Why does my lg dishwasher run for 3 hours? (solved!)

If you’re wondering “why does my LG dishwasher run for 3 hours,” you’re not alone. Many LG dishwasher owners have experienced this issue, and it can be frustrating to deal with. In this blog post, we will explore the potential causes of this problem and provide step-by-step solutions to help you resolve it.

Causes of a 3-Hour Dishwasher Cycle

There are several factors that can contribute to a dishwasher cycle that runs for an excessively long time, including:

• Incorrect Water Supply: If the water supply to your dishwasher is too low, it will not be able to fill properly and the cycle will be extended.
• Clogged Drain: A clogged drain can prevent water from draining properly, leading to a longer cycle time.
• Faulty Water Inlet Valve: A malfunctioning water inlet valve can restrict water flow, causing the dishwasher to run for longer.
• Overloaded Dishwasher: Overloading the dishwasher can prevent dishes from getting clean and extend the cycle time.
• Dirty Filter: A dirty filter can block water flow and slow down the cycle.
• Faulty Heating Element: A faulty heating element can prevent the water from heating properly, leading to a longer cycle.
• Sensor Issues: Malfunctioning sensors can provide incorrect information to the dishwasher, causing it to run for longer than necessary.

Troubleshooting Steps

To resolve the issue of a 3-hour dishwasher cycle, follow these troubleshooting steps:

1. Check the Water Supply: Ensure that the water supply to your dishwasher is turned on and that the pressure is adequate.
2. Clean the Drain: Remove any food debris or other obstructions from the drain hose and filter.
3. Test the Water Inlet Valve: Disconnect the water inlet hose and check for water flow. If there is no water flow, the valve may be faulty.
4. Unload the Dishwasher: Remove any excess dishes from the dishwasher to avoid overloading.
5. Clean the Filter: Remove and clean the dishwasher filter regularly to prevent clogs.
6. Inspect the Heating Element: Check the heating element for any damage or corrosion. If it is faulty, it will need to be replaced.
7. Reset the Dishwasher: Unplug the dishwasher for 30 seconds and then plug it back in. This may reset any malfunctioning sensors.

• Use the Right Detergent: Use a detergent specifically designed for dishwashers.
• Load the Dishwasher Properly: Avoid overloading the dishwasher and ensure that dishes are placed correctly.

• Check for Leaks: Regularly inspect your dishwasher for any leaks, which can waste water and extend the cycle time.
• Calibrate the Dishwasher: Some LG dishwashers have a calibration feature that can optimize the cycle time. Refer to your user manual for instructions.
