I unplugged my home charging cable today to use the outlet for a power washer. When I plugged it back in, the white LED ring lights up, then starts flashing red. I've tried a couple different outlets (probably on the same circuit though) and get the same result. I've left it plugged into the wall for a few min and it just keeps flashing red. Any ideas? The car was fully charged (set to 90%) when I disconnected it.
