Hi my name is ***** ***** in the UK - left led flashing indicates that you have water in the base. If you remove the bottom kickstrip below the main door you will have access to the base area. With power off, old towell inside and dry it all out.
Sounds like you did have water in the base which had activated the flood protection device, tipping it back has reset the system which explains why it now is working.
