Incident narrative

SaferProducts.gov consumer incident report 20260528-D6DA1-2147318463. Severity: Incident, No Injury. Product: Dyson HP04 (Dyson Pure Hot+Cool HP04 purifying heater + fan). Incident: My Dyson Pure Hot+Cool HP04 purifying heater + fan showed charring, discoloration, and melting on its white plastic rim. There was a serious risk of fire and/or injury if I had not noticed the charring before touching the machine. Fortunately, no injuries occurred. The machine was running on standard heat mode set at 70 degrees Fahrenheit. The Dyson machine was not placed near a radiator or fireplace, nor was it covered with any foreign object. It was being used in accordance with manufacturer guidelines. I had purchased the machine new from Costco in November 2021. The manufacturer (Dyson Escalation Team) keeps insisting that "This is not considered a product fault, and there is no safety risk associated with the issue." I disagree. On April 11, 2026, the Dyson Escalation Team offered to replace the machine with a refurbished, similar model, and I agreed to the replacement and provided them with my shipping information so that an exchange order and return label would be generated. Unfortunately, since then, Dyson has not honored its offer and has ignored multiple follow-up emails from me. I finally asked in writing for a senior manager to contact me and honor their offer, and still zero response from Dyson. Description of Risk of Harm: the device's plastic casing was melted and charred, indicating high, concentrated heat beyond the device's design limits. Had I not noticed the issue in time, there was a risk of harm to me from (1) unsafe fumes from melting plastic that I would have inhaled continuously while sleeping and/or (2) a fire igniting at the device's location insi
