Samsung WW80J555FX/EU Washing Machine PCB & Intermittent Problem Solved

Repairing a Samsung WW80J555FX/EU Washing Machine Printed Circuit Board (PCB)

Are you dealing with a frustrating intermittent fault on your Samsung washing machine, where it gets stuck on a program with just minutes left, refusing to complete the cycle? If so, you're not alone.

In this comprehensive guide, we will show you how to change the printed circuit board of a Samsung WW80J555FX/EU washing machine.

This particular model, an 8-kilo eco bubble, is known for having an intermittent fault where it gets stuck at one minute, four minutes, eight minutes, etc., during a wash or spin cycle. The machine fails to complete the cycle and you need to manually stop it to regain access, which can be quite depressing.

Please remember that, when working with washing machines or any electrical appliances, safety should always be your top priority, and we also suggest you watch our video.

Identifying the Problem

The first step in repairing your Samsung WW80J555FX/EU washing machine is identifying the problem. In this case, when you set a quick daily wash, the machine starts as normal. It fills with water, empties it, and the cycle begins. However, as the cycle advances, it often gets stuck around two to three minutes before completion. This issue can even occur during the last 10 or 14 minutes of the cycle.

The most common occurrence is during a spin cycle, where it freezes at one minute and remains so for an extended period, often up to 20 or 30 minutes. This requires a manual shut off to regain access to the machine. This kind of intermittent fault can prove highly frustrating and challenging to diagnose.

That's why diagnosing this intermittent fault can be a bit tricky, but the best way to figure out what's wrong is by observing the machine's behavior during a cycle. If it stops repeatedly and fails to advance, especially during the spin cycle, the issue might lie with the main motherboard. Briefly:

1. Program the Machine: Turn on the machine, select a quick daily wash, and press start. The machine will go through its normal process which is filling with water, emptying, and running the cycle.
2. Observe the Fault: The machine typically jams when it reaches the last few minutes. If this happens, press pause and start again to see if it progresses.
3. Test the Spin Cycle: Turn the machine on, select the spin cycle, and see if it jams.

If the machine stops with one minute left, this indicates an intermittent fault likely caused by the main motherboard or another component.

Checking Other Components of Samsung WW80J555FX/EU Washing Machine

Before replacing the motherboard, test all other components:

1. Heating Element: Perform a continuity check to ensure it has the correct values using an Ohm's law calculator.
2. NTC Sensor: Ensure it's functioning correctly.
3. Water Valves: Test each valve (one to four may be installed) for proper operation.
4. Pump: Ensure the pump is effectively pumping out water.
5. Enter Diagnostic Mode: For this model, press the third and fourth buttons, then the on/off button.

Replacing the Main Motherboard

Once we've identified the motherboard as the problem, the next step is to replace this component. You can follow the steps below to replace your PCB perfectly:

1. Power Off and Unplug: Ensure the machine is completely powered off and unplugged.
2. Remove the Lid: Unscrew the lid to access the internal components.
3. Remove the Control Panel:

• Unscrew the top four screws on the facial board.
• Remove the soap drawer and the two screws inside it.
• Remove any screws holding the control panel.

4. Photograph the Wiring: Take photos to ensure you can reconnect everything correctly.
5. Disconnect the Wires: Carefully remove all connectors from the control panel.
6. Remove the Circuit Board:

• Unscrew the circuit board.
• Release the catches on each side to lift it out.

7. Install the New Circuit Board:

• Insert the new board, ensuring it aligns with the lugs.
• Secure it with screws.
• Reconnect all wires as per your photographs.

8. Reassemble the Machine:

• Replace the control panel, ensuring all connections are secure.
• Reattach the lid and any other components.

Finding a Replacement Circuit Board

When replacing the motherboard, it's crucial to check all other components in the machine before making any changes.

Buying a parts from the manufacturer can sometimes cost nearly as much as a new machine. It seems ludicrous to spend so much when we're striving for a more environmentally friendly approach to our appliances.

Thankfully, manufacturers are now being held accountable by governments through the right to repair act. This act emphasizes the need to manufacture machines that can be affordably maintained and repaired in the future. Unfortunately, parts like the motherboard can often be prohibitively expensive to replace.

We gave a useful life hack about how to buy any spare parts for your appliance from online channels, so it is worth watching for you to fully understand how to buy spare parts without spending too much money on them.

In summary, we provide a comprehensive overview of how to diagnose and repair a recurring problem in Samsung WW80J555FX/EU washing machines. It covers everything from identifying the problem, diagnosing the fault, replacing the main motherboard, and finding a cost-effective replacement circuit board.
