You’re not the only one whose washing machine suddenly shows a 4C fault number. Samsung washing machines are the most likely to display this error, although it may also occur in models from other brands, including Bosch, LG, Siemens, and Whirlpool. The 4C code typically indicates that the washer isn’t receiving enough water. This might be because the filters are clogged, the hoses are kinked, the water pressure is low, or the control board is broken.
At Al Karama Technical LLC, we are experts in identifying and resolving these types of issues. Our crew has the equipment and expertise to repair your Samsung washing machine near you, Bosch washing machine in Dubai, or LG washing machine control board quickly and effectively.
Let’s review the seven steps you need to take to resolve the washer error code 4C, which applies to all major manufacturers.
Step 1: Make sure the water valves are open.
Ensure that both the hot and cold water supply valves are fully open before proceeding. Some washers, such as newer Samsung or Siemens units, require both valves to be open for the unit to function correctly. The machine may give the 4C error if one valve is closed.
People in Al Quoz, Al Barsha, or International City often contact our professionals for Washing Machine Repair Al Quoz or Washing Machine Repair International City, particularly when they notice that the water flow is not steady. In most cases, a simple adjustment to the valve fixes the problem.
Step 2: Examine the hoses that supply water.
Blocked or bent intake hoses are the second most prevalent cause of the 4C code. Remove the hoses from the rear of the washer and inspect them closely. If there is a lot of dirt on the hoses, clean them well. If they are bent, replace them.
Our Samsung Washing Machine Repair and Zanussi Washing Machine Repair services in Dubai can repair or clean these hoses for washers from Samsung, LG, or Zanussi.
If you live in Discovery Gardens, our fast and efficient service staff can help you with washing machine repair in Dubai Discovery Gardens to find the problem and fix it quickly.
Step 3: Clean or Change the Mesh Filters
There are little mesh filters within the connections for the intake valve. These capture dirt and debris from the water supply, but they may become blocked over time. The 4C error number indicates that a clogged mesh filter is blocking the water flow.
Use needle-nose pliers to remove the filters carefully. Then, under running water, clean them with a brush and put them back on. We recommend replacing them if they break, especially for high-efficiency washers from Bosch, Panasonic, and Haier.
We provide expert Panasonic and Haier washing machine repair manuals to ensure that the mesh filters and all other parts inside are clean and functioning correctly.
Step 4: Check the water pressure at the inlet
We have observed that buildings in several areas, such as Al Qusais and Al Nahda, have poor water pressure. This is another big reason for the 4C mistake, especially in Samsung and LG washers.
Check the supply using a water pressure gauge. You may need to add a booster pump if the measurement is lower than the required pressure.

As part of our washing machine repair services in Al Qusais and Dubai Al Nahda, we regularly check the water pressure to ensure optimal performance. Our professionals will suggest a long-lasting solution, such as replacing a valve or increasing the pressure.
Step 5: Check the lock on the washer door or lid.
A broken door or lid lock may sometimes cause a 4C error code, especially in top-load washers. For safety concerns, the washer will cease taking in water if it doesn’t find a secure lock.
Ensure the latch clicks and the door or lid closes completely. If the latch isn’t lined up well or the door sensor is malfunctioning, you may need to repair certain parts. We have genuine parts for Amana Washing Machine Repair, Aftron Washing Machine Repair, and more at Al Karama Technical LLC.
People commonly want us to repair their washing machines quickly, and we do it well.
Step 6: Reset the system
A quick reset may resolve minor software or sensor issues. To accomplish this:
Unplug the washer, wait 5 to 10 minutes, and then plug it back in. To determine whether the 4C fault has been resolved, run a test cycle. This approach works well with models made by AEG, Siemens, and LG.
If the problem persists, we recommend contacting our Siemens Washing Machine Repair Dubai or AEG Washing Machine Repairs experts for a more thorough examination.
Step 7: Identify the issue with the main control board (PCB) and make the necessary repairs.
If none of the preceding methods work, the problem might be with the control board (PCB). A broken PCB may be unable to detect the amount of water in the system, provide incorrect readings, or cease functioning in the middle of a cycle.
This type of problem occurs frequently with older Whirlpool and Hitachi units. We fix washing machines by replacing or repairing the control board. We can do this for most manufacturers, including Whirlpool, Hitachi, and Ariston, as well as washing machines in Dubai.
If you need Bosch washing machine repairs near you, we are the best place to go for speedy PCB diagnosis in Dubai Marina, Discovery Gardens, and International City.
