What Does an ER10 Error Code Mean on Your Dri-Eaz Dehumidifier?
If your Dri-Eaz  Series 1 or Series 2 Compact dehumidifier is displaying an ER10 error code, here's what you need to know.

Which units this affects: 
ER10 codes appear on units equipped with the Command Hub touchscreen control, including:

  • Revolution LGR, PHD 200, LGR 3500i, LGR 6000Li, LGR 6500XLi, LGR 7000XLi, Syclone 145, and Syclone XL

  • DrizAir 1400 and LGR 5000Li (Series 2 Compact)

Common causes

Two operating conditions are the most frequent triggers for an ER10 code:

  • Using an extension cord. Extension cords can cause voltage drop, which the unit reads as a fault.

  • Operating above 100°F. Running the dehumidifier in ambient temperatures above the rated 100-degree threshold can also trigger the code.

Do not use extension cords, and do not operate the unit above 100°F. Avoiding these two conditions is the easiest way to prevent the code from appearing in the first place.

It's also worth confirming the unit is running the most current firmware. Outdated firmware can contribute to error codes and other performance issues. The new Dri-Eaz SYNC App makes it easy to check for and install updates.

How to clear it

The reset runs through a hidden service menu on the Command Hub display. In short: open the menu, tap into the second screen, tap the bottom-right corner five times to reveal the service icon, and enter a password to access the reset function. The exact steps and password differ slightly between the Series 1 Command Hub and the Series 2 Compact models, so confirm which unit you have before starting. Full step-by-step instructions, including the passwords for each model line, are available here:

Only attempt this reset if you've been instructed to do so — this menu isn't meant for routine use.

If the error comes back:

Don't keep resetting an ER10 code that keeps returning. A recurring error, especially without a cord or heat cause present, usually points to something that needs a closer look.
