I keep getting a SUD error, I have stopped the cycle and reset by unpluging the washer, it keeps showing the SUD error. What should I do?

This code indicates that an apparent sudsing condition is detected. It happens when a non-HE detergent is used. Run a cycle without detergent or allow the machine to fill then drain it to make sure suds are removed. The problem is in draining if the code still flashes even no detergent is used.

Unplug the machine or disconnect power then remove the three screws attaching the bottom of the lower front access panel and pull the panel down and off. Once the panel is off, you'll find the drain filter attached to the drain pump.

Place a container or a piece of towel underneath the filter to catch spillage. You may need to drain the water from the machine by putting the end of the drain hose over a container on the floor. Position the container as low as possible to extract as much water.

Remove the filter by turning the knob counterclockwise and clean it. Also take a moment to inspect the drain pump impeller by reaching it in with your finger and turning it. The impeller should turn freely. Otherwise, replace the drain pump.
