How to Troubleshoot & Replace Ge AP4980655 / WD22X10081 Upper Spray Asm

Got a replacement part, screwed it in, and now no spray arm falling off during cycles. 

New part from AppliancePartsPros.com. 

All parts arrived as ordered and much faster than I anticipated. The silverware basket and upper spray arm were quick replacements with no tools needed. The old lower dishrack rollers required pliers to remove, but no tools were required to install the replacements. The AppliancePartsPros.com repair videos were helpful. With the dishwasher repairs completed, our household entered a new era of peace and prosperity. :) 

Simple fix only took me less than 1 minute to take off and install the new part. Thanks!! 

Replaced both the roller and spray arm when they arrived. Took about 2 minutes and has the dishwasher working like new again. Next purchase might be the bottom rack to replace the original, which is getting rustier by the day. 

Replaced the whole assembly since I couldn't find just the gasket on the site. 

Super easy, just turn knob on replacement until it locks. 

Ordered a new one and snapped it on in 2 minutes. 

Easy install. Works like a charm. 

Attached a new Upper Spray Arm onto the upper Arm.
