Frigidaire does not work display blinking

[SIZE=3]Hello,[/SIZE]
[SIZE=3][/SIZE]
[SIZE=3]Frigidaire dishwasher is 2 years old and stopped working. The display is blinking and shows "Er", "Washing", "clean" Drying" (all dipaly parameters). When door is closed, the dishwasher starts draining continuously eventhough there is no water.[/SIZE]

[SIZE=3]When I cycle the power the display shows PF, but reverts to blinking display as soon as door is closed and open.[/SIZE]

[SIZE=3]Is the controller bad? [/SIZE]
