Are the dishes in the top of the dishwasher coming out wet and dirty? Is the top sprayer not spinning? The most common cause is the feed tube – it’s cracked, broken, or has come loose from its connection. Once the tube fails, water doesn’t reach the top sprayer at all. Result: an upper chamber that won’t clean.

A moment before ordering – safety above all! To ensure a successful repair and maintain the longevity of the device, it is mandatory to use only original parts. Non-original parts may cause damage. Now click the 'Check Model Compatibility' button at the top of the page and our system will immediately confirm that the part is suitable for you.

Why is the top sprinkler not functioning?

The top spray arm is completely attached to the feed tube. The tube is connected at its bottom to the pump opening, and carries water up the entire length of the back of the dishwasher. When it cracks – usually due to wear, being crushed by a dropped dish, or careless removal – the water pressure drops, and the top spray arm does not rotate. Sometimes the tube cracks only at the connection near the spray arm, and you can detect dripping during the cleaning phase.

The hose is made of heat and chlorine resistant gray plastic. However, after many years the plastic dries out and may split. A genuine Whirlpool part is manufactured to exactly the same specifications – same diameter, same flexibility, same connection.

Find the dishwasher's model number on the model sticker - it is located on the inside edge of the door (top or side).

🔧 How do you replace the sprinkler supply hose?

Replacing the hose is a moderately difficult DIY job. The hose is attached at three points along the back of the wall – bottom, middle, and top connection – and all must be loosened. Tools required: Phillips screwdriver and flathead screwdriver.

⚠️ Before any work: Turn off the dishwasher and unplug it.

1. Empty the dishwasher.– Remove the two baskets.
2. Locate the pipe. – It goes up along the back wall, gray in color, connected at three points.
3. Loosen the top connection. – The hose fits into the opening in the dishwasher ceiling with two clips. Use a flathead screwdriver to gently release each clip and maneuver the hose to the left to disconnect.
4. Release the middle connection. – There is a bracket in the body of the pipe that secures it to the wall. Gently loosen it with the flat screwdriver.
5. Loosen the lower connection. – The hose sits in a bottom bracket near the floor. Tilt the hose downward to release.
6. Insert the new pipe. – Connect from bottom to top in reverse order. Make sure each clip clicks into place.
7. Run a short cycle – Check that there are no leaks along all connection points.

💡 Tip from the experts

From the experience of our Whirlpool service technicians, 80% of feed tube breakage occurs due to improper removal of the upper basket. When the basket is pulled with excessive force, the tube is damaged at its upper connection. Each time you remove a basket – lift it slightly and pull it straight. A simple operation that saves repair.

❓ Frequently Asked Questions

Why do the dishes in the upper compartment come out dirty?

The most common cause is a failed supply hose to the top sprinkler. The hose is cracked or disconnected, water is not reaching the spray arm, and the top chamber is not cleaning. Check to see if the top sprinkler is rotating during a cycle – if not, the hose is the likely cause.

Can I replace the pipe myself?

It is possible, but it is a moderately difficult DIY. The pipe is connected at three points along the back of the wall, and each one must be loosened individually with a flat screwdriver. Anyone familiar with plastic work and clip mechanisms will be fine. Anyone who is unsure is better off calling a technician.
