CPSC recalls Hayward HDFS400 pool heaters for CO risk

The Situation

On Sept. 17, 2026, the U.S. Consumer Product Safety Commission posted Fast Track recall 26-777. CPSC says Hayward Industries recalls HDFS400 Universal-HC Series 400,000 BTU dual-fuel gas pool heaters. The recall notice says the heaters "can produce high levels of carbon monoxide".

The Facts

About 4,600 units are covered, CPSC says. CPSC says sales ran through pool distributors, builders, and service pros nationwide from March 2026 through July 2026.

Consumers should stop using the heater at once. Contact Hayward for a free in-home check and fix by a qualified tech, the recall notice says. No incidents were reported.

The units are brown with a black top. The name plate sits under the vent, with "HDFS400" at the top and "Hayward" at the bottom, CPSC says.

Business Impact

Dealer guidance, not reported news: Brief service techs and customer-service staff on the HDFS400 name plate. When a pool customer calls, hand the case to Hayward.

Hayward's qualified technician handles the work.

Key Takeaways

• Brief the desk before pool heater calls rise.
• You stay ready when staff know the handoff to the maker.
• Train the front desk on what to say first.

Action Steps

2. 2.Train staff on the maker handoff when a pool heater call comes in.
3. 3.Put a copy of the recall notice at the desk for callers who want the official page.

Competitive Advantage

Staff who can name the model and send the caller to the maker are ready for that call.
