  • Reduces slamming or sudden drop when opening
  • Common failure signs: door feels heavy, drops quickly, opens unevenly, or a spring is visibly broken
What's included: 1 door spring Install notes:
  • Disconnect power and shut off water; remove the toe-kick/access panel
  • Support the door; note spring routing and which frame holes are used before removal
  • Install the new spring in the same holes; adjust hole selection only per service information to fine-tune tension
  • Springs are under tension—wear gloves/eye protection; consider replacing both springs together for balanced operation

Do-It-Yourself Stories from Customers like You Flappers on docking station were worn out and/or missing also the pump filter fabric was torn so a new pump filter was installed as well   Gregory P. • Mansfield , OH • January 01, 2017

Dishes were 'gritty' with an almost invisible coating of specks smaller than grains of salt. Prior to ordering parts, I had to determine which part(s) needed replaced and which could benefit from a good cleaning. After viewing Appliance Parts Pros YouTube Videos, I removed the Main Manifold (snaps right off) including the Top Spray Arm. I discovered the Flappers of the Docking Station (AP6009888) were worn out and/or missing. I removed the Docking Station simply by popping the old one off... Read more

Do-It-Yourself Stories from Customers like You Dishwasher started making a grinding noise   Timothy T. • Alpharetta , GA • June 26, 2015

Searched the dishwasher model on ApplianceParts (had used them for a washing machine repair a few years earlier). Was looking for an exploded diagram of the internal parts so I could figure out what might be the problem. There was a video for a motor seal repair kit that seemed to address the bearings which is what I suspected was the culprit. The video started by noting that "you want to replace the motor seal if 1) you have a leak or 2) your dishwasher is making a noise". I watched the... Read more

Spun each of the three wash arms by hand. All could be made to touch/scrape but the top one was super wabbly. Ordered both the arm and clip. Repair took less than a minute.

Do-It-Yourself Stories from Customers like You Rinse agent reservoir was leaking unit wouldn't hold liquid… just ran out as you filled it   Morgan L. • Cumming , GA • August 19, 2014

Ordered the part. Arrived the next day. Took the eleven screws off the door exposing the back of the Soap/Rinse Aid dispenser. Six screws hold it on the inside of the door. Popped off easily. There is a plug that runs from the timer to the dispenser…it's a pain to get off. Use a flat head screw driver. Screwed the new unit in place. Plugged it in. Put the door back together. I accidentally caught the door catch in the door and screwed it together seizing it...so I had to take the top screws off... Read more

Do-It-Yourself Stories from Customers like You Rollers failed on middle rack (plastic shafts broke)   Russell W. • Chesterfield , MO • November 14, 2015

Replaced rack adjuster assembly on both sides. Easy repair, and the parts arrived within 2 days. Replacement parts appear to be better designed to prevent the roller shafts from failing. Hint: The rollers on the top rack seem to be the same. I removed and saved the rollers and shafts from the old parts in the event I have to replace those on the top rack someday. Read more
