What SUD means on your Kenmore washer (kenmore lg sud error)
A kenmore lg sud error is a verified LG code, confirmed on LG’s own USA support pages, meaning your LG-built Kenmore washer (795/796-prefix) has detected too many suds and is automatically running an extended suds-reducing cycle. This is LG’s own version of an oversudsing condition — a separate, distinct code from the similarly named “Sud/Sd” problem already documented on the Whirlpool-built Kenmore washer platform. Always confirm your washer’s model prefix (795/796 vs. 106/110/198/664/665/850) before assuming which platform’s guidance applies.
Symptoms
The signs below help confirm you are dealing with this condition rather than a different problem on your Kenmore washer. You may notice one of them or several together, and they can appear gradually or suddenly after a power event, a wash or cook cycle, a spill, or recent installation or service.
- The display shows SUD
- The cycle runs noticeably longer than normal with extra rinses
- Visible excess foam in the drum during wash
- The washer eventually finishes the cycle on its own
Common causes
Several different problems can produce these symptoms. Working through the most likely causes in order separates a quick owner-level check from a problem that needs trained service and the correct Kenmore parts.
- Too much detergent — using more than the recommended amount produces excess suds
- Non-HE detergent in an HE washer — regular detergent foams far more than high-efficiency formulas
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where mains voltage, gas, a hot oven cavity, water, or a sealed component is involved, and hand the rest to a qualified technician.
- Reduce the amount of detergent used on future loads and confirm it is an HE detergent.
- Allow the automatic extra rinse cycles to finish without interrupting them.
- Run the Tub Clean cycle periodically to help clear residual detergent buildup.
- If SUD recurs with correct detergent and amount, further diagnosis is needed.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the detergent dosing and drain pump filter. The correct part for your Kenmore washer is matched from the model and serial number, and genuine OEM components are fitted through trusted parts suppliers rather than generic substitutes so performance, safety, and the appliance long working life are all protected. Confirming the failed part before ordering avoids replacing more than the problem actually requires.
When to call a technician
SUD is a normal automatic response to oversudsing on this LG-built Kenmore washer; a technician is only needed if it keeps recurring after detergent type and amount are corrected. This condition is rated Low severity, so there is no emergency — but if the same SUD keeps returning after the checks above, a technician should confirm the cause before any part is replaced. As an independent repair service we are not affiliated with the manufacturer, and we work only with experienced, skilled technicians and genuine OEM parts from trusted parts suppliers, with our workmanship backed by a 30-day labor warranty. When you book, have your Kenmore washer model and serial number ready so the right part for your exact build can be matched before the visit and the SUD condition resolved in as few trips as possible.
