If you run hot water through the pump of a pressure washer, it will ruin the seals in the pump. The hot water causes their seals to swell, and the pistons will then rip them apart. Some machine are able to run hot water, but the have special seals inside. Ben - Great Lakes Cleaning Systems www.GreatLakesCleaningSystems.com
To connect a washer to the hot and cold water supply with a washer hookup, you need to first turn off the water supply, then attach the hoses from the washer to the corresponding hot and cold water valves.

If the shut off valve turns but does not shut the water off, the washer in it has split and probably made it to the faucet. It was blocking part of the hole on the hot side and at some point either shifted or made it through the faucet and in in the screen in the end of the spout. Shut the main water off and replace the washer in the shut off valve.
