⚙️ Understanding the Mechanics

Inlet filters act as the primary defense against sand, rust, and scale present in the water supply. These particles clog the fine mesh over time, causing the machine to throw 'Low Pressure' errors or take too long to fill.

Cleaning these filters every three months ensures the internal solenoid valves do not get stuck open. A Specialist checks both the tap-end and the machine-end filters to ensure maximum flow for the Project.

🔍 Flow Issues Diagnosis

Symptom	Cause / Fix
Machine hums but no water enters	Filter is completely blocked by debris
Water trickles very slowly into drum	Partial blockage or low Agency supply pressure
Error code PE or IE on display	Inlet timeout due to restricted water flow

❓ Common Blockage Sources

Fine sand or silt from underground storage tanks
Rust flakes from old galvanized iron supply pipes
Calcium carbonate scale buildup from hard water sources

⭐ Specialist Maintenance Tips

💡Check the tap-end of the hose as some hoses have a second filter there

💡Soak stubborn scale-covered filters in white vinegar for 10 minutes

💡Always inspect the rubber washer inside the hose nut for cracks before reconnecting

🔄 Other Fixes to Try

External Sediment Filter — Install a clear pre-filter housing on the tap if the Client has very sandy water

Hose Replacement — Replace the entire inlet pipe if the internal rubber is collapsing

⚠️ Common Errors

Using a screwdriver to pry the filter which tears the delicate mesh

Forgetting to turn the water back on before testing the machine

Cross-Threading Risk

Always start screwing the plastic nut by hand. If it feels tight immediately, unscrew and try again to avoid ruining the plastic threads.
