I just read the Progressive instructions. The OP was having reverse polarity which is the wiring between hot and neutral being backwards. If open ground was involved it would read open ground or E3. It could be a open neutral/ poor connection somewhere in the electrical system causing voltage to appear on the neutral causing the issue.

I printed the progressive error codes on a note card size sheet and taped
it to the inside of my power center door.
It's already come in handy twice!!

Neither of the two campers who I spoke with that had noted they'd been aware of the multiple power interruptions that afternoon had any surge protection of their own. Their "unprotected" TTs were connected to the campground shore power directly. Neither of them, one of whom is a good friend, reported any adverse after-effect. Apparently no damage was done.

Because reverse polarity does not damage any appliances.

To have reverse polarity, wires must be fully reversed. Design that Progressive must use to detect reverse polarity can also report other anomalies (as described earlier). None involved or should be confused with a completely different anomaly - an open ground.

BTW, ground is another human safety layer and also not for protecting appliances.

Another way to look at reverse polarity not being a problem is to look at the old non-polarized plugs that came on everything. The equipment didn't care which way it was plugged in at all. The polarized plug came about for other (safety) issues.
