The good news is that resetting any Zanussi dishwasher model is straightforward, and you can do it yourself.
Reset Zanussi Dishwasher
To reset your Zanussi dishwasher, first, turn it off. After that, unplug your dishwasher and wait for full 5 minutes. After 5 minutes, plug your dishwasher back in.
This will restore your Zanussi dishwasher to its settings when you purchased it.
If it does not, then again, unplug your dishwasher. When it is unplugged, press and hold power/start button for a few seconds to drain the residual power and see it reset.
