receiving error codes 35 and 27

David error F27 is a water level error and F35 indicates a water level pressure sensor failure. Since you already replaced the switch you do want to make sure that the air tube is not kinked, obstructed or has a leak. Try this since both codes you mentioned are indicators of a water level problem. Remove the supply hoses from the faucet and the fill valve. There should be small filter screens that you can remove and clean/replace. Run the water from the faucets for a few minutes. Remember to put some sort of bucket under the faucet. This might clear any debris. After that remove the lower panel, and remove the filter from the drain pump and check and clear any debris from the filter and the pump. 1. Take off the lower front panel.Remove the bottom front access panel just remove the 3 Torx screws on front bottom of machine. Slightly lift the panel and pull the bottom towards you

2. Turn the pump filter cover counter-clockwise by hand and remove. Place a bucket or pan underneath it since you will get the water spilling out of there. Removing the filter should remove all water from your washer. You also want to remove the air hose from the water level switch, and blow into the hose,as hard as possible, to clear any debris. Also, do not forget to check all wires and connectors to make sure they are all still properly seated. Remember that water and electricity do not mix well. Unplug your machine anytime you work on it. Hope this helps, good luck.
