Why does my Smeg CWG420D Dishwasher have poor washing results?
- PpdunnAug 12, 2025
Poor washing results with your Smeg Dishwasher can stem from several issues. Start by checking if the spray arm washing holes and nozzles are blocked by dirt or limescale, and clean them if necessary. Ensure the filter isn't fouled. Verify you're using the correct type and amount of detergent and rinse aid. Also, make sure plates and glasses are arranged correctly. If the water temperature is low, contact After-Sales Service. Select a longer washing cycle for very dirty dishes. If detergent or rinse aid isn't being supplied, a worn or broken pipe inside the peristaltic pump may need replacement by the After-Sales Service.
