What kind of recall is this?

The U.S. Consumer Product Safety Commission (CPSC) issues recalls for consumer products that pose a substantial risk of injury or death. Unlike food and drug recalls, CPSC recalls do not use a numbered class system — instead, the notice describes the specific hazard (for example: fire, burn, laceration, entrapment, choking, or tip-over). The hazard for this recall is listed above. Stop using the product until you have completed the remedy the manufacturer offers, which is typically a free repair, replacement, or refund.

What should you do now?

1. Stop using the product immediately. Set it aside somewhere it can't be used accidentally by another member of your household.
2. Confirm you have an affected unit. Match the model number, lot code, date of manufacture, or serial number to the list above. If the details don't match, your unit is likely not part of this recall.
3. Contact Hayward Industries, Inc., of Charlotte, North Carolina for the remedy. The manufacturer is required to offer a free repair, replacement, or refund. Contact details are listed below.
4. Add the product to Recalled.co so you get an alert automatically if a follow-up recall or expansion is issued for the same product family.
