  Cole SmithNov 22, 2025
  To troubleshoot low operating pressure in your Hotsy Pressure Washer, start by checking for common issues. Ensure you have a sufficient water supply, using a larger supply hose and cleaning the filter at the water inlet. Inspect the spray nozzle; it might be old, worn, or incorrect, so match the nozzle number to your machine or replace it. Also, check for belt slippage and tighten or replace the belt if needed, ensuring you use the correct belt. Examine the plumbing system for leaks and re-tape any leaks with Teflon tape. Other potential causes include a faulty pressure gauge (install a new gauge), worn packing in the pump (install a new packing kit), fouled or dirty inlet or discharge valves in the pump (clean them), worn inlet or discharge valves (replace with a valve kit), an obstructio...
