There are some error codes on the Frigidaire devices, that is pretty difficult to decipher, and the I50 combination is one of them. On the older models or the ones without any display, the same error is reflected by the 5 times blinking of the “End” light bulb. It can be whether the problem of the drain system or the washing motor.
The control module malfunction and the failure of the pump can also cause the indication of the I50 code, so as you can see, all the possible options are different and not easy to fix, this is why it is highly recommended to call to the service center in case you see this alphanumeric combination on the display of your Frigidaire appliance.
Of course, you can always try to reboot your machine by switching it off and unplugging from the main power for 15 minutes. If the code is still there after you switch the machine back on, try to press “Cancel” and then turn the power off for five more minutes. If it didn’t help, ask an experienced specialist for professional diagnostic.
