Frequently Asked Questions

What causes Polaris ER 01 error to keep coming back?
Recurring ER 01 errors often indicate worn wheel bearings, a stretched drive belt, damaged wheel treads that catch debris easily, or inadequate pool skimming that allows too much debris to accumulate.
Can I prevent Polaris ER 01 errors from happening?
Yes, regularly skim your pool to remove large debris, clean your pool cleaner's filter and debris bag frequently, and inspect wheels monthly for wear. Also ensure proper water chemistry to prevent algae buildup that can clog mechanisms.
How do I know if my Polaris drive motor is actually broken?
If the ER 01 error persists after clearing all obstructions, the motor makes unusual grinding or clicking sounds, or the cleaner doesn't move even with free-spinning wheels, the drive motor may need professional diagnosis or replacement.
Is it safe to run my Polaris with an ER 01 error?
No, continuing to run with an ER 01 error can damage the drive motor permanently. The error is designed to protect the motor from burning out due to excessive strain from obstructions.
