help please, this gives no sense to me that it ain't working

water="on"
function await()
repeat
  event, param1 = os.pullEvent()
  if water=="on" then
    water="off"
  elseif water=="off" then
    water="on"
  end
until event=="char" and param1=="17"
watercontrol()
end
function watercontrol()
  term.clear()
  term.setCursorPos(10,5)
  write("W: ")
  if water=="on" then
    redstone.setOutput("left", true)
    print("Water cooling: ".. water .. " ")
  elseif water=="off" then
    redstone.setOutput("left", false)
    print("Water cooling: ".. water)
  end
await()
end
watercontrol()

until event == "char" and param1 == "17"

until event == "key" and param1 == 17

until event == "char" and param1 == "w"

You're using the event system wrong

until event == "char" and param1 == "17"

because this would never be possible, the event 'char' returns the key pressed by it's id or what you could call it, so for example if I pressed the spacebar it would return ' ', now if I used "key" instead of "char" it would return 57 which is the keycode for spacebar( if I remember correctly )
So basically to fix that part you would have to change it to

until event == "key" and param1 == 17

or

until event == "key" and param1 == "w"

Now I agree with Cranium, a little more information would be good

You made a mistake, the second one has to be "char".
