Beeps, then error blinking in display 'EFO'
The error codes are not shown in the owner's manual. They would be in the technical information for the washer. They are intended for service technicians. The chart of the error codes is shown below. The EF0 is a group code that indicates that one of the faults associated with error codes beginning with "EF" occurred. This group includes EF1, EF2 and EF5 as shown in the chart below. To determine the exact code of the failure, you can use the procedure in the second image to recall the specific code.
If the washer had excessive suds, you can likely drain it after the suds dissipate. Make sure that you are using HE (High Efficiency) detergent in appropriate quantities in the washer.
If the EF5 error occurred, you could have the hot and cold water lines switched on the back of the washer. You could also have a problem with the temperature sensor.
If the EF1 occurred, you likely have a drain problem. Check the drain line for kinks or clogs. To access the drain pump in the washer, you would need to unplug the washer and remove the bottom front service panel. If you access this area, you can check the pump. Be careful. If the washer tub is still full of water, it will drain out through the pump if your pull off any of the hoses to the pump. You can evacuate most of the water from the tub by using a wet/dry shop vacuum. A clog in the pump could be causing a drain problem.
