For model number LDFN4542B

Hi Phil, Thank you for your question. The AE error code indicates that there is a leak inside the dishwasher possibly from the water inlet valve, the hoses, or the door seal. You will need to inspect these parts to see which one is causing the issue. We hope this helps!

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.

Second roller in on the left side was missing don't ask my how, pulling the bottom rack out the rack would dip down i had to lift it up to pull it the rest of the way out.
Ordered the roller from Parts Select, slid the roller over the little spindle sticking out of the bottom rack and snapped it in place. Job done in less than one minute.
