This error code refers to a time out for either fill or empty. The program control allows a set time, by which if it hasn’t received the signal that the dishwasher has filled up with the right level of water, or conversely that the dishwasher hasn’t emptied all the water properly it will time out and display E10.

This is an old one, relevant to the old Hoover New Wave washing machines.

E1 = timed out on either fill, heat or draining. This is a typically ambiguous and confusing error code in that it is shared by 3 totally separate and unconnected types of fault instead of having a separate error code for each fault.
