HDA3520Z07BB Hotpoint Dishwasher - Instructions

I removed 2 screws a wire plug connector and replaced the old part. The total repair including putting the cover plate back on only took about 15 minutes. Also I saved approximately $130.00 by doing this repair my self.

I connected one end of hose to the drain using a hose clamp and screwdriver then connected the other end to the dishwasher using anouther hose clamp and a screwdriver..

Removed the 4 screws on front inspection plate and had easy access to solenoid switch. Unplugged unit and switched out with repair kit. So easy a caveman could do it...

from the information previous customers had written.
it saved a lot of fustration and time
and best of all the dish washer does not leak.

Used Phillips screwdriver to undo brackets that keep dishwasher in place. Pulled out dishwasher from underneath the counter. Placed hinge arm in spring, hooked spring onto clip, placed hinge arm in clip. Put back dishwasher under the counter and screwed in place. Took all of 15 minutes. Saved 185.00 for service call.

took out 4 screws pulled piston out and changed put back together. very easy and inexpensive!! thanks

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

Removed the 4 screws holding the filter screen assembly in the back of the tub. This exposed the Piston and Nut assembly which unscrewed fairly easily.
Replaced with the new part, put the filter screen assembly back in place ran the machine. The machine still stops with the blocked arm message - just not as frequently. The web researched fix with the piston and nut assembly replacement was obviously not the final answer. I am now out of options I believe except to bite the bullet and get a new machine. Any other suggestions are welcomed.

Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

remove the screen at the back bottom of dishwaser. (4 screws). Unthread piston and and nut assembly for check valve....thread in new one.
Problem solved....no more water $10 part....no repair person !!!

Followed the simple instructions to unscrew the old unit and replace with the new one. The unit was easily located on a diagram on the internet and the website instructions for removal were spot on.

A no brainer, replaced old fill cap with new fill cap. Delighted I was able to order the part, website is user friendly.

As per instructions from this site I simply unscrewed the entire assembly and installed the new spray arm assembly. The old unit was a bit stubborn due to age so I used the long handle of my favorite screwdriver, inserted through the bottom area, for leverage. The entire process took less than 5 minutes. Very simple and as a side benefit, the dishwasher operates much quieter than before the old spray arm broke. Guess the old arm was also worn out before it broke on this 18 year dishwasher.

First I removed the bottom dishwasher rack. Using a 1/4" nutdriver I removed (4) 1/4" screws from the drain cover that is inside the dishwasher all the way in the back. This will allow you to get to the piston and nut assembly which was easily removed with no tools by simply grasping and unscrewing. Used a wash cloth to wipe "gunk" from around the threads. I then screwed the new piston and nut assembly in place. Used no tools to tighten, just "snug up" by hand. The seal on my old piston and nut assembly was 50 percent gone, not sealing at all. I guess the years had taken their toll. This solved my problem. The dishwasher washes and drains as it should. Super easy fix. Took me about 10 minutes to do the repair.

Unscrewed bottom of spray arm support assembly counterclockwise by hand for removal. Inserted new part and screwed it in clockwise by hand for installation. Worked perfectly. Video was helpful.
