Ascending water tube

Technicians typically replace this part when they’re seeing poor distribution, visible wear, cracking, or a component that won’t stay seated. After replacement, run at least one full cycle and recheck for leaks, vibration noise, or fasteners that loosen during operation. Part 1864500302 corresponds to Ascending Water Tube and is commonly sourced for ice maker repairs. Tubes and connectors route water or drain flow. Splits, kinks, or loose connections lead to leaks or restricted distribution. A short post-repair check—visual inspection plus a full cycle—helps confirm the issue is resolved and nothing else is stressed. A correct-fit replacement can prevent small issues from turning into bigger failures. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. If the part interacts with water, do a leak check during the first run and again after a short operating period.
