FREQUENTLY ASKED QUESTIONS ABOUT HÄFELE DISHWASHERS
1. Common Questions
1.1 Do dishwashers consume a lot of water and electricity? No. A single wash cycle uses only 9–12 liters of water, which is more efficient than hand washing (20–30 liters). Power consumption averages 1–1.5 kWh per cycle, depending on the mode.
1.2 What are the main washing modes?
Quick (30–45 minutes): For lightly soiled dishes
Eco: Saves water and electricity, takes longer (~2 hours)
Intensive: For pots, pans, and heavily greased dishes
Glass: For glassware with gentle water pressure
Rinse: Pre-rinse only, no detergent used
1.3 Are dishwasher salt and rinse aid necessary? Yes. They help soften water, prevent limescale buildup, and keep dishes shiny and durable.
1.4 Should dishes be rinsed before placing them in the machine? No need to wash. Just scrape off large food residues to prevent filter blockage.
1.5 What types of items can be washed? Suitable: Stainless steel, glass, ceramics, and stainless-steel cutlery Not recommended: Wooden items, cheap non-stick pans, and non-heat-resistant plastic
1.6 Can plastic items be washed? Only if they are labeled “Dishwasher Safe” or heat-resistant to ≥ 70°C.
1.7 When should the filter be replaced? Every 12–24 months or if it is cracked or deformed.
1.8 Can regular dishwashing liquid be used? No. Only use dishwasher tablets or specialized powder to avoid excessive suds that could cause overflow.
1.9 Do dishwashers dry the dishes? Most Häfele models include heat drying and auto door opening for faster drying.
1.10 Can I wash a small load of dishes? Yes. The Half Load mode helps save energy and water when washing fewer items.
2. Safety Notes
2.1 Electrical Safety
Use a dedicated circuit breaker (16–20A); don’t share with other high-powered appliances
Power cords must meet safety standards and avoid contact with water or heat
Disconnect power immediately if you notice a burning smell, strange noise, or water leakage
2.2 Operating Safety
Do not open the door during operation (hot water pressure). Pause the machine first if necessary
Keep children away from the control panel and operating area
Sharp utensils should be placed flat to avoid blocking the spray arms
2.3 Installation & Spacing
Keep at least 5–10 cm of space from the wall to prevent kinks in the drain hose
Place the machine on a flat surface to ensure proper drainage and pump function
