The answer to 'my pressure washing is filthy' is that there are several common causes for a dirty pressure washer, including clogged nozzles, worn parts, and buildup of dirt and debris. Symptoms can include reduced water pressure, uneven spray patterns, and poor cleaning performance. To troubleshoot and fix the issue, you may need to clean the nozzle, replace worn parts like the pump or hoses, and thoroughly clean the entire system.
For minor issues, you can often handle pressure washer maintenance and cleaning yourself. However, for more complex problems or if you're not comfortable working on the equipment, it's best to call a professional cleaning technician to inspect and service the pressure washer. They have the expertise and tools to properly diagnose and repair the problem.
