The hazard: Carbon monoxide poisoning hazard

The recall concerns carbon monoxide release. Because the gas is odourless, the usual advice to stop using a product if it smells wrong simply does not apply here.

What the notice says: During operation, the heaters can produce high levels of carbon monoxide (CO), posing a risk of serious injury or death from carbon monoxide poisoning.

Why it matters: The product can release carbon monoxide, a gas with no colour, smell or taste. People who are asleep or intoxicated can die from it before anyone notices anything is wrong.

Symptoms and when to call a doctor

The CDC describes carbon monoxide poisoning as headache, dizziness, weakness, nausea, vomiting, chest pain and confusion — easily mistaken for flu, but without a fever. If you suspect it, get everyone outside into fresh air first, then call 911. Tell the crew that CO is suspected. A key clue is several people, or the pets, feeling ill at the same time, and feeling better once they leave the building.

What to do about Carbon monoxide

Hayward Industries — The recall concerns carbon monoxide release. Because the gas is odourless, the usual advice to stop using a product if it smells wrong simply does not apply here.

  2. Fit a working carbon monoxide alarm on every sleeping level and test it; it is a few dollars and it is the only warning you will get.

  4. Follow the remedy on this page and keep the unit out of use until it is done.

If the claim stalls

Most recall claims are paid without argument. The ones that stall usually stall for a reason you can fix.

  • Check you used the recall channel rather than ordinary customer support — the two queues rarely talk to each other.
  • Send the photos they asked for in the format they asked for. A missing date code is the single commonest reason a claim sits unprocessed.
  • Give it ten working days, then chase in writing and quote your claim reference.
  • If the company is unresponsive or has stopped trading, report it to the CPSC at SaferProducts.gov, and try the retailer in parallel.

Remedy named in the notice: Consumers should stop using the pool heater immediately and contact Hayward Industries to schedule a free in-home inspection and repair by a qualified technician.
