If you’re facing the same issue or want to be prepared, here’s my comprehensive guide to help you navigate this error and make informed decisions about buying or maintaining a Honeywell dehumidifier.
What Does Error Code E3 Mean?
From my experience, the E3 error code on a Honeywell dehumidifier usually indicates a problem with the humidity sensor or a related malfunction in the unit’s electronic controls. This means the dehumidifier is having trouble detecting or regulating humidity levels correctly.

Here’s what I did to fix the E3 error before considering a replacement:
- Unplug and Reset: I unplugged the unit for a few minutes and then restarted it to see if the error cleared. Sometimes, a simple reset helps.

- Check Connections: I inspected the wiring and connectors inside the unit for any loose or damaged parts.
- Review Placement: I made sure the dehumidifier was operating within the recommended temperature range and not near sources of extreme heat or cold.
If these steps didn’t resolve the issue, I knew it might be time to contact Honeywell support or consider repair options.
When to Consider Buying a New Honeywell Dehumidifier
After troubleshooting, if the E3 error persisted, I weighed the cost of repair against buying a new unit. Here are some situations when I decided buying new was better:
