Little pro tip:
Samsung Washer Error 4E means the washer isn't getting enough water. Likely means the filters need to be removed and rinsed.
When we redid our laundry area I put slider pads under the washer dryer which made movin the washer very simple. +1 for me.
Then, and this is an important part that I forgot...
Turn the water off before removing the hoses from the washer.
You do that the rest is fairly straight forward. However... one other little thing.
Once you clean the filters and reattach the hoses
Before you push the washer back and use it, turn the water back on.
So for those keeping score it's MQS 1, idiocity 2.
