How to Troubleshoot & Replace Bosch AP2802425 / 00359975 Dishwasher Lower Spray Arm

The wash arms and filters were plugged with calcium and no longer spraying. Needless to say this impacts cleaning. The replacement parts were top quality and fit perfect. This simple replacement of parts put new life in trusty Bosch. 

I researched the internet on the symptom, and AppliancePartsPros.com advised the most common problem was the Circulation Pump...seals and broken impeller. It was only by watching AppliancePartsPros.com's repair video, that I was able to accomplish the actual fix. It took about an hour to get to the old circulation pump, and once I had it apart, it was quite obvious the impeller and the bushing seals were toasted. I replaced all the circulation pump parts, replaced the water inlet valve for good measure, and the lower spray arm for as my original was cracked, and the unit is now performing just like it did when we purchased it 10 years ago. 

Went on the internet, found Appliance parts right away, had my parts delivered via Fedex in only a few days (in Hawaii!) for a whole lot less money than buying a new dishwasher, which I thought I needed. Easy assembly--that's the Bosch part. 

Replaced door seal and gasket, replaced water feed tube to upper rack and lower spray arm. 

Followed the manual. It took five minutes. I ordered the parts. It seemed like five minutes later the doorbell rang and three packages were at the door. (It took less than 24 hours from order to delivery, and we live on a rural island in the middle of Currituck Sound, NC. Kudos to the shipping and logistics folks. Overall a great experience. 

Watched the video. Repair took less than 1 minute. Also replaced basket assembly and both spray arms. Total repair time for all was less than 5 minutes. Thanks for the videos on each repair part 

Ordered replacement parts watched your video and it’s fixed 

Buying new spray arms made all the difference in the world to getting our cleaning power back again in the dishwasher. It took less than two minutes to install. So simple! 

Replaced filter and moving blades then used CLR to reduce remaining build up. 

The Bosch dishwasher that came with the house needed a new filter assembly and soap dispenser door. While I was online ordering those necessary parts I also purchased two new spinning arms for the lower and upper since those both appeared to be partially clogged with hard water build up. I watched the video for the soap door just to make sure I put the spring back on in the right direction, the other parts just pop right into place, no tools needed at all for this repair. Easy peasy. Dishwasher works great again. Amazing what proper water spray and filtration will do.
