Frigidaire front-loading washing machines offer a control panel with keypads to set the desired wash cycle and any options, as well as monitor the progress of the wash cycle. Occasionally, if an error occurs with the washing machine, an error code will show up on the display instead of the standard cycle information. If this happens, such as the error code "E90," you can often fix the situation before having to call Frigidaire for help.
The E90 error code is not a common error but it may occur when the washing machine electronics get wet for some reason. This may happen if wet clothes are left in the washer for a prolonged period after the wash cycle ends or if the same load is washed repeatedly.
One of the first steps whenever an error code appears on a Frigidaire washer is to perform a simple reset to the machine. To reset the washer, press and hold the "Cancel" button for 15 seconds. Then try to set a new wash cycle and press "Start." Note that any clothes that have finished washing should always be removed promptly after the cycle is done.
If the cancel button reset does not remove the E90 error code from the display, try a full power reset. To accomplish this type of reset, unplug the washing machine and wait 15 minutes or more. Then plug the washing machine back in and make a new wash selection. If the error code does not return, normal function may resume.
Unfortunately, if the cancel button and/or full power reset attempts do not eliminate the E90 error code, it is very possible that the electronic control board will need to be replaced. If you have expertise with washing machines, you may be able to do this, but it is best to contact Frigidaire at 800-374-4432 for a service call.
