Error code on a Frigidaire Dishwasher (Gallery Series)

[G-Man929]

Model Number: LGHD2433KM0
Brand: Frigidaire
Age: 1-5 years

When I press the "Normal Wash" button on my dishwasher, it lights up like it would normally do. When I press the start button, the light (mode) changes to "Top Rack" and I can hear water coming in. It won't let me cancel the cycle when this happens. After a minute or two, there is an error code that comes on the screen in which the "Washing and Drying" lights are on, on the left hand side of the display, there is an "Er" in the middle, and the "Clean and S" lights are on, on the right hand side. Also, the "Add Rinse Aid" light comes on, but the reservoir is full.

Any help is appreciated..... Thanks!
