Has anyone else felt that their pitcher of milk was in danger of being flooded with hot water from a steam wand that shoots out hot water and steam? When I start my machine up in the morning, I let it heat up for about an hour before I use it. Lately, I've had to purge the steam wand for about 10 seconds before I can get consistent steam without random spurts of hot water. But, even after I do that, I still get these random spurts of hot water shot into my milk.

I always purge before and after each steaming, and I soak the tip of the wand for about 20 minutes at the end of using it.

Any tips?

This usually means the boiler is overfilled. On a machine with autofill, the probe level may be set too high, or reading too high because of scale.

To elaborate on Bob's point, scale can slowly build up on the water level sensor probe, resulting in a progressively higher water level. Eventually this leads to wet steam. Chris' Coffee FAQ How to properly replace a liquid level sensor probe provides good removal instructions, caveats, and photo.
