Repairing heating coils in a steam cleaner?

Question:I bought a steam cleaner and the coils which the water flows through leak a little in a spot or two. How can I repair these leaks?They are not by any fittings.

Answers:
I don't know what brand cleaner you have. But if it's a Hoover, the heater is replaced as a unit. I replace them where I work when they no longer heat, leak, or are severely clogged.
