Hi all I’m new to the forum and interested in some of the questions asked here. I have worked in the electrical trade for some years so I’m no stranger to electricity and circuit boards, my question is I have just moved a Hoover Ultima wmd960p from one house to another and when it was plumbed back in it comes up Fault code F09 after checking it says EPROM needs resetting is it a case of checking the board is in its slot properly or doe’s it need some secret code pressed on the buttons to reset it as some other electrical products do, also why should it do this after moving it. Any help will be appreciated. Regards Kindwarf.
