What Ed4 Means
Ed4 means the liquid softener level in the ezDispense reservoir didn't decrease as expected, and LG's control board specifically reads this as an open circuit in the softener pump, per LG's front-load washer Help Library article.
Common Causes of Ed4
- Dried softener residue blocking flow, mimicking a pump fault
- Open circuit (broken electrical connection) in the softener pump wiring
- Softener pump itself has failed
🔧 One Safe Check You Can Try
Confirm liquid-only softener is being used and clear any residue from the tray; an open-circuit reading suggests a wiring or pump fault that cleaning alone won't fix.
⚠ Why You Shouldn't Go Further Than That
- Like Ed2, an open-circuit code points toward an electrical fault in the pump rather than a simple clog - if the basic cleaning step doesn't clear it, it needs a technician.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
