Samsung washer shows 3 LEDs in the form of continuous burning opposite the water temperature (cold, 30, 40 degrees) and the flashing of lamps in the washing modes. In this case, the machine neither starts the program nor drains.
What does LC error code mean?
The error is associated with a malfunction of the pressure switch. It sends signals to the electronics when the tank is full but if damaged, the signal will not reach the control. It is time to proceed to the next action. But in case of damage, the signal will be distorted or will not reach the control board, therefore, resulting in error code LC.
How to solve the problem yourself?
First, restart the washing machine:
- Switch off the power (disconnect the cord from the mains);
- wait 5-10 minutes;
- connect the equipment into the network.
If the error is resolved, it was an accidental failure of the controller. If the error still appears, check the contacts and the connectors.
To eradicate the error, replace the pressure switch, or blow the tubes to remove clogs that block various valves, pipes, hoses, etc.
What needs to be fixed so that the LC error disappears?
If all else fails and LC I still displayed, then take other drastic measures. However, note that the main cause of the error is a faulty pressure switch and due to this, major efforts have to be directed towards replacing or repairing it.
The pressure sensor is out of order
If the pressure switch cannot determine the water level correctly and does not cope with its function effectively, specialists recommend that it be replaced with a new one. Repairing it is nearly impossible and could end up costing more than replacement.
The control board is damaged
The control board may be affected by detergent, splashes of water, and condensation. Also, unseen incidents such as accidental falls may shot electronic circuit elements. All these causes the error code LC. The error will be resolved by repairing the tracks, clean the oxidized contacts, and re-solder the defective parts. If the control module is completely damaged, replace it with a new one.
Break-in internal wiring
Start by inspecting the wiring harness. It can be done visually or using a multimeter if it was not possible to define a problem segment. If wires are broken or burned, solder, twist, and insulate them. This normalizes the signal permeability. In severe scenarios replace the whole tourniquet.
