Hello and welcome to just answer my name is ***** ***** I will be the one to assist you.
When the EF flashes with no beeping, it means there is too many suds, and you must use low suds washing powder with these machines,,,
When it flashes and beeps, it means there is a motor fault, the only thing you can do is set the machine to drain and spin, and run it to the end and start over. If the problem continues to be present, then this will be a motor problem with the machine.
Try unplugging the machine from the wall for one hour, then run a rinse cycle, followed by the drain and spin and see if it will clear, make sure you add no clothes or powder though, just flush it out after unplugging it from the power for 1 solid hour. Then try using it again and let me know what happens please.
