The washing machine keeps blinking sud what does this mean? It won't finish the cycle.. it is a kenmore front loader HE 5t

Either you have too much of the correct detergent in there or the wrong detergent in there. Here are a few of the errors:
1)Water fill problem: water took more than 10 minutes to fill to desired level sometimes indicated as a LF/IE or long fill/inlet error. Water valve screens clogged, hoses kinked, low water pressure, unpaid water bill. Check hose, clean screens.
2)Excessive vibration: noisey,roar, knocking noises. Bad damper,bearing or broken trunion. no error code
3)Dispenser drawer open/detergent in wrong compartment: washer will not operate with drawer open or cleaning products in wrong compartment.
4)Washer won't drain: clogged pump/filter, slow or clogged drain usually indicated as a LD/DE, if a code is given (long drain/drain error) Clear pump of objects
5)Drum overfilled: usually caused by sediment in the water level pressure sensing tube going up to the main control.Find it and blow out the sediment, re-secure pump out water and retry.
6)Door open, Door not latched, clothes/objects keeping door from completly closing. Tighten door latch, add washers if nessesary to make good contact and close door tighter in case of leaks.
7)Cold water does not enter washer: hoses connected backwards. Oops.
8)Oversudsing: Wrong Detergent, turbidity monitors pick up particles in the water and judge soil content then the washer allows for extra time to wash the clothes, if the wrong detergent is in there the machine thinks that is too much and declares a suds error. Remove detergent, retry
9)Locked motor: error LE,loose connection,broken wire/hallsensor, motor overheated/failed.
10)Water heating error, hE, the thermister/heater is out.

It will post a sud error if it cant drain properly. Either the wrong detergent!, or the pump is clogged. Both will cause this. Drain as much water from the machine as possible. Sometimes I use a towel draped over the machine to a bucket on the floor, after you got as much water out by hand. The towel creates a wicking/siphon action. More than likely though you have to remove the bottom panel and clean the filter or the pump.
