After removing the particulate filter, thorough cleaning is necessary. Using a hose, immerse the filter in a bowl of water and run a jet of water through the inlet pipe, repeating the process until the water runs clear.

For better cleaning, use a high-pressure water jet, directing the water through the inlet pipe to remove any remaining dirt. Once cleaning is complete, refit the filter in its housing, tightening all nuts and clamps on the inlet pipe securely.
