Classeq dishwasher chemical dosing seems inconsistent; sometimes too much, sometimes too little detergent.

Safety first: Wear appropriate PPE when handling chemicals. Isolate power before servicing pumps.

• Inspect pump tube: On peristaltic detergent and rinse aid pumps, check the flexible tube for flattening, cracks, or hardness. Replace if worn.
• Eliminate air leaks: Ensure suction tubes are fully submerged and connections are tight. Replace brittle tubing.
• Clean injectors: Remove and clean chemical injectors and non‑return valves to ensure free flow.
• Recalibrate dosing: Using Classeq's procedure, set and verify dosing times to achieve the correct concentration.
