REMstar Plus Cflex Error Code 8

I was just checking my machine out to see what the cflex setting was on after reading what the settings meant. I got it into setup mode and instead of what it should be showing it showed everything at once all over the screen. When I hit the arrow to move through settings it said E-8 and it definitely looked messed up. I exited the setup mode. I turned the machine on and it shows my correct pressure and everything. I'm wondering if anyone knows what that error code means??? Everything seems to be working okay.

Check to see if one of the buttons may be caught/stuck/cocked under the cover where it can be pushed down.
If you can't see it, you might want to unplug it and push every button and see if one of them is stuck and then plug it back in and see what happens. If that doesn't do it, you will probably have to take it back to your DME.

Here's what's in the Service Manual for that machine.

Good luck.

E-8

Key stuck - One of the keys is stuck in the closed position

Verify that nothing is pressing a key.
Replace control pad
If error persists, replace main PCA
