What the heck is this dingus on the end of my new dishwasher's hose likely to be for? I can make out "type 88" in the plastic moulding but both google and bing insisted I want to learn about main battle tanks instead. My best guess is that it's a temperature or flow rate sensor. I'm mildly excited by the need to add a hole saw to my tool collection, but I don't quite understand what purpose it serves being outside of the machine itself.
