Electric Water Boiler on Yom Tov

Rosewill 4.0 L Stainless Steel Electric Hot Water Dispenser

Seems to dispense water via electric button, rather than manual action.Would it be OK for use on Yom Tov?

Instructions for use with more details are here: https://images.homedepot-static.com/catalog/pdfImages/48/48e33cfc-5951-4314-840b-1c5569e82810.pdf

Thank you.
