Common Problems & Solutions

Many dishwasher problems have easy solutions that don’t require a visit from a technician. 

Dishes still wet

  • Load dishes correctly so that the water can run off freely.
  • Regularly add Finish® Jet Dry® to the rinse aid dispenser.
  • Increase the setting of rinse aid dosage, if necessary.
  • Possible faulty heating element. (Contact a technician.)

General poor cleaning

  • Avoid low quality and old/damp detergent.
  • Dose detergent as recommended.
  • Load and sort dishes to allow water to circulate.
  • Use Finish® Dishwasher Cleaner to remove limescale and grease build-up.

Food around filter

  • Remove and clean filter.
  • Scrape off large food particles from the dishes before loading.
  • Use normal and auto wash cycle.
  • Use Finish® Dishwasher Cleaner to keep this vital component working properly.

Cloudy glassware

  • In hard water areas, avoid limescale deposits by adding Finish® Power Up™ to each cycle.
  • Determine your local water hardness and adjust the rinse aid setting accordingly.
  • White streaks on glasses could be surface corrosion. See vinegar test.
  • Avoid this by using low temperature or china/crystal cycles. Use Finish® Quantum® with built-in anti-corrosion protection.

Rusted cutlery

  • Avoid prolonged contact with acidic/salty food (e.g., mustard or ketchup).
  • Use high-grade quality stainless steel. (e.g. 18/10)

Faded patterns on plates

  • Use Finish® Quantum® with built-in anti-corrosion protection.
  • Run low temperature cycle, or if dinnerware is not dishwasher-safe, wash items by hand.

Detergent residues at end of cycle

  • Check door of dosing chamber is not blocked by bulky dishes or large utensils.
  • A damp dosing chamber can cause tablets and powder to stick.

Spots, drops marks, and smears on glasses

  • Load dishes correctly so wash water runs off freely.
  • Regularly add Finish® Jet Dry® to the rinse aid dispenser.
  • Use Finish® Power Up™ in each load.
  • Determine your local water hardness and adjust the machine setting accordingly.

Foaming machine

  • Traces of hand dish soap on dishes. Pre-washing is not necessary with a high quality detergent like Finish® Quantum® or Finish® All-in-1 Powerball® Tabs.
  • Rinse aid spilled during refilling, or rinse aid chamber could be leaking.
  • High amount of protein-based food left on dishes (e.g. egg, milk).

Orange staining on plastics

  • Possibly caused by red sauce in the wash such as spaghetti sauce.
  • Scrape items before loading or use a rinse and hold cycle.
  • Bleach back to original color by placing in strong sunlight.

Dishwasher not draining

  • If the drain hose is kinked, the water cannot run properly into the machine. Make sure that a portion of the drain hose is at least 0.5m above the dishwasher’s enclosure floor.
  • Avoid a clogging of the filter system by cleaning regularly (e.g. once a week). 
  • The kitchen sink drain may be clogged and it may be necessary to ask a plumbing service to remove the blockage.

Odor

  • Food stuck in build up on the side of the machine or a dirty filter often cause odor coming from the machine.
  • Clean filter and use Finish® Dishwasher Cleaner.
