I have a Kitchen Aid Dishwasher with a problem. Need to remove the lower spray arm hub but cannot see how to accomplish. Need info on removal internal rear feed cap. Appears to need to be unclipped and then twisted 90 Degrees. What else has to be removed to do this.
Please hurry as wife is getting edgy!

Thanks
Keith

You have to remove the upper dish rack and the feed tube assembly (#1 on the [B]diagram[/B]) and disconnect it from the rear feed cap first. Holding the lower spray arm with one hand turn the hub CCW to release the lower spray arm. Turn the rear feed cap for about 90° to release it.

Here are the breakdown diagrams and replacement parts for the Kitchen Aid dishwasher [MODEL]KUDM01TJWH0[/MODEL]
