It says sud on the front wont start do i drain it manuelly?

you probably used too much detergent or the wrong type. These new front loaders take no-suds detergent, a shot glass half full worth. The suds get in the water level tube and the level sensor and everywhere else, and cause mayhem. Run some loads with no detergent at all to try to clean the suds out. If the thing works like it should sometimes, it's a cheap fix. The brain power to find a problem and fix it for good, not so cheap. Water Level Switch

Don't know if this is your problem but sometimes ours will appear to drain, but there is still a lot of suds that remains and trips the nd (no drain) indicator/lockout. We had to pour water in from a bucket to beat down the suds, then repeat several times to get all the suds out. First time I took off the back of the washer, disconnected the pump, then let the suds out. To much work.

I have the manual for this machine. Under "Code 21" it says the following:
"F21" (Drain Problem) Select STOP twice to cancel the cycle. Unplug washer or disconnect power. Check the following: Is the drain hose kinked? Is the drain hose frozen? Is the drain hose clogged? Is the drain hose more than 96" (2.4 m) above the floor? Plug in washer or reconnect power. Re-select cycle and press START. If the problem remains, call for service.
For "SUDS" code, the following:
"SUD" (Suds Routine) When excessive suds are detected, a suds routine automatically starts. This routine removes extra suds and assures proper rinsing of your garments. "SUD" is displayed during rinsing to inform you that Suds Routine was activated. Use only HE (High Efficiency) detergents.
Here is some more information that may help you as well:
"F" Codes other than F20, F21 and F22 Select STOP twice to cancel the cycle. Select DRAIN & SPIN if there is excessive water in the washer. Re-select cycle and press START. If the problem remains, call for service.
I hope this is of some help to you, Please rate and comment, Thank You

F21 indicates that the washer is having problems draining. Check the drain hose to see if it is kinked or if there is an obstruction in the hose.

SUD comes on every time excessive suds are detected. Not using the proper detergent will set this off faithfully. The machine will run a cycle to remove the excessive suds before completing the wash cycle.

You need to clean the drain filter by removing the 3 screws in the bottom of the front panel. Then you will see a white twist cap. Remove the filter and clean it out.

Sud

SUDS LOCK (Overdose of detergent detected during the wash cycle)

The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If “Sud” is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Potential Causes

A. If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
B. Check the drain hose and make sure it is not plugged or kinked
C. Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
D. Check / Clean Drain Pump Filter of foreign objects
E. Check Drain Pump
F. Check the Pressure Switch
G. Check CCU

Replace failed component.

sounds like you have a clogged/bead pump. removethe lower acess panel and from there youll see the pmp clean put remove thescrewout, and clearthe debris. BE WARNED THER WILL BE WATER BEHIND grab a towell or 2

Sud means you using to much soap and the f code means soap is locking the drain pump up and wont allow unit to drain and spin.

Try cycling the washer a few times without a very small load of clothes and no detergent. I assume that you are and have beenm using only HE type detergent and I suggest you try using about 1/2 to 1/3 the amount called for until your system is purged of any and all remaining detergent in the lines. Here are the manufacturers reccommendations to address your problem..

“SUD” (Suds Routine)
When excessive suds are detected, a suds routine
automatically starts. This routine removes extra suds and
assures proper rinsing of your garments. “SUD” is displayed
during rinsing and at the end of the cycle to inform you that
Suds Routine was activated. Use only HE (High Efficiency)
detergents.

Hope this helps you..

“F02” (Drain Problem)
Select PAUSE/CANCEL twice to cancel the cycle. Unplug
washer or disconnect power.
Check the following:
Is the drain hose kinked?
Is the drain hose frozen?
Is the drain hose clogged?
Is the drain hose more than 96" (2.4 m) above the floor?
