How to fix EdgeStar laundry center error code E21 (safe owner checks)
- Write down the code and model number. Note exactly what the display shows (E21) and copy the full model number from the rating label, so you can confirm this chart applies to your laundry center and order the right parts.
- Check the drain hose. Check the drain hose for kinks and clogs.
- Clean the drain filter. Clean debris from the coin trap.
- Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
- Test and decide. Run a short cycle or restart and watch the display. If E21 comes back after these checks, stop using the washer for this function and call a technician, because the remaining causes need meters or part replacement.
The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the EdgeStar laundry center error-code chart published by Sears PartsDirect, rewritten for safe owner use.
