The rotating arm (that sprays water) under the top drinking glass rack keeps falling off. I reattach it by snapping back in place but it eventually falls off again. I don't know the specific part name to order a new one

Hi Ken, thank you for your question. That part would be called your nozzle, part number: PS3527665. You may also need to replace the guide it clips into as well: PS12075961. Good luck with your repair.

The buttons on the select panel only work when the door is about 6 inches away from closed or fully closed. If the door is open any more than this, you cannot select the cycle and no buttons light up.

The dishwasher continues to cycle until the door is open or the breaker is turned off. Do you know what part I would order to fix this problem
For model number LDF7774ST
PartSelect logo
Hello and thank you for writing. Your dishwasher runs on a cycle of cleaning and drying. When the washer will not switch over from one cycle to the next, it may run continuously until you either unplug the unit or open the door of the unit. A dishwasher that continues to cycle may have a bad heating element PS7788065 or control panel PS10066436. We hope this helps. Please contact us anytime if you require further assistance.

Broken door spring allows the door to overextend to the floor if not propped.
Simple, removed screws securing machine in the cabinet, then pull the unit out of the cabinet space about 10 inches. Springs are accessible within this extension. You need strong hands to extend the springs and attach them. Once attached, push machine back in place and re-install the anchor screws. In my situation, only one spring was broken, so the attached side revealed the correct slot to place the hook on the top position, the bottom position has a plastic lead for the spring, and that lead is attached to a rope to the door hinge. Note: Replace BOTH springs, even if only one is broken.

Dishwasher leaking; got AE error almost every other wash
The inside gasket deteriorates over time - However replacement is easy. the main thing you have to remember is after you remove the old gasket, install the new one starting at the middle top of the tub and work your way down both sides. Also, don't push the gasket all the way in...only enough to hold in place. When you close the door the gasket will form a better seal around the door.
