Hard water buildup in the tub.
• Remove all dishes, silverware and silverware holder from dishwasher. Only
racks should remain in tub. For best results, use citric acid powder (can
be found in canning sections of most grocery stores or online). Measure 3
tablespoons (40 g) of citric acid powder. Fill main wash compartment with
measured powder. If you cannot find citric acid powder, pour approximately
one cup (200-300 mL) of white vinegar into shallow bowl and place in upper
rack. Run Machine Clean cycle. Do not use detergent.
