Unable to Access Menu of Epson Workforce 645?

Hi, I had attempted to scan using a Epson Workforce 645 all in one printer, but it had an error partway through and did not complete. It is possible this was due to water after I tried to clean the surface. It is now flashing lights and showing a scanner error message which states to turn it off and restart, but that does not solve the issue. The error message also prevents me from accessing the menu, so I want to be able to solve that if nothing else to make sure I can use the other functions. Any help is appreciated.
