LG Washer Error Code E7 — SideKick Installation/Stacking Error
What this means
The E7 error code indicates a problem with the stacking switch on the LG SideKick pedestal washer or that the SideKick is not properly installed under a front-load washer or dryer. The stacking switch confirms that the units are properly aligned and secured together.
Step-by-step fix
3 stepsVerify proper installation
Ensure the SideKick is correctly positioned directly under a compatible LG front-load washer or dryer. The unit must be level and the mounting hardware must be properly secured.
Check the stacking switch
Locate the stacking switch (a magnetic or mechanical switch that detects the upper unit). Make sure it is not blocked or damaged.
Power-cycle the unit
Unplug both the SideKick and the upper unit for 60 seconds, then plug them back in.
When to call a professional
If the installation is correct and the stacking switch has failed, a technician can replace the switch.
