samsung dishwasher stops mid cycle

Are you worried that your Samsung dishwasher stops mid-cycle? It is possible to fix it if you have the patience to investigate your dishwasher thoroughly until you find the culprit.

A Samsung dishwasher that stops mid-cycle might have a broken or loose door latch or a clogged filter. If those are fine, it is also possible that some more vital component, such as the thermal fuse or control board, is at fault.

Below we will tell you everything about the issue you are facing so you understand the causes and how you can fix it.

Remember that you should not try to fix it yourself when the dishwasher is still under warranty.

If its warranty has expired, fixing it yourself is the cheapest option.

Samsung Dishwasher Stops Mid Cycle – Reasons

reason why dishwasher stops mid cycle

Has your Samsung dishwasher stopped working mid-cycle? That issue will happen when some internal component is not working as it should.

There is a lot of room for investigation, but the most common causes are these:

Loose Door Latch

It is possible that the door latch of your dishwasher is loose and starts opening when there is movement inside. Then the cycle stops.

Thermal Fuse

The thermal fuse is responsible for all sorts of things inside the dishwasher. When it is shorting out, cycles will not go through.

Control Board

A glitching control board will transmit a lot of errors through the system, and it can be at fault when cycles stop midterm.

Clogged Filter

Water can’t get out properly when the dishwasher’s filter is clogged. The dishwasher will detect it, stopping the cycle.

Drain Pump

Some cycles will drain mid-cycle, so if the drain pump is damaged, the cycle will stop completely.

With enough information about the causes, it is perfectly possible to fix your Samsung dishwasher stopping mid-cycle.

However, be aware that fixing it will require some tools and following practical steps. Also, you might have to buy replacement parts.

1. Investigate The Door Latch

The door on your dishwasher may have a somewhat loose latch. As a result, it closes completely but not firmly, and it starts opening so that the dishwasher detects it mid-cycle.

You can discover such a malfunction by simply observing. Here is how to fix it:

  1. Open the dishwasher door; 
  2. Locate the door latch assembly (top of the dishwasher door);
  3. Remove the screws securing the door latch assembly;
  4. Pull the door latch assembly out;
  5. Disconnect the wires from the old latch;

Install The Replacement

Once you have removed the defective part, you must search for a replacement. First, ensure you buy a compatible one.

Once you have it:

  1. Connect the wires to the replacement latch; 
  2. Insert the new door latch assembly into the door;
  3. Secure it with the screws you removed;
  4. Test the new door latch to ensure that the door closes all the way.

Once you have installed the new door latch, you can run a test cycle on the dishwasher.

2. Clean The Filter

If the door is not the culprit behind the mid-cycle stop, then you must proceed to investigate the filter.

Dishwasher filters accumulate a lot of dirt, and when you forget to clean them, they interrupt the appliance’s regular functions.

Here is how to ensure the filter gets spotless:

clean dishwasher filter
  1. Locate the filter on the bottom of the dishwasher;
  2. Turn it until it becomes loose;
  3. Remove it;

Some filters have a cover, so you have to take the cover before removing them.

After that, you can clean by following these steps:

  1. Fill a basin with water, vinegar, and bicarbonate;
  2. Let the filter on the basin for some minutes;
  3. Take the filter and put it under a tap;
  4. Scrub all the remaining dirt;

Once the filter is dry, you must reattach it to the dishwasher and test if the next cycle goes through.

3. Find The Thermal Fuse

The next culprit on our list is the thermal fuse. Usually, a blown thermal fuse will prevent the dishwasher from even starting a cycle.

If the dishwasher stops mid-cycle, the thermal fuse may be shorting out.

You will have to investigate the following:

  1. Turn the appliance off and unplug it;
  2. Unscrew the control board;
  3. Remove the control board;
  4. The thermal fuse is a little cylindrical part with two cables;
  5. Detach the cables and take the fuse to examine.

Test The Fuse

You will have to test the thermal fuse with a multimeter:

  1. Touch the probes to the fuse’s wires;
  2. Set to continuity.

The reading on the multimeter will probably float if the thermal fuse is damaged. It can also show no reading at all. 

Replace The Thermal Fuse

The hardest part about installing a new thermal fuse can be finding the replacement.

You must get a thermal fuse with the same electrical rating that fits your Samsung dishwasher. Then:

  1. Connect the fuse’s wires to the control board;
  2. Reattach the control board;
  3. Test a cycle to see if it goes through.

4. Check The Drain Pump

As the name implies, the drain pump is responsible for getting water from the dishwasher.

Once it gets defective, it won’t be able to drain all the water, which will halt the cycle. Investigating the issue and replacing the pump is not a hard task.

  1. Position the dishwasher so you can see its bottom;
  2. The drain pump is near the motor;
  3. Detach the screw/clip that secures the pump;
  4. Take the pump so you can check it.

Test The Drain Pump

You need to test the drain pump before assuming it is truly defective:

  1. Touch a multimeter to the pump;
  2. Adjust for continuity;
  3. Wait for the results

The correct reading for a drain pump is between 160 and 200 ohms.

Install A New Drain Pump

The next step is buying a replacement drain pump. You can find it at online retailers or a local spares shop. 

  1. Check that the new part fits in;
  2. Secure it with the clip or screw;
  3. Reposition the dishwasher correctly;

If the drain pump was at fault, the dishwasher should work as new.

5. Replace The Control Board

A mid-cycle stop on your Samsung dishwasher can also be traced back to the control board.

It might be faulty and deliver wrong commands when the appliance is washing the dishes.

You need to check if some commands are defective and if the appliance shows other odd behaviors.

If that is the case, start by uninstalling the damaged board:

  1. Open the dishwasher’s door;
  2. Unscrew the internal door’s screws;
  3. Detach the outer door panel out of the inner panel;
  4. Unplug the wire harness of the user interface control;
  5. Take the control panel away;
  6. Level up the locking tab;
  7. Push the control board left;
  8. Unleash it from the inner door panel;
  9. Let go of the cover locking tabs;
  10. Detach any parts still attached.

Install The New Control Board

A replacement for the Samsung dishwasher control board is easily available on the internet, depending on the model of your appliance.

Once you have the new component in your hands, you have to do this:

  1. Remove the new control board’s cover;
  2. Connect the board’s wires to the appliance ones;
  3. Attach the wire harness connector brace;
  4. Snap the connector box cover;
  5. Place the electronic control board cover;
  6. Push the new component until it locks;

Don’t forget to reattach the door and install all the screws you have removed.

After that, you must test a washing cycle. After that, you should no longer have trouble getting the dishes clean.

What We Learned

When the Samsung dishwasher stops mid-cycle, you must first check if you are placing the dishes correctly and keeping the dishwasher clean.

If those are not the causes, it is necessary to investigate some inner components. Only do that if you feel comfortable disassembling your appliance.
