What to do if my DeVilbiss Healthcare 525 unit does not operate?
- PPeter WilcoxAug 5, 2025
If your DeVilbiss Healthcare medical equipment unit isn't operating, and all lights are off while the power switch is on with a pulsing audible alert, check the power cord connection at the wall outlet. For 230 volt units, verify the mains connection on the back of the unit. Also, check your home circuit breaker and reset it if necessary. If the problem persists, try a different wall outlet. Press the concentrator circuit breaker reset button located below the power switch. If these steps don't resolve the issue, contact your DeVilbiss provider.
