Check the O-rings and seals around these valves. If they appear worn, it’s wise to replace them to ensure a proper fit when reassembled.
After removing the valves, you can access the pistons and other internal mechanisms. Gently pull these parts out, taking care not to force anything that feels stuck. If they resist, double-check for any remaining screws or clips.
Once all components are removed, clean each part thoroughly with a suitable solvent. This removes any build-up that could affect performance once reassembled.
Keep everything organised, as this will make reassembly straightforward. Label each component if necessary, and make notes on any issues observed during disassembly for reference later.

Inspecting Internal Components for Damage
Check every component meticulously for signs of wear or failure. Begin with the pistons; look for scratches or scoring on the surface. These imperfections can compromise sealing and lead to pressure drop. If you notice any damage, replacing the pistons may be necessary.
Valves and Seals Examination
Next, inspect the inlet and outlet valves. A bent or damaged valve can prevent proper water flow, causing inefficiency. Ensure the seals are intact; cracked or worn seals can lead to leaks. If you find any, replacing them is straightforward and can significantly improve performance.
Crankshaft and Connecting Rod Assessment
Examine the crankshaft for any signs of bending or excessive wear. A misaligned crankshaft can create operational issues. The connecting rod should be free of cracks and should move smoothly. If there’s any play or roughness in movement, it’s a sign that these components need attention.
Replacing Worn Seals and O-Rings
Start by gathering the correct replacement seals and O-rings for your model. Check the manufacturer’s specifications for dimensions to ensure a proper fit. Using mismatched sizes can lead to leaks and further issues.

Carefully remove the old seals and O-rings. A small flathead screwdriver can help pry them out without damaging the surrounding components. Be cautious to avoid scratching any surfaces, as this can compromise the new seals’ effectiveness.
Before installing the new components, clean the grooves thoroughly. A clean surface ensures a good seal, preventing future leaks. I’ve often found that using a soft cloth and some mild detergent works wonders in removing grime and residue.
Apply a thin layer of lubricant to the new seals and O-rings. This prevents pinching during installation and enhances their longevity. Silicone grease is typically a good choice, but always refer to your specific model requirements.
Position the new seals and O-rings carefully. Ensure they sit flat and are properly aligned. A misalignment can create issues right from the start, so take your time here. Once installed, reassemble the unit and double-check that all components are secure.
After reassembly, test the machine before putting it back to regular use. Look out for any signs of leaking, which could indicate that the seals weren’t seated correctly. If all is well, you’re good to go!
