Error 4C on a Samsung dishwasher

It’s possible that you have seen the 4C error code on your Samsung dishwasher’s display. This code can be annoying, particularly if you’re trying to finish the dishes in the middle of a hectic day. Don’t worry, though; figuring out what this error means and how to fix it can be fairly easy.

On a Samsung dishwasher, the 4C error denotes a water supply issue. This typically occurs when there is insufficient or no water flowing to the dishwasher. A kinked hose, a clogged filter, or a malfunctioning water inlet valve are a few possible causes of the problem. It can also occasionally happen if your home’s water pressure is too low.

There are a few steps you can try to take care of the problem yourself before calling a technician. Often, the issue can be resolved by inspecting the water supply lines, making sure the hose is not twisted, and cleaning any filters. You might be able to fix your dishwasher without hiring a professional if you do a little troubleshooting.

Water is not supplied to the dishwasher

Although it may seem insignificant, issues with the water supply are frequently the cause of the Samsung dishwasher’s lack of water supply. As a result, wait to call a repairman if the aforementioned error code shows up on your display before making sure the house is dry.

It’s important to check the tee tap, which is required to cut off the liquid supply to the household appliance, in addition to the water pressure needed for the dishwasher. The tap’s shut-off lever frequently breaks off inside, which explains why the device is broken but appears to be fully functional. This means that turning in any direction won’t make a difference and the mechanism will stay blocked. Given that the tee tap appears to be in perfect condition, it makes sense that the Samsung dishwasher would be the object of initial suspicion in this case.

You must proceed to more involved testing phases if the issue is not with the tee tap or the water supply. Do not be afraid of repairs because the majority of the causes are easily fixed at home, even without specialized knowledge.

Which part does not allow water to pass through?

When the Samsung dishwasher displays the 4C error message, but the tee tap is in good working order, there is water in the house, and all of the "home assistant’s" operating guidelines have been followed, it is wise to begin a gradual inspection of the equipment’s major parts, beginning with the most likely culprits. Experts have identified the following conditions that could result in this error code appearing.

• The flow filter or the entire PMM system is clogged.
• The inlet valve is broken, blocking the liquid supply.
• The door of the washing chamber is faulty, so the user cannot hermetically close the household appliance.
• The water level sensor is broken.
• The protective mechanism "Aqua Safe" has been triggered.
• The control module of the Samsung dishwasher is damaged.

Since there aren’t many choices, you can reset the 4C error and find the malfunction by carefully going over each point.

Aqua Safe

You should begin by using the hose that has the "Aqua Safe" leak protection system installed. The device resembles a tiny valve that can stop flooding in the event that the hose leaks. Should this truly occur, it would be best to replace the sleeve entirely rather than attempting to patch it. Determining that the hose is the source of the issue is simple. The hose indicator at the water supply connection section will turn red if it is obstructed. How should the element be replaced?

• Disconnect the Samsung dishwasher from all utilities.
• Remove the leaking hose.

Make sure to cover the floors with rags or extra towels before making repairs to prevent the floors from becoming flooded with hose water.

• Install the new hose in its seat and carefully tighten it, without using an adjustable wrench or other special tools, as this can damage the fragile plastic nuts.

Connecting the apparatus back to the water and light after all the adjustments is necessary to inspect it during a test work cycle. Make sure that all of the nuts are tightened and that there are no leaks by keeping a close eye on the hose using the "Aqua Safe" system.

Finding and eliminating the blockage of the flow filter

If the above suggestion was ineffective in resolving the issue, low-quality tap water may have been the cause of the malfunction. Because hard tap water with a variety of impurities is typical in Russia, the Samsung dishwasher’s filter can clog easily. In the event that this occurs, the liquid will either fill completely or very slowly.

The flow filter itself is very easy to locate; it resembles a tiny mesh that aids in the retention of different contaminants and abrasive particles. Without this filter, particles from the water supply would enter the dishwasher directly and harm some of its most important parts. How should a clogged filter be cleaned?

• Disconnect the dishwasher from the water supply.
• Remove the water supply hose.
• Find the mesh that is installed at the junction of the hose with the dishwasher.
• Clean the mesh with a needle or pin, pulling out the smallest contaminants from it.
• Additionally rinse the debris filter under running hot water.

Should the item become stuck to the dirt, it is necessary to immerse it in a solution containing citric acid for a minimum of sixty minutes.

Place the cleaned component back in its designated spot. Make sure you test the Samsung dishwasher to determine whether the issue has been resolved.

The water inlet valve is broken

Replacing the water inlet valve might be able to resolve the 4C error if it hasn’t gone away yet. It will simply stop opening even after receiving a signal from the Samsung dishwasher control board if it is out of order, so there won’t be a liquid inlet. Generally, operating in unfavorable conditions—such as persistently abrupt voltage drops or fluctuations in liquid pressure—is linked to damage to the valve.

Don’t attempt to fix the part if it is truly out of commission. Should you feel confident in your skills, purchase a new valve, install it, and test the machine’s operation using the deformed part as an example. If you are not confident in your ability to disassemble the "home assistant" partially, it is best to call a repairman for a replacement as this is a fairly involved and time-consuming procedure.

When a Samsung dishwasher displays error 4C, there is likely a problem with the water supply, which could be caused by low water pressure or insufficient water supply. A closed water valve, a kinked or clogged water hose, or a blocked inlet filter are a few possible causes of this error. In order to fix the problem, it is usually necessary to inspect these components for damage or obstructions and confirm that the dishwasher’s water supply is fully open and operating as intended. We’ll go over the typical causes of Error 4C in this post and show you how to fix them so your dishwasher functions properly once more.

No signal from the pressure switch

Replacing the pressure switch is another way you can attempt to resolve the error code. The dishwasher control module may receive inaccurate or no data at all from the water level sensor, or it may stop sending information about the liquid level. To avoid unintentionally flooding everything around the dishwasher, the control module will simply stop filling with water in this scenario as it is unable to determine the best course of action. In the event that you have a standard multimeter at home, you can use it to test whether the pressure switch is operating normally.

• Disconnect the Samsung dishwasher from communications.
• Put the appliance on its side.
• Remove the lid from the bottom of the dishwasher.
• Find the water level sensor – it looks like a plastic washer.
• Carefully remove the tube from the pressure switch.
• Carefully remove the element clamps, remove the wires, and then the water level sensor itself.

To have a reference later on, it is preferable to take multiple pictures of the wires connected correctly.

• Set the tester to ohmmeter mode, connect its probes to the pressure switch contacts and measure the resistance.

The only way to completely resolve the 4C error is to replace the sensor; you should not attempt to fix a damaged unit.

When a Samsung dishwasher displays error 4C, the water supply is likely the issue. A kinked or clogged water hose, a blocked water inlet filter, or a problem with the water supply valve itself are some of the possible causes of this error. To make sure that water is getting to the dishwasher properly, it is imperative to inspect these parts.

In order to fix this error, you should first make sure the water hose is connected correctly and check it for bends or obstructions. Additionally, look for any debris that might be obstructing water flow in the inlet filter. Resolving the issue and restarting your dishwasher can often be achieved by cleaning or replacing these parts.

In certain instances, the issue may be more complicated and involve a broken water supply valve or the dishwasher’s internal water level sensor. For a more comprehensive diagnosis and repair, you might need to speak with a qualified technician if basic checks and adjustments are insufficient to fix the issue. Recall that fixing the 4C error right away can help shield your appliance from additional harm and save you money on future, expensive repairs.
