Important Tips for Asko Models

  • Asko official troubleshooting states water inlet valve diaphragm deterioration causes noise during fill and recommends valve replacement

Foreign objects or debris in sump/filter interfering with pump/impeller rotation

How to Identify: Grinding sound present after fill or continuous through cycle; debris visible in filter or sump when rack removed

Part: Filter/Sump/Pump impeller

Worn or damaged circulation pump impeller/bearings

How to Identify: Grinding continues throughout wash cycles, not just during fill; audible rough, continuous noise rather than intermittent

Part: Circulation Pump/Impeller

Misaligned or obstructed spray arms touching dishes
