A spotless clean is what you expect from your Zanussi dishwasher—but what if your dishes come out with cloudy residue or visible spots? You’re not alone.

1. Hard Water Mineral Deposits

What Happens: Minerals like calcium and magnesium in hard water can leave white, chalky spots on dishes and glasses.

Simple Fix:

• Use a rinse aid regularly to break down mineral buildup.

• Consider installing a water softener if hard water is a persistent problem.

• Clean your dishwasher monthly with a descaler or vinegar rinse.

2. Insufficient Rinse Aid

What Happens: Without enough rinse aid, water doesn’t sheet off dishes properly, leaving behind droplets that dry into spots.

Simple Fix:

• Check and refill the rinse aid dispenser.

• Adjust the dispenser settings to release more rinse aid during each cycle if needed.

3. Overloading the Dishwasher

What Happens: Overcrowding blocks water and detergent from reaching all surfaces, leading to spotty or unclean dishes.

Simple Fix:

• Load dishes with enough space between them.

• Avoid stacking or nesting cups and bowls.

• Make sure the spray arms can spin freely.

4. Low-Quality Detergents

What Happens: Poor-quality or expired detergents may not break down food residue and minerals effectively.

Simple Fix:

• Use high-quality dishwasher detergent recommended for Zanussi appliances.

• Store detergent in a cool, dry place to maintain its effectiveness.

5. Dirty or Clogged Spray Arms

What Happens: Spray arms clogged with food debris or mineral scale can’t distribute water evenly.

Simple Fix:

• Remove and clean the spray arms using warm water and a soft brush.

• Ensure the holes are clear of debris and rotate freely.

6. Incorrect Cycle Selection

What Happens: Using a light or eco cycle for heavily soiled dishes can result in incomplete rinsing.

Simple Fix:

• Match the wash cycle to the load type and soil level.

• Use the intensive or heavy cycle for tough cleaning tasks.
