD and test the GFCI/RCD to restart the system. If the problem persists, please contact a Intex service center for assistance.
Salt generators take, on average, around 24 hours between adding salt and the system realizing or analyzing the data. A code 92 usually means salt levels are too high, but not always. It is best to take a water sample to a pool store for analysis to truly determine if that's the case. If so, draining some water and adding fresh water are the only real ways to rectify the salinity. Best wishes and hope this helps.
Probably bad control box for the jet motor/s if the motors are running could be bad pump or a pipe valve issue. Or is there a separate blower?motor that feeds the bubbles (air)
are you sure its not e99 water temp sensor because their is no 999 code for intex -----------turn off at gfi and unplug for about 5 minutes then plug back in unit some times glitches if code comes back same then notify intex [ good luck ] of code 999--any other code can be found in manual or online ----intex purespa code === ----
I had a problem similar the water flow was good but still coded E90 after 9 sec. I put a magnet next to the water flow sensor. Finally after a long time trying to diagnosing the problem this finally worked
I taped a magnet to it and put it he base back together. Been over a week now and it's still working!
For a test only, remove filters and see if you feel anything against the fitting?
If nothing either 'Air Lock', keeping it from priming the pump.
Or, bad pump!
Secondly, are you still dealing with a problem?
Use the comment link on this thread, and let the forum know if you are, if repaired, what did you do?
