If your goal is just to fill the reservoir automatically from a plumbed-in water source, without monitoring/logging water levels, a small float valve like this[0] might be a good answer too. I don't know how big the reservoir in your machine is, nor do I know if this particular valve is food-safe. You should definitely fix that light though. That sensor may also be part of a safety cutoff to prevent burning out the element.

This was from a quick search, I know nothing about this particular valve.
