To reset all slots you can define a custom action:

```
class ActionFlushSlots(Action):

    def name(self) -> Text:
        return "action_flush_slots"

    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

        slots = []
        for key, value in tracker.current_slot_values().items():
            if value is not None:
                slots.append(SlotSet(key=key, value=None))

        return slots

```

You can invoke this action wherever you want in your stories and rules. Alternatively, you can add to your `validate` function the lines of code inside the `run` method above.
