A UE error indicates an imbalance in the machine:
Ensure the machine is level and is on a solid floor (concrete or tiles, not wood or laminate) and ensure the feet are adjusted correctly as per the installation instruction supplied with your machine.
Best practice for loading is to ensure that you fully load the machine and leave only a 4 - 5 inch (10 - 12 cm) gap from the top of the metal drum.
Try not to mix heavy and light items in the same wash - To minmise imbalance errors wash heavy and light materials in two seperate washes.
If you find the machine sticking in a service wash, that is with nothing inside, then you may need an engineers visit.
