F02 error code

Hi,
The reason for F02 error is due to something stuck inside. Pop off the front cover (3 Torx screws on the bottom lip) After removing the cover you will see a white plastic unit with a screw on cover on the front. Unscrew the cover (no tools needed). Pull the cover off then remove the strainer. It will have gray gook on it plus God knows what else. Clean the strainer in the sink replace screw the cover back on and your in business
Thanks for contacting Fixya.
