Remove the filter, empty all debris, and rinse the mesh thoroughly under running tap water \u2014 use a hose or pressure sprayer if available, as dried-on debris can be stubborn. If cleaning power is still weak AND the robot flashes a <strong>red LED<\/strong>, the pump motor impeller may be stalled by trapped debris. Consult the manual for impeller access and inspection. If the filter is clean and there is no red LED, the pump motor itself may have a fault requiring after-sales service.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-steps\"><\/div>\n        <h2>Step 1: Deep-Clean the Filter Basket<\/h2>\n        <p>Remove the filter basket from the robot. Empty all visible debris. Rinse under <strong>running tap water<\/strong>, using your fingers to rub the mesh gently and dislodge trapped particles. For filters that have not been cleaned in several cycles, dried-on debris can clog the mesh \u2014 use a garden hose with a spray nozzle for stronger flushing. Do not use soap, detergent, or solvents. Allow the filter to <strong>air-dry completely<\/strong> before reinserting. A wet or damp filter restricts airflow and reduces suction noticeably.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-warn\"><\/div>\n        <h2>Step 2: Check for Red LED \u2014 Pump Motor Stall<\/h2>\n        <p>If the robot flashes a <strong>red LED<\/strong> while operating, this indicates a motor fault \u2014 most commonly a <strong>stalled pump impeller<\/strong>. Turn off the robot, remove the filter, and inspect the impeller area (refer to the user manual for the exact access procedure on the S3). Look for hair, string, leaves, or small stones jammed in the impeller blades. Carefully remove any debris with tweezers \u2014 do not use metal tools that could damage the impeller. Reassemble and test. If the red LED persists after clearing the impeller, the pump motor itself may be damaged.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-fix\"><\/div>\n        <h2>Step 3: When It&#8217;s a Pump Motor Fault<\/h2>\n        <p>If the filter is clean, the impeller is clear, and there is no red LED, but suction remains weak, the <strong>pump motor<\/strong> may have an internal fault (internal wear or electrical failure).
