The display flashing RED is an indication of a SYSTEM ERROR. Open the "iHome Clean" app > tap on the iHome AUTOVAC Eclipse and arrive on the home screen. Tap on the "Device Notifications" icon located at the top right of the screen (looks like a bell). The error message will be listed.
Most system errors are maintenance related. Please select the videos tab to view instructional maintenance videos to keep your AUTOVAC functioning at an optimal level.
