Asko Dishwasher Rinse Aid Notice | Overflow Prevention

Asko dishwasher rinse aid notice — read this important safety alert for full details and affected models.

Overfilling the rinse aid dispenser on Asko dishwashers can cause excessive foaming inside the tub, triggering the AquaSafe flood sensor and leading to a mid-cycle shutdown that leaves dishes wet and undrained. Asko D5000, D5900, and DBI series dispensers hold up to 150 ml, and the fill cap indicator window should never be filled beyond the MAX line.

Concentrated rinse aid that spills into the tub during loading can also leave a chemical residue on glassware and, in rare cases, cause mild irritation if residue contacts food contact surfaces. Using Asko-recommended rinse aid concentrations ensures optimal drying performance without overflow risk.

Warning Signs to Look For

  • Excessive foam visible through the door glass during a wash cycle
  • Dishwasher stops mid-cycle with a water indicator light active
  • Slippery or film residue on glasses and plastic items after drying
  • Rinse aid indicator light activating immediately after a fill
  • Visible rinse aid pooling on the inner door below the dispenser

Prevention Steps

  1. Open the rinse aid dispenser cap (twist counterclockwise) and fill slowly using the indicator window.
  2. Stop filling when the liquid level reaches the MAX line — do not fill to the cap neck.
  3. Wipe any spilled rinse aid from the inner door surface with a damp cloth before closing the door.
  4. Set the rinse aid dosage dial to the manufacturer-recommended setting (typically 3–4 on Asko dispensers) and adjust based on glassware film or streaking.
  5. Use only rinse aid products labeled safe for use in dishwashers — avoid adding liquid dish soap under any circumstances.

When to Call a Technician

If the AquaSafe sensor repeatedly trips without visible flooding, or if the rinse aid dispenser cap no longer seals properly, contact an Asko-authorized technician. A faulty dispenser seal or a malfunctioning foam sensor may require component replacement.
