Why does my top basket need replacing?

The upper basket is one of the most common components to replace in a dishwasher. The plastic threads crack, the movement rollers wear out, and the basket stops sliding smoothly. Sometimes a small blow is enough to break a clip. When this happens – the right solution is to replace it with an original part only.

The full range of all original Whirlpool replacement parts can be found on our website.

The genuine Whirlpool top basket is made of food-grade plastic that can withstand the heat and pressure of washing cycles. Non-genuine replacements may be too stiff, crack, or simply won't stay in place.

Step 3: Gently lift the basket upwards and pull it out completely.
Step 4: Insert the new basket into the same rails. Make sure the wheels are seated on the rails.

💡 Tip from the experts

Tip from Daniel, our service specialist: One of the common causes of squeaking and noise from the upper basket is not breakage but a build-up of mineral residue on the roller tracks. Before deciding to replace – try cleaning the roller tracks with hot water and white vinegar. If the noise continues after cleaning – then it’s time for a new basket.

❓ Frequently Asked Questions

Can I replace the top basket myself?

Yes, absolutely. The top basket is one of the easiest components to replace yourself. No tools required, no power outages, and no complex disassembly. The entire operation takes less than 2 minutes – pull out the old one, put the new one on the same rails.

What might happen if I use a non-original basket?

A non-genuine basket may be one or two millimeters different in size – and cause damage to the spin of the spray arm. In addition, plastic that does not meet Whirlpool standards may warp in heat and cause damage. Genuine is always safer.

Where do you find the model number of the dishwasher?

The model sticker is usually located on the inside door lip, on the left or right side. It includes the model number and serial number. Make sure the model number is listed in the compatible models list before ordering.
