Dispenser Arm for Frigidaire Dishwasher

thingiverse

The detergent dispenser door on our Frigidaire Dishwasher stopped opening during a wash. I also noticed that there wasn't a decent spring back on the dispenser door lock when you manually cycled it. It turns out the arm which captures the spring and is activated by the detergent dispenser door solenoid had worn out. The only replacement part they sell is the entire detergent dispenser door, which is $30 and several days shipping (part # 5304507354). I gave myself 4 hours to design, print, and test a new one before I would let myself order it. :) Seems to work in static tests, just assembled everything and running a test wash now. This arm also controls the rinse aid dispenser, so hopefully everything still activates as it should. A full write up is at: https://1projectaweek.com/blog/2017/7/20/practical-3d-printing
