Try the sequence you’ll describe to guests on the actual model in the property. Use the words or symbols shown on its controls. “Press Start/Pause” helps if that button exists; “press the button on the right” can become ambiguous as soon as you replace the appliance.
Start with the everyday task your guest wants to do. For a dishwasher, that might mean where to find the right detergent, which programme you use and how to start it. Keep less common functions in the manufacturer’s manual, linked from the same instruction sheet.
Airbnb recommends including practical appliance and amenity instructions in a house manual. For your property, the useful work is turning the actual controls into a sequence someone who has just arrived can follow.
