Model compatibility: KitchenAid reuses codes across series and model years, so Sud may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Per KitchenAid's washer documentation, "Sud" means the control detected a possible suds lock and automatically starts a suds-removal routine — it is a protective response, not always a hard failure. If the problem persists after a reset, book Artisan Repair for independent KitchenAid diagnosis with your model and serial numbers. Not an official KitchenAid service center.
Signs
Symptoms you may notice
The washer may extend the cycle while trying to remove excess foam.
Spinning or draining can be delayed.
The message can clear after suds are reduced even if no part has failed.
Why it happens
Possible causes
Too much detergent.
High-sudsing detergent or detergent not intended for the washer.
A drain/recirculation condition that prevents foam from clearing normally.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Use only HE detergent in the amount recommended for your load size
If "Sud" appears, let the automatic routine finish rather than adding more cycles
Run a Rinse/Spin, then a Normal cycle with no detergent to clear built-up suds
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Please avoid
What not to attempt
Do not open internal panels or access high-voltage components
Do not bypass door locks, safety switches or interlocks

When to call a technician
If the safe checks do not resolve the condition, schedule an independent KitchenAid appliance diagnosis. Provide the full model number and a photo of the Sud display so the technician can start with the correct model-specific code map.

For the record covered by this page, Sud relates to possible suds lock; the washer starts a suds-removal routine. Confirm the exact definition against the full model number before ordering parts or authorizing an internal repair.
You can correct an obvious external condition and use the normal owner-approved restart or acknowledgement procedure. If the same code returns, clearing the display again does not repair the cause.
Only if the condition is clearly a normal status/maintenance indication and the appliance is operating normally. Stop using it for smoke, burning odor, arcing, repeated breaker trips, uncontrolled heating, gas odor, active leakage near electrical parts, or a significant loss of refrigeration.
No. The code identifies a condition or diagnostic path. Model-specific testing should confirm the failed component before parts are ordered.
