I have a Kreepy Krauly Prowler 830. When I run it the orange filter light always comes on. I replaced the pleated filters thinking the old ones were too dirty and the light came on again. I ran the Krauler without any filters and the light came on. I have confirmed that there is nothing blocking the impeller fan or water exit.
Any suggestions on the cause/remediation? Not sure how it determines when to activate the light.
