I could not find anything about a Red Blinking Light in the Charging Port and an associated failing to charge. The manual speaks to three colors, see below. Failed once with red light. Failed second time with red light. Both times, after connecting to my home charger, it appeared to start normally. The third time the charging continued with no failure and no red light. The second time I made sure that the connection to the car was solid, thinking perhaps the first time I failed to click it in. Not sure, at this point, is it the car, the charger, or the connection point not connecting solidly. Using a can of compressed air, after the charge completed, I applied air to both the port and the plug. I would hate to be on the road, needing a charge and have this occur with no knowledge of what the cause is.

From the manual:
"There are three charge port indicator light colors, which indicate a specific action:
White is used as a courtesy light to help with plugging in and to acknowledge actions such as plugging in and unplugging.
Blue is used when the vehicle is plugged in and either charging or waiting to charge.
Amber is used to indicate charge faults.

Note: Charging faults are identified by the color amber on the charge status indicator. Faults can occur within the vehicle charging system or outside the vehicle, such as with the mobile power cord, charge station or electrical supply.
Note: If the system detects a fault in the vehicle charging system at any point in a charge cycle, the entire charge status indicator illuminates solidly in an amber color for 30 seconds and then turns off. If this happens, unplug the charge coupler and then plug it back into the charge port receptacle. If the problem persists, have your vehicle serviced as soon as possible.
Note: If the system detects a fault outside the vehicle, such as with the charge station or mobile power cord, the entire charge status indicator flashes amber continuously for 30 seconds and then turns off. If this happens check the mobile power cord, charge station or electrical supply."

I have no experience myself but based on what you have shared it is indicative of something wrong with the EVSE, chord, or electrical supply. What EVSE are you using and do you have the ability to test it with another?

If you had fault indications in your car hopefully you followed @Mach-Lee suggestions. If you have any error lights on the EVSE; however, it may just be your charger has a problem. I would certainly test with another L2 if possible.

Red light charging failure again last night. I unplugged, waited, plugged back in, and it started to charge again. I have a meter measuring current from the charger, and it was charging at 11+ kWh. I waited a couple of minutes, feeling the lines from the plug to the charger and the charger to the car. No heat. Then the light appeared again and charging stopped. Last night we drove in rain and snow, and I noticed that there was water around the charger door opening when after the failure. My garage is attached and was 55 degrees. I used a can of compressed air on the plug and the port. I then plugged in and it started charging again, getting up to 11+kWh. As it continues to charge, the line to the charger and the car are both slightly warm and I notice a slight hum at the charger. I am wondering if the seal on the charger port door is allowing some moisture to condense in the charger port? On the way to our destination last night the snow caused us to lose all sensors for adaptive cruise control. Any thoughts?

I've been getting this every time I charge since about mid August. When I first plug in the car, it will charge for 2-3 minutes then blink red and stop charging. If I unplug it, wait 10-20 seconds, plug it back in, then it will charge fine (95% of the time. Every once in a while it'll do the red blinking ring again after 2-3 minutes again).
I've tested this on a few different charges, here's what I've noticed, anything higher than about 7kwh, it will do this, anything lower than 7kwh it will charge fine on the first attempt.
At first I thought it was my emporia EVSE, contacted support, they sent a replacement unit. Still does the same thing. Tested on a Ford pro charger (the one that came with F150 lightning), and it did the same thing. Tested on a few public L2 chargers that maxed out at 6.6kwh and none of them had this issue. Lowered my empoira to 6kwh and it charged fine. Raised it to 7kwh and it started to do this red ring again.
It seems some software update in August caused my MME to not like initial charge rates above 7kwh.

Back in August you had this issue, you got suggestions as to how to resolve, and then nothing was posted back. What did you do back then?

Snow on the bumper - no issue for charging
Water inside the door - no issue for charging
Water blown by compressed air into the innards - possible issue?

Has your car been updated recently?

In August I used the compressed air and waited a bit and it worked. I have not tried the advice given in August yet. I did not blow compressed canned air into the port and plug until after the red light appeared twice. I just tried it again and it failed, waited, canned compressed air it again, and it seems is still charging 15 minutes later. Last Update 10/12/23 6.1.0 I did not think snow on the bumper was an issue for charging, I just wanted to point out how slushy the snow was.

My initial charge rate starts at 1 kWh and builds to the 11+. Have you worked with Ford yet on this?

My local ford dealers are clueless on anything EV related. So no luck with them. Plus my car has almost 42k miles on it so it's out of factory warranty (Still under Ford extended warranty) So dealers don't even want to touch it.

I’ll let you know on this post what I find out. I have a Ford Connect Charger, so technically I’ll be dealing with one vendor, FORD.

My light flashed red at a BP (EVGO/Arco) DCFC as soon as I plugged it in. I received a charge fault message in FordPass about 10 minutes after.

As soon as I noticed the red, I unplugged and plugged back in. The charging station never recognized that I had plugged it into the car, the screen just kept the message "Plug in to start charging". After this red light, no charger would connect. I can't charge at DCFC or slow/home charge. My light only shows solid white now, which according to the manual is a convenience light to help see in the dark.
