Do-It-Yourself Stories from Customers like You Problem with detergent cup lid.   John M. • Craig , CO • November 27, 2017

The foam was shot on the detergent cup lid. Hard as a rock. Causing caking problems, dribble down the inside wall of the door and leaving lumps of detergent. Cut the door in half wit aviation snips and pulled out the two halves. Discovered at this point that the spring had gone soft. Bought one ahead of time, so I was set. Put the spring on the left pin, put the spring pin in the door, slipped the door into place (open) and put the right pin in with pliers. Door snaps open now. Read more

Do-It-Yourself Stories from Customers like You Dishwasher would fill then shut off when restarted it would try to fill again overflowing   Robert J. • Schererville , IN • July 02, 2016

I replaced the float switch. It was an easy enough repair. I didn't have to remove the dishwasher to do the work. The part is accessible from behind the front skirt.The only problem was there is not a lot of space to work in. Getting the fastener off and on requires a stubby nut driver. I used a flexible extension instead. I had to feel for the nut as the bottom of the door blocked my view. A ten minute job and the dishwasher is back in service (for half the cost of my local parts place) While... Read more

Upper Spray Arm/Retainer
Genuine Whirlpool part
By: Whirlpool
Part Number: 12001446

 

Do-It-Yourself Stories from Customers like You Upper spray arm fell off!   Grant I. • Lombard , IL • March 14, 2017

Found the retaining clip on the parts list. Watched the videos to figure out how the upper arm attaches. Tried cleaning out the terribly clogged upper arm. Then looked at the lower wash arm--WOW! Talk about ugly clogs! Watched second video to see how that lower arm comes off. Got the lower arm off and realized all the gunk I was able to poke out of the holes would just come back, so replaced both spray arms. YES, the upper arm includes the retaining clip!! Parts arrived in 1.5 days.... Read more

Do-It-Yourself Stories from Customers like You The metal flanges on the heater element had worn away so that the rubber washer would not fit tight and leaked   Kenneth H. • Morgantown , PA • February 03, 2015

Replaced the heater element, per the video. Also had to connect a new terminal to one of the heater element wires. Once the heater was again connected electrically, the washer completed the entire wash cycle without hesitation. (During the time that the heater element was non-functional, the control "dial" would stop near the bottom, about half way through the cycle, and had to be advanced "one click" manually). The Heater Terminal Shield goes over the Heating Element Nut better if you... Read more
