Overview
- This week multiple outlets reported that lab tests and household experts confirm Eco cycles clean well for light soiling but often fail on baked‑on or strongly dried food.
- Household expert Yvonne Willicks and FH Münster’s tests show low temperatures let fat, starch and protein residues remain in narrow hoses, the pump sump and spray arms where buildup can form biofilm and strain the motor.
- Experts now recommend running a 60–70 °C intensive cycle about once a week to flush pipes and pump areas and reduce the risk of blockages and repairs.
- Consumers should clean the filter and remove and clear spray‑arm holes at least monthly, adjust water‑softening to local hardness, and prefer powder detergent so dosing matches load size.
- The Eco program remains required on new machines since 2021 and saves roughly 10 liters of water and under 1 kWh per cycle, so occasional hot cycles and basic upkeep let users keep efficiency benefits while protecting appliance life.
