I use a
Respironics BiPAP ST (New Grey Model) with Heated Humidifier. Last night the alarm went off 2x with the H20 icon flashing. The manual says that means a blockage or leak. Checked, never found 1. Then, the alarm went off a 3rd time. This time the machine stopped blowing air & gave the error message E41. All the manual said was unplug the power then plug it back up & to call my provider if it kept on. After plugging it back in it restarted & I slept 4 more hours (till I woke up on my own) with no more alarms. I'm a nervous wreck to go back to sleep tonight, afraid it'll act up again. Does anyone know what the error message means (the user manual didn't say)

I really don't want to have to call my provider again because it's not been 4-5 weeks since my other machine quit (I'd had it a little over 3 years) & they had to replace it with the current 1. I'm afraid if I keep having issues my insurance will stop covering it.
