There are several reasons for your metal kitchenware and utensils to rust. Please see if one of the following will solve the problem.

Make sure to open the door after the cycle finishes

Moisture is the number-one cause of rust. The air inside your dishwasher is humid after a wash cycle.

To avoid this moisture settling on your dishes, open your dishwasher’s door once the cycle has finished and leave it slightly open for a while. This will allow the humid air inside the appliance to escape and prevent your metal cutlery or kitchenware from rusting.

Avoid washing low-quality or non-dishwasher-safe kitchenware 

Not all metals are dishwasher safe. In addition, low-quality metal or metal coated items are prone to rusting if washed in the dishwasher. Check the manufacturer’s instructions of such items to see if they’re dishwasher safe. When in doubt, avoid washing these items in the dishwasher.

Avoid using metal utensils for unintended purposes

The protective cover on metal utensils such as knives may become damaged if they’re used for anything other than their intended purpose. Don’t use them to open cans, loosen screws, etc.

Avoid washing already corroded items

Rust can spread between metal utensils. To protect your other metal ware, don’t put rusty items in the dishwasher. 

Make sure to scrape off the food remains on dishes

Traces of food left on metal items may cause corrosion over time. Soiled items shouldn’t be left waiting in the appliance. Wipe away food remains before putting metal items in the dishwasher or load them just before running the appliance to avoid rust. 

Make sure the water hardness setting is appropriate

If your tap water is rich in heavy metal ions, this can cause or accelerate rusting. Your dishwasher has an internal water softener unit which reduces the hardness of the tap water and neutralizes these metal ions. This unit works best when complemented with dishwasher salt.

Beko dishwashers with Auto GlassShield® have sensors which determine the hardness of your tap water and adjust the water hardness setting automatically.

Avoid spilling dishwasher salt inside the appliance

Dishwasher salt helps your appliance’s internal softener unit reduce the hardness of the tap water. However, it has a corrosive effect on metal surfaces.

Dishwasher salt reservoirs contain water, and this water may overflow when you fill the reservoir with salt. Salt may also spill inside the appliance while refilling the salt reservoir. Salt inside the dishwasher tub may scratch glassware.

To minimize salt spills, use the funnel provided with your Beko dishwasher when pouring salt into the reservoir, and be sure to wipe away any overflowing water or salt granules. Close the reservoir lid tightly after refilling it.

Run a prewash programme or the shortest programme to wash away any salt that may have been spilled inside the appliance. Salt granules under the lid will dissolve during prewash and may cause the lid to loosen. Check the lid at the end of the programme and close it firmly.

Avoid using inappropriate detergent and other products

Be sure to use detergents, rinse aid and salt which are specifically for dishwashers. Don’t use dish washing liquid, hand soap, bleach, vinegar or any other chemicals under any circumstances as these products reduce your dishwasher’s performance, cause metal pieces to rust, and may even shorten the lifespan of your appliance.

Make sure the appliance is loaded properly

You may be loading your dishes incorrectly or overloading your dishwasher. Make sure all your dishes are tilted properly and that they’re not touching each other. See that stainless steel, silver-plated and copper items aren’t in contact with each other. The chemical reaction with hot water and detergent can cause discolouration of these materials.

Make sure the outlet that the appliance is plugged in to is grounded 

Your dishwasher needs to be connected to a properly grounded outlet. Ungrounded outlets will cause static electricity build-up inside your dishwasher. Static electricity erodes the protective layer of metal objects and can cause them to discolour of form pores.
