How to Troubleshoot Low Pressure on a Sears Craftsman Pressure Washer

Sears makes Craftsman pressure washers for cleaning large surfaces or those with hard-to-remove dirt and debris. Pressure washers can be used to clean the sides of houses, decks and large vehicles. For the pressure washer to work properly, it needs to shoot out water at high speed. If the washer has low pressure, the cleaning won't be as effective. Troubleshooting your pressure washer before tossing in the towel will help you determine which part of the machine may be causing the problem.
