Safety first: No special electrical safety concerns for this issue, but avoid inhaling cleaning chemicals.

• Refill dishwasher salt: If your Ikea model has a salt reservoir, fill it with dishwasher salt and adjust the water hardness setting according to your local water hardness.
• Use rinse aid: Ensure the rinse aid dispenser is filled and dosage is adequate.
• Run descaling cycle: Use a dishwasher cleaner or citric acid on a hot program to remove internal scale.

Persistent heavy scaling may require repeated cleaning cycles. No parts usually need replacement unless the water softener valve is defective.
