What to do if your Polaris 380 is not working?

If your Polaris 380 pool cleaner is not working, start by checking the pressure relief valve to ensure it’s releasing water, as a blockage here could impede the cleaner’s function. If it’s not releasing water, proceed to clean or backwash your pool filter to remove any obstructions. Additionally, examine the filter screen in the in-line filter for clogs and clean it if necessary. It’s also important to verify that the float hose is the correct length for your pool, as an improper length can restrict the cleaner’s range and effectiveness.

Should the Polaris 380 still not clean the entire pool or seems to be running slowly, inspect the wheel RPM to make sure it is within the proper range. If the RPM is higher than 32, unscrew the pressure relief valve to decrease water flow to the cleaner. Ensure that the back-up valve is cycling properly; it should turn on and off as the cleaner operates. Also, check that the thrust jet is set to the 11:00 position to optimize random turning. If the cleaner hangs up on steps or other obstacles for longer than 3 minutes, consider removing unnecessary pool hardware or installing a Ladder Guard Kit.

Following these troubleshooting steps should help resolve most issues with the Polaris 380 pool cleaner. If the problem persists, consult the user manual or contact customer support for further assistance.
