Dishes were 'gritty' with an almost invisible coating of specks smaller than grains of salt.

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

First, I checked the Appliance Parts Pros website and learned how to do a reset (unplug, wait, plug back in). That restored some functions, but not all. After further reading about people who had resolved similar problems, I decided to order and replace both the electronic control board and the control panel.

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
