SHP878WD5N/11 Bosch Dishwasher - Instructions

1) Remove the three torx screws securing the handle.

2) Open door. Placing some cushions under the door makes the operation easier.

3) Remove the 12 torx screws securing the door skin. Note the screws are of two sizes. The lower 6 are shorter and fatter than the upper 6, that also secure the control panel.

4) It’s useful to have a 2nd person or a counterweight to secure the door once the skin is removed.

5) Remove the old handle by snapping the securing tabs.

6) New handle is press to fit.

7) Return skin to door and re-insert screws to secure.

8) Re-insert the three handle screws.

Notes

1) A three red wire cable plug was floating in the breeze when i removed the skin. I assumed it had pulled loose during removal of the skin so inserted back into the control panel but the washer would not power up with it inserted. On removal it worked fine. Not sure it it serves a model specific function.

2) It may be possible to use a car trim pry tool to remove the handle but I was concerned the stainless might be distorted.

Removed the middle basket and turned it upside down. Unplugged the spray arm from the middle basket. Snapped the new spray arm into the middle basket.
Installed middle basket into slides.
It works great. Great site for parts - reasonable prices too

Determined that the unloader valve was leaking.
Removed the unloader valve from valve body.
I could see a crack in the nylon portion of the valve. This would not let the relief valve operate.
Went to the internet (Part Select) and found the replacement valve. There are a lot of different sizes of unloader valve. Partselect help me select the correct valve.
The key was the valve body, the unloader valve inserts into the valve body. There are two types of valve bodies, a 4 bolt and a 5 bolt. They look the same but do not interchange. I needed the 4 bolt.
I was nervous as the new unloader valve was a different construction than my old valve. It worked perfectly.
Replacement was easy.
Locate the unloader valve. It is part of the pump body. You can recognize it by the spring extending out from the valve body.
Remove the “U” shaped clip that holds the unloader valve in the valve body.
I used pliers to grab the spring and pulled the unloader valve from the valve body. It took a little pulling pressure to remove.
Note the orientation of the unloader valve I. The valve body. You want to install the unloader valve with the same orientation.
It may take a little force to seat the valve. I used a little silicone grease to lube the valve. A small tap on the end of the valve to insure it is fully seated.
It has to be seated so the “U” shaped retaining clip can be inserted to hold the unloader valve in place. Again, a light tap was necessary to fully seat the clip.
That was it, I was back operating my pressure washer

The wheel easily snapped in.
