So, why does your LG dishwasher stop mid-cycle?
If your LG dishwasher stops midway during the wash cycle, it’s often because of a faulty lid latch assembly or a loose lid latch. Other faults cause your LG dishwasher to stop mid-cycle.

LG Dishwasher Stops Mid Cycle and Beeps?
When your LG dishwasher stops and also beeps during the wash cycle, your dishwasher might not be sensing water temperature.
This will cause it to stop and shut the functions down.
Your function buttons will become unresponsive, and the machine will start beeping. This is a safety measure your appliance uses to prevent accidents like electrocution.
To reset the dishwasher:

- Sequentially press the buttons, high-temperature wash, and heat dry, twice.
- The diagnostic cycle of the machine will start.
- Your machine should run as usual now.
- If this problem persists, some of your components might be faulty.
These faulty components are:
If the water in the dishwasher gets to a particular temperature, the thermostat shuts the heating unit to prevent the component from overheating.
When the thermostat malfunctions, the heating unit will go off too early, which would make the dishwasher run at a low temperature.
The high temperature dries your dishes faster during the wash cycle. But the cool temperature might stop your cycle midway and keep it from completing.
To check your thermostat efficiency, test its electric continuity with a multimeter. If there is no electricity, your thermostat needs replacement.

LG Dishwasher Stopped Mid Cycle No Power?
If your LG dishwasher stops mid-cycle and the power goes out in your dishwasher, it is usually because of a melted wire harness and a damaged control board.
#1. Melted Wire Harness
It is a group of wires inside the dishwasher that connects the power to components of the dishwasher. It is advisable to change the wire harness anytime you change the thermal fuse.
To replace the wire harness:
- For safety reasons, disconnect the dishwasher from the power outlet.
- Detach the panels to access the wire harness.
- Capture the positions of the old wire harness before taking it out.

#2. Defective Control Board
The electronic control board regulates the functions of the dishwasher. If your wire harness is still in good condition, your control board is faulty.
If your control board is defective, it might turn off the power of your dishwasher during a wash cycle.
To replace your control board:
- Disconnect the power source from the dishwasher.
- Unscrew the control panel to detach it.
- Pry the thermal fuse attached to the control board with a screwdriver.

LG Dishwasher Stopped Mid Cycle Water in Bottom?
If your dishwasher stops mid-cycle and leaves the water at the bottom, it is usually because of a short-circuited thermal fuse.
The thermal fuse detects overheating in the appliance and trips off to protect the dishwasher motor.
If the thermal fuse blows, it would need replacement.
A faulty thermal fuse can also be due to:
#1. Leaky Water Inlet Valve
The water inlet valve pumps water into the dishwasher chamber. If the valve is faulty, water will leak on the electric units and to the bottom of the dishwasher.
In addition, it will cause the fuse to short-circuit. You should call a technician to check the water inlet valve and replace it.
#2. Clogged Filter
A clogged filter could have short-circuited your thermal fuse if your washer stops mid-cycle.
This is because the filter catches all the food particles, and, over time, the filter can get blocked.
This causes the water to flow towards the bottom of the dishwasher. To clean a clogged filter:
- Unplug your machine from the power source.
- Locate your filter. It is usually close to the bottom of the dishwasher.
- Wash the solid dirt away with hot water and replace it.
- Always clean large solid pieces of food from the dishes before putting them in the dishwasher for washing.
