Product Description

CONDUIT MID BLASTER Assembly Specifications

This middle conduit assembly, also known as the middle spray arm water supply tube, is an authentic OEM replacement part designed for dishwashers. It is a gray, plastic tube that connects the main water supply line to the middle spray arm. The conduit ensures that sufficient water is released for thorough and efficient cleaning while the dishwasher is running. If the conduit assembly is damaged or faulty, there will be little to no water released during the wash cycle and you may also notice water leaking from the dishwasher. It is important to replace this part promptly to ensure the efficient running of your dishwasher.

The sprayer keeps falling down- it comes off and falls down. I don’t know if I need both the assembly and the paddle
For model number GDP645SYN3FS

Hi Kyle, thank you for your inquiry. First, you will need to check the connection clips on the assembly. If there is an issue with the connection clips, then you will need both the conduit mid-blaster assembly, part number PS11729194, and the middle spray arm, part number PS16542477. We hope this solves your problem!

Bottom spray doesn’t move during wash and powder doesn’t dissolve. Some dishes clean others not. Had this problem before quite recently (march) and repairman said diverter valve was blocked with string. No idea how that got in there. Cleaned it out and all well until now. Have checked arms move and no holes blocked. So do I need a new diverter valve and can we install ourselves, don’t want to spend another $255 on a machine that’s only a few years old

Hello Maggie, thank you for reaching out. If the spray arms are not moving and the dishes are not being cleaned, we would recommend replacing the diverter assembly, part number PS16217028, to fix the issue. It controls the flow of water to the spray arms. You can easily replace this part by using the following instructions: 1. Turn off the dishwasher. 2. Remove the upper and bottom rack assemblies. 3. Remove the lower spray arm. 4. Press the tab and twist counterclockwise to release the diverter assembly. 5. Remove the diverter assembly and replace it with a new one. We hope this information helps!

Does this part often need to be replaced to seal and spray well? Just replaced my pump but top an bottom arms still don't spin. My sprayer looks fine but my arms don't spin or clean well.

Hi Eric, Thank you for your question. If the conduit is clogged with residue or mineral build up, water may not flow to the spray arms. Try giving it a good cleaning. Shake some baking soda on the bottom of the dishwasher and add some vinegar. Use a hot water cycle and see if this will clean the conduit. If this does not help, it may be damaged or faulty and it will need to be replaced. We hope this helps!

My GE dishwasher is not cleaning dishes well on the top rack. I replaced the diverter, which definitely now send the water up to the top spinner under the rack. What I notice is part number 618 on the guide does not spin as well as the bottom one does. I’m wondering what needs to be replaced to make that piece spin correctly. Does 632 need replacing?

Hello Dan, thank you for contacting us. We would recommend checking the spray arm for any dirt or debris first. If it is fine, then you may need to check the conduit assembly, part number PS11729194, which is listed as 632 in the diagram, to solve the problem. We hope this helps!
