Error dC, dC1, dC2 in Samsung washing machine

You conceived the wash, habitually loaded things into the drum, poured in the detergent, closed the door and pressed “Start”. But nothing happened: no water is drawn into the machine, and the dC error is on the display of your Samsung. You may not have heard the traditional click when the sunroof lock is activated.

Occasionally, housewives contact the RemBytTekh service, whose washing machine issued a dC code during the washing process. This can happen at any stage of program execution. Washing at the same time stops, the cycle is interrupted.

What does the dC error code mean

With the code dC (it is also possible to write dC1, dC2), the Samsung washing machine reports that there are problems with the door lock. The hatch doesn’t lock. And since through the UBL (hatch blocking device) the current goes to all other SMA nodes, the wash does not start or is interrupted.

What can you do yourself

The dC code does not always indicate a breakdown. Before contacting the workshop, check the following reasons.

• Is the door tightly closed? Open and close it again until a characteristic click.
• Have you pinched something with the sunroof. Perhaps a lone sock or sleeve of a sweater is stuck between the hatch and the rubber cuff and is preventing the door from closing tightly. Open the hatch, straighten the laundry and close the door again.
• Is the control board stuck? Sometimes the control units of the washers “freeze”. Requires an overload. To do this, disconnect the CMA from the mains by pulling the plug out of the socket for 10-15 minutes. If, after turning on the Samsung machine, it began to work without any errors, it was a one-time board failure, and you successfully dealt with it. The situation is unlikely to happen again, and you do not need to call the wizard.

If none of the options above match your situation, and the Samsung machine still gives an error, there is probably a breakdown.

Possible malfunctions requiring repair

According to the experience of the RemBytTekh workshop, whose specialists have repaired thousands of Samsung washing machines, the following breakdowns most often lead to an error with the dC code.

Breakdown of UBL (hatch blocking device)

UBL – locking device. Inside the node there is a thermal tablet and a bimetallic plate. When you start washing, voltage is applied to the thermal tablet, it heats up and transfers heat to the plate. In turn, from heating, the bimetallic plate bends, presses the latch, it enters the groove, and the lock locks the hatch. Over time, the coating of the thermal tablet burns, and the tablet itself is destroyed. Less commonly, a bimetallic plate loses its flexibility. As a result, the latch remains motionless, the door does not lock, the wash does not start, and the machine generates a dC error.

UBL malfunction is the most common cause of the dC code in Samsung.

signs

The machine does not lock the door when the cycle starts and does not start the wash. The display shows error dC. For the first time, this error can occur at any stage of program execution.

How to eliminate

UBL cannot be repaired, the unit is replaced with a new one.

The control unit is out of order

The control unit is an electronic board. All programs of the washing machine are “sewn” into it. Like all electronics, the board is sensitive to moisture and power surges: for this reason, individual radio elements, contacts or tracks can burn out on it. If a dC code appears, most likely a malfunction has occurred in the sunroof lock circuit. For example, in the UBL relay.

signs

The Samsung machine does not block the sunroof when the program starts. The display shows error dC.

How to eliminate

The master diagnoses the control module. Faulty radio elements (relays, triacs, resistors, etc.) are replaced with new ones. If the contacts of the elements and / or tracks are burned out or oxidized, the master solders them.

In case of extensive damage to the board (for example, the processor or many radio elements burned out), the control unit is replaced with a new one.

Mechanical damage to the lock

When closing the SMA, the locking hook falls into the lock window. It contains a plastic guide plate. Normally, the hook moves the plate. When you start washing, voltage comes to the UBL, the thermal tablet heats up the bimetallic plate, it bends and presses on the plastic tongue. He is in a special hole in the guide plate and fixes it in place. This is how the hatch is blocked.

If the guide plate is damaged or deformed due to careless use, the lock will not lock and the door will not lock.

signs

The Samsung washing machine does not fix the door: when closing, the traditional click is not heard. The display shows the dC code.

How to eliminate

Locks for washing machines are sold only as an assembly, so the master replaces the entire assembly with a new one.

Damaged contacts or wiring in the UBL circuit

UBL has three contacts: two of them fall on the lock, the third terminal closes with one of the first two when the lock is locked. Often, the contacts burn or oxidize in the blocking device itself. Especially if water or rubbish got into it.

Another option: damage to the contacts or wiring in the UBL circuit in the area from the control module to the lock or chafing of the cable in the area from the SMA body to the hatch.

signs

Samsung washing machine does not block the door. A dC error appeared on the screen.

How to eliminate

The master is looking for a signal break. If the reason is in the UBL contacts, the assembly is replaced with a new assembly. If the loop is damaged, the master restores the wiring or changes the entire loop.
