The Problem: There is a membrane switch failure, meaning one of the keys is throwing the wrong signal. This error can also be caused by a stuck key or a key pressed for longer than one minute.
The Fix: Check the keys on the control panel and the wiring between the keypad and main control board. If you cannot identify and fix the issue, replace the keypad. If the error persists, replacing the main control board should fix the issue.
Based on the symptoms you described, it's likely that there is an issue with the heating element or thermostat in your Frigidaire dishwasher. Here are some troubleshooting steps you can try:
Check the heating element: The heating element is responsible for heating the water during the wash cycle and drying the dishes at the end of the cycle. If the element is faulty, the dishwasher may stop mid-cycle and display the flashing lights you described. Use a multimeter to test the continuity of the heating element. If there is no continuity, the heating element needs to be replaced.
Check the thermostat: The thermostat is a safety device that prevents the dishwasher from overheating. If the thermostat is faulty, it may shut off the heating element prematurely, causing the dishwasher to stop mid-cycle. Test the thermostat using a multimeter. If it's not functioning properly, it needs to be replaced.
Check the control board: If the heating element and thermostat are functioning properly, there may be an issue with the dishwasher's control board. A faulty control board can cause various issues, including the flashing lights you described. If this is the case, you may need to replace the control board.
If you're not comfortable performing these troubleshooting steps yourself, it's best to contact a qualified technician to diagnose and repair the issue.
They should not wobble a lot. They have to be able to spin, but should not have a lot of lateral movement. See if you can remove the spray arm and clean out all the spray jets. If some are blocked at one side it causes the arm to not spin true and flat. It spin with one side high and one side low. The other problem may be incorrect loading of dishes.

Sounds just like my Whirlpool dishwasher. If you have the documentation that came with it look through it for a "reset" method to re-calibrate the dirt sensor in the unit. If you don't have the owners manual try to "Google" an owners manual or a "technicians" manual to find a reset or a re-calibrate procedure. Mine consisted of pressing certain control buttons at the same time, after which the unit ran through a calibration cycle that took about as long as a normal wash, and it has worked great ever since.
I called Frigidaire with these codes. They said it indicates a power failure happened (during a wash cycle, I suppose) and to do a hard reset. A hard reset is turning off the breaker for 30+ minutes and then flipping the breaker back on. This kind of worked, but simultaneous to the error codes, the push/pull latch on my dishwasher got set to the closed position while the door was open, so the door would not latch. I feel that this was the initial problem that caused these codes. So in my case, I had to manually rotate the latch open with bent piece of wire, to get it into the correct position first. Then the hard reset seemed fix the error codes. I was able to start a wash. It's running now.

It is very easy
Resetting the Dishwasher. Hold down the cancel button for at least 3 seconds. Find the cancel button on the far-right side of the control panel. To reset the dishwasher, hold this button down for 3 seconds or until the light display disappears or changes.
The Frigidaire Appliances company designed most of its dishwashers to visually alert and display to users that the door is ajar, via the "CL" code. The dishwasher won't start pumping in hot water or rotating the spray arms until the door is secure.
