E18 indicates a blockage or problem in the drainage system.
Firstly, please remove and clean out the filter and aperture bottom right of the machine - have a tray and some towels ready to catch any water that comes out when you unscrew this. Once cleaned out see if the E18 has been cleared.
I hope that helps, Best Regards,
