Your washer is designed to use a TINY amount of water. This conserves water and takes less energy to heat the water. Since it is so little water used any amount above a teaspoonful of detergent will reek havoc with the delicate controls on the machine.

Sud= Suds lock detergent overdose. Too much detergent, the wrong stuff, added to the wrong compartment, you gotta use HE soap and you gotta use the correct amount. You get that computer thinking suds is in there and the machine is gonna go into a tailspin. Because of the low amount of water
used in HE machines, it is important
to use an HE detergent (low sudsing)
which is specially formulated to work
best under these conditions. The two
most important considerations
of a front loading washer are suds
control and soil concentration.
First, the tumbling action in an
HE machine generates
more suds than a top loader.
Tumbling the clothes in and out of the
water breaks the water surface
causing air to be trapped in the solution,
creating suds or foam. Multiple problems
can occur from oversudsing, such as
flooding from suds overflowing out of
the machine, formation of a suds cushion
during the tumbling action which reduces
mechanical energy,and “suds lock” which prevents
the machine from effectively spinning out the
water. In the situation of suds lock, the
machine trys to FIX the foaming problema by
stopping the cycle momentarily to allow
the suds to dissipate and then adding cold
water. This routine the machine goes
through to correct for over-sudsing results
in loss of energy and water savings and
can significantly lengthen the cycle time
(sometimes by as much as 2x). HE detergents
prevent over-sudsing and allow for
better rinsing of suds. HE detergent matters in
soil management also. Though HE washers
use about 1/3 of the water of a
top loader, the concentration of soil in the
load is much higher due to the larger
loads. To handle the higher amount of
soil, many HE detergents are specially
formulated with soil suspending ingredients
to prevent soil from re-depositing
onto clothes. Only use detergent with HE marked on it.
Use the correct amount.
The technical data sheet along with that
pesky clogged pump is located behind the
toe kick panel; remove the screws under the
bottom front edge of the washer. Tip the appliance
back to get to them screws. With the screws
removed, the panel will comes down and off.
