What E21 means on your Kenmore dryer (kenmore e21 error)
A kenmore e21 error is a verified LG code, confirmed on LG’s own USA support pages, meaning a drain pump error on your LG-built Kenmore condensing/ventless dryer (795/796-prefix). This applies to condensing dryer models that pump condensate out rather than venting to the outside.

Symptoms
The signs below help confirm you are dealing with this condition rather than a different problem on your Kenmore dryer. 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 E21
- Condensate is not being pumped out, and the reservoir fills or overflows
- No pump sound is heard during the cycle
- The cycle stops partway through
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.
- Failed condensate drain pump — the pump is not running or not moving water
- Pump wiring failure — the pump is not receiving power correctly
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.
- Power-cycle the dryer at the breaker and attempt a restart.
- Confirm the condensate drain hose (see E13) is not the underlying blockage.
- Avoid repeated resets if E21 returns immediately.
- Book service for the condensate drain pump.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the condensate drain pump and pump wiring. The correct part for your Kenmore dryer 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.
