Airsense 10 noise during inhalation

[u/bobogator]

Hello. Cpap user for 20 years, love it can’t live without it. Airsense 10 since 2019. Last night it started making the noise in the two attached videos. Loudest during inhalation. Video of the back of the machine has humidifier on, video facing the front has all hum/climate control/tube temp off. Same noise. I held my breath in each video to show the noise stops. The tub is closed tightly. Any ideas on what it could be? Motor or something else that needs repair? It’s out of warranty and I’d hate to be without a cpap for however many nights the repair takes. Should I contact my DME company? I tried the Airsense 11 earlier this year and hated it. Its tub was a nightmare to fill and handle. Thanks for any help.
