Error code 90 on my Intex spa even after buying and replacing new pump . Checked for blockages but everything is clear. Got clean water in and new filter
The E90 code on the Intex spa is due to a dirty water flow 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 https://www.justanswer.com/pool-and-spa/ap9qh-i-m-having-error-code-90-intex-hot-tub-intex.html
