While I was out of town on business, my wife reported to me our nearly 7-yr old Frigidaire (Electrolux) GLTF2940FS2 Front Loading Clothes Washer started display & reporting the E90 error & beep code. Looks like she figured out unplugging it for a bit and plugging it back in at least temporarily cleared the error.

When I returned from training, it happened to me and I was able to clear the code twice by unplugging then plugging it back in. The third load I tried it on, unplugging then plugging it back in didn't do the trick. So I removed the top panel and unplugged then replugged the main control board connector. This cleared the code and allowed the wash cycle to complete. Now none of the previous techniques will clear the problem. I can't seem to find out what the E90 code is actually reporting. The manual under the top cover does not list this code.

There are two control boards on this machine. The main control board and the motor control board. I would like to be able to go into diagnostic mode to rule out one of them. Unfortunately, unless I can clear the error E90 code first, I will be unable to enter diagnostic mode.

What could be the problem? Better yet, what could be the fix? I posted this on another forum but have not received a response. Thanks for looking guys and gals. :)

A communication error is typically E90. Try to unplug and re-plug in all of the connectors to and from each of the control modules. Sometimes there is a build up of corrosion on the connections. You could also try using a connector cleaner, it comes in a spray can (I think its mostly alcohol). Spray the connections and the terminal ends. Here is a picture of an example although I'm not promoting one brand over another. I've checked and we don't carry it here at APP.

Thanks for the tip. I did try to reseat the connectors but I didn't try the electronic cleaner. I decided to go ahead and order the main control board. It arrived yesterday and I installed it. Although I couldn't get into diagnostics mode, the new control board got our washer up & running. If it happens again, I will try the electrical contact cleaner first. ;)
