I bought a new upper diswasher rack from your company but can not remove the caps on the upper rail. How do I remove them. and if I order new ones do they come singlely or a pair.

You need to get a flat head screwdriver or something sililar, I use a key. pry the back piece back far enoughso it's even with the indent on the rail and twist it out.

Jona's suggestion on removing end caps absolutely works. I'd spent half an hour trying to figure out how to get end caps off to replace roller wheels. Within 5 minutes of reading the post, I was finished. This information saved me at least $65.

thanks a lot Jona! very clear and simple explanation

of course now that i replaced the upper rack, that little 'water tower' thing doesn't quite fit and is about 1/2" too tall .. will not having that affect how well it cleans?

How to get off the end caps off my ten-year old GE dishwasher rack was a tough puzzle to me as well, but the above suggestion made the process a lot easier. . I don’t know if my end caps are precisely the same as those described above, but there are similar steps. The secret to their removal was the discovery that the face of the end cap consists of two surfaces that lock together when installed. The end piece, after removal, has an upside down “V”-shape when viewed from the top. The front face of the end cap is attached to one leg of the upside-down V, while the back surface of the end cap is attached to the other leg of the “V”. When viewed from the front, the back surface of the left-side cap is shaped like the letter “C”, while the leg of the front surface is shaped like an elongated “O.” Picture a letter “C” whose font size is about twice as tall as that for the letter “O.” If sized properly, and if the letter “O” is to the right of the letter “C”, the letter “O” can be snapped into the body of the letter “C” by opening up the ends of the letter “C”. To remove the end cap, one must pry apart the legs of the upside-down “V” as viewed from the top while facing the dishwasher. Once the “V” is opened up, the tongue that protrudes into stainless steel runner will withdraw, and the end cap can be slid off. To open the “V” without marring the appearance of the end cap, do as in the prior post. Pry the “V” open by inserting a small blade screwdriver between the plastic end cap and the top of the stainless rail. Once done, the front face will partially separate from the rear face, and a blade screw driver can be used to pry to “O’ shaped leg out from the “C” shaped clamp.
