Both lights blinking on level 1 charger?

One of the reasons I got a level 2 EVSE, no regrets.

I suspect that you had a power fluctuation that was severe enough to trigger the protective circuit. Unless it starts happening more often I wouldn't fret.

 

I have mine connected thru an APC line conditioner which controls and regulates 120V power - keeping brownouts and spikes from reaching the protected equipment....

 

See p 461 and 462 in the manual for details of what the different combinations of indicators signify.
Both Power and Charge blinking on the brick signify a rise in plug temperature due to a bad electrical contact at the outlet. The Clarity usually charges at a much lower level when this happens and the green charge light at the car charging port will stay green showing you’re getting some level of charge.
Can you tell us what it was indicating?

The Clarity can be overly sensitive to power fluctuations, especially at public EVSEs. If you haven’t had the all updates installed, especially Service Bulletin 18-097 for charging problems, you should.

I suggest you check the connection(s) at the outlet and extension cord (if used) and make sure they are tight and in good order. And for the next few charges, check and see if they are getting hot.

If that’s not the case and it’s just a one time affair, it may have been a power fluctuation from the grid and/or your house. In any event check those connections and make sure to get the 18-097 update.

Note that the 18-097 is not usually installed by a dealer unless you complain of charging problems. Evidently if they just do it without a reason, Honda won’t reimburse them. So the squeaky wheel gets the grease on this one and you can’t assume that it’s already been done.

I suppose we all have different interpretations of "a little warm" but it sounds OK to me.

 

I'd say a little warm is pretty normal, too hot to touch for several seconds is a problem.
