Not sure if this will help you but I have a DW1710E Smeg Dishwasher and I found the reset button on mine. Whether this is the same as yours you will find out. Behind the plinth, your dishwasher has a steel panel. I removed this and exposed the wiring, the reset button is red and at the leftmost part of the machine, on the "ceiling" of the bottom on the machine (if that makes sense!). Remember to switch off first. Good Luck.
