It's because clicking the button 5 times (or maybe it's 10?) causes the wall connector to reboot and enable it's management WiFi network for configuration. You can either do that or cycle the breaker which feeds it.

Tesla wall connector gen3 overheating fix

Its actually HOLDING the button for five seconds that does the reboot. I'm not sure if multiple presses are counted as a continuous press, but its certainly a good possibility.

Hmmm. I know holding it down does that, but the three red blinking lights don’t show when you hold the button down do they? I thought just the green started pulsing.

Since my earlier post on this thread, my WC has started having the 3 blinking red light/dropping amps issues. I called Tesla last week and after a quick diagnosis, they are sending me the new 24' Gen 3 charger! Which is awesome because I originally ordered a 24' Gen 2, but was delivered an 18' Gen 3.
Hopefully the new hardware fixes the overheating gremlins.

Sad to report that I am joining the list of red three blink Gen 3 Wall Connector issues. I have had it for almost 2 years without issue until yesterday. Tried uploading new firmware, said it was successful, did not work. Tried breaker off and on, did not work. Noticeably, the Tesla app had already registered the error so it was very easy to request mobile service, which is now scheduled to come out on Wednesday afternoon.

Seems like anything pre-G is an issue potentially.
Honestly, I'm not familiar with the term "pre-G." This is a 18' Cable Wall Connector ordered on March 31, 2020. SKU: 1457768-01-F
I assume they mean the -F on the end of your SKU. F comes before G so you are probably in the range of units that have the problem.
Any wall connector with a revision before G exhibits the problem. You have a F. You potentially have one with the issue.

Update on this: service messages within the Tesla app indicate that this is not able to be looked at by Mobile Service, and to call the number for HPWC support or email directly. Tried calling the number on my short lunch break and it was a 15+ minute wait. Will try again after work. Ugh.
Okay, here's where this ended: took a 21 minute phone call (on hold for about 7 minutes). New HPWC being sent out to me (24', so 6 extra feet from what I currently had), and service guy said it should just snap on to the current framing and be pretty easy to install (no electrician needed). It was a fair amount of time before we got there, though. He pulled all the recent charging logs from my car and asked a decent amount of questions. Eventually stated that the charging handle must have had some overheating wiring in it. Covered by warranty, so replaced for free. I do have to send the old one back to be recycled.
It is easy to just replace the unit. No need to replace the backplate, which is very difficult. The front just snaps in after removing some screws. Just turn off the breaker and test to make sure it is off at the unit itself before starting Then recommission the unit following the instructions. Done.

Yup. Takes under 2 mins. 4 screws, two top/two bottom, lift unit off wall. Place new unit on wall. Attach 4 screws. Done. So easy. As @DerbyDave stated, just switch off breaker first.
Good time to check to make sure that all of the connections are still torqued down. (Please double make sure the breaker is off. If you have other people around lock out tag/out would be your friend).
Final update for me on this: just received the Gen 3 wall connector version G from FedEx. As others have said, very simple install physically. A bit strange on the WiFi connection bit, because once I uploaded the latest firmware for it, the connection page just spun in a circle and there was no way to see the details, set amperage, etc. Tried resetting breakers, connecting to WiFi again, nothing.
