Doet front loader. First the

you should have gotten an error code if a cycle does not complete.

one of the issues that can be checked for is blockage of the filter in the bottom access panel.
remove the 3 screws on front bottom of access panel ,
then remove/unscrew the large filter access port and check for debris.
some water will be maintained there so have some rags or towels ready.
if you still have any issues get the readout code on the front of unit and any other symptoms, issues ,sounds it makes.
