How do I stop my hot water pipes from hammering?

What causes hot water hammer?

Water hammer happens because water is shut off quickly. While sink, tub, and shower faucets can cause water hammer, more often clothes washers and dishwashers cause water hammer because they can shut off water faster than by hand. These appliances use solenoid valves, which can close off in as fast as 30 milliseconds.

Dishwashers and washing machines have a water supply that is controlled by solenoid valves. These are electrically operated and they stop the flow of water immediately.
