Sarah Mitchell Key Takeaways
- LG dishwashers include leak detection systems — error code LE indicates detected water in the base pan
- Check the door gasket monthly for cracks that could lead to water damage on your kitchen floor
- Never use regular dish soap in a dishwasher — it creates excessive suds that can cause flooding
- Ensure the dishwasher is connected to a GFCI-protected circuit for electrical safety
The Bottom Line
Dishwashers present primarily water-related safety risks. Regular gasket inspection, using only dishwasher-specific detergent, and maintaining the leak detection system keep these risks minimal.
LG dishwasher safety — here is what every homeowner should know.
LG washer safety — here's what you need to know.
LG dishwashers are generally safe appliances with multiple built-in safety features. Understanding the potential hazards and maintaining the safety systems keeps your kitchen protected from water damage and electrical issues.
Water Leak Prevention
Water damage from dishwasher leaks can be extensive, especially in kitchens with hardwood floors or when the dishwasher is on an upper floor. LG dishwashers include a leak sensor in the base pan that triggers error code LE and stops operation if water is detected outside the tub. To support this system, inspect the door gasket monthly for cracks, hardening, or debris that prevents a proper seal. Check water supply line connections quarterly for drips. If you notice water on the floor after a cycle, address it immediately — even small leaks can cause mold growth and subfloor damage over time.
Detergent Safety
Never use regular liquid dish soap in your LG dishwasher. Regular dish soap creates massive suds that overflow through the door seal, flooding your kitchen floor. Use only detergent specifically formulated for dishwashers — pods, tablets, or liquid/powder dishwasher detergent. Store dishwasher detergent pods away from children — they are a serious poisoning hazard and can be mistaken for candy. LG recommends placing detergent in the dispenser, not loose in the tub, for proper release timing.
Electrical Safety
LG dishwashers should be connected to a dedicated, GFCI-protected circuit. The National Electrical Code requires GFCI protection for dishwasher circuits in new installations. If your home was built before this requirement, consider having an electrician upgrade the circuit. The combination of water and electricity in a dishwasher makes proper grounding and GFCI protection essential. Never attempt to repair electrical components yourself — always use a qualified appliance technician.
Loading Safety
Load sharp knives with blades pointing down to prevent cuts when unloading. Secure lightweight plastic items so they don't flip over and fill with wash water, or worse, fall onto the heating element and melt. Don't wash items that aren't dishwasher-safe — certain plastics can melt or deform, and some metallic items can create sparks. Keep small items in the silverware basket rather than loose on racks where they can fall through and block the spray arms or drain.
Installation and Maintenance Safety
Proper installation is critical for dishwasher safety. The drain hose must include a high loop or air gap to prevent wastewater backflow. The dishwasher must be level to prevent door seal failures and leaks. The supply line needs a accessible shutoff valve that you can reach quickly in an emergency. Know where both the water shutoff and the electrical breaker for your dishwasher are located — in a leak emergency, you need to cut both water and power quickly.
