Essential Tips for Fixing LG Dishwasher Mid-Cycle Stops

  • Address Faulty Components: Check the lid latch, thermal fuse, electronic control board, motor assembly, fan, and chopper blade for defects.
  • Replace Thermostat or Lid Switch: If the dishwasher stops mid-cycle, it could be due to a faulty thermostat or lid switch malfunction. Replace them following safety guidelines.
  • Fix Electrical Issues: Repair or replace a melted wire harness and a defective control board.
  • Handle Water Issues: Check for a leaky water inlet valve or a clogged filter, and clean or replace as necessary.
  • Reset Your Dishwasher: Disconnect power for at least 10 seconds or up to 48 hours for a full reset.

Why does your LG dishwasher stop mid-cycle?

  • Faulty Lid Latch: Your dishwasher may halt if the lid latch is broken or loose.
  • Thermal Fuse Issues: A loose thermal fuse can cause mid-cycle stops.

Your LG dishwasher might experience a malfunction due to a damaged electronic control board. A leaky water inlet valve can also result in sudden stopping.

  • Motor Assembly Defects: A defective motor assembly might be the culprit.
  • Additional Causes:
    • Broken fan
    • Dirty chopper blade

Consult a technician if you encounter persistent faults or if the control panel displays an error code indicating a defect.

Regular troubleshooting can preempt overheating and further issues. Refer to the tech sheet for guidance on interpreting fault codes specific to your dishwasher model.

LG Dishwasher Stops Mid Cycle and Beeps?

#1. Thermostat

Your dishwasher relies on a thermostat to control the water temperature. If the thermostat is not working properly, it could shut off the heater too soon.

This leads to your dishes not drying as they should, and your dishwasher might stop in the middle of a cycle.

Signs of a faulty thermostat:

  • The dishwasher stops mid-cycle
  • The dishes remain damp, not drying completely

Steps to replace the thermostat:

  1. Turn off the dishwasher’s power.
  2. Open the panel and locate the thermostat.
  3. Remove it and test with a multimeter for continuity.
  4. If defective, replace it with a new thermostat.
  5. Reassemble the panel and restore power to test.

#2. Lid Switch

A less common but possible issue is the lid switch malfunctioning. If when you shut the dishwasher door and the switch doesn’t signal properly, your machine might stop running and begin flashing or beeping.

Identifying a lid switch problem:

  • Dishwasher stops unexpectedly
  • Flashing lights or beeping sounds occur after the door is closed

Procedure to change the lid switch:

  1. Disconnect the power and put on safety gloves.
  2. Remove the dishwasher door panels to access the latch.
  3. Unscrew the control panel and remove the old lid switch.
  4. Refer to a photo for wiring the new lid latch.
  5. Install the new switch, reassemble the door, and power up for a test run.

In both cases, if you’re unsure about performing these repairs, contact a professional for assistance.

LG Dishwasher Stopped Mid Cycle No Power?


#1. Melted Wire Harness

Your LG dishwasher needs electricity to run. A group of wires, called a wire harness, connects power to the parts inside. If this gets too hot, it can melt. When that happens, your dishwasher stops because it loses power.

Here’s how to fix it:

  • First, make sure your dishwasher is unplugged. This keeps you safe.
  • Next, take off the outside panels to see the wire harness.
  • Remember how the old wires are connected by taking a picture or writing it down.
  • Now, take out the old wires and carefully put in new ones in the same way.

#2. Defective Control Board

Think of the control board as the dishwasher’s brain. It tells your dishwasher what to do and when. If the control board breaks, it can’t send these commands, so your dishwasher might just shut off.

Steps to change the control board:

  • Begin by unplugging the dishwasher for safety.
  • Open the control panel area by removing the screws.
  • Use a tool, like a screwdriver, to take off the thermal fuse that’s stuck to the board.
  • Carefully disconnect the wires and push the tabs to free the old control board.
  • Replace it with the new board, reconnect everything, and put the fuse back.
  • Finally, put the panel back on and plug your dishwasher back in. Now it should work right!

LG Dishwasher Stopped Mid Cycle Water in Bottom?

#1. Leaky Water Inlet Valve

Your dishwasher needs a good water inlet valve to pump water efficiently. If this valve is leaky, water might end up where it shouldn’t be, like at the electric units.

This can cause short-circuiting and a pool of water at the bottom of your dishwasher. If you notice leaking, it’s best to have a technician check and replace the water inlet valve.

#2. Clogged Filter

A clogged filter might be the trouble behind your dishwasher stopping mid-cycle. Your filter traps food particles, but when it’s too full, it can block water flow and contribute to a short-circuited thermal fuse.

Here’s what to do:

  • Unplug your dishwasher from the power outlet.
  • Find and remove the filter near the bottom inside your dishwasher.
  • Clean the filter with hot water to wash away trapped debris.
  • Before running your dishwasher again, remove large food pieces from dishes to prevent future clogs.

Remember, regular maintenance of your filter can prevent unwanted leaks and keep your dishwasher running smoothly.

How Do I Reset My LG Dishwasher?

When errors show on your LG dishwasher, a reset might be needed. Here is how you can do it:

  • First, disconnect your dishwasher from the power source or switch off the circuit breaker. Wait for at least 10 seconds.
  • Next, press the power button to turn off your dishwasher.

This pause lets your machine clear out any saved settings or errors.

  • After waiting, reconnect your dishwasher to the power source or flip the circuit breaker back on.
  • Press the power button again to turn on your dishwasher, then start a new cycle.

Check if your dishwasher runs without issues now.

Alternatively, if the standard reset doesn’t work:

  • Unplug your dishwasher and leave it unplugged for about 48 hours, allowing it to fully dry out.
  • Then, plug the dishwasher back in and start a cycle to see if it operates correctly without interruptions.
