Question 2

What does error code 3C mean on Samsung WA50M7450AP?

Accepted Answer

The washer's motor can't spin properly. Cause: Motor spin net is not engaged; Motor internal coil is damaged (short-circuited or cut); Hall sensor terminal is not connected; Foreign material (a screw) has entered the motor; Motor overloaded due to too much laundry; Motor hall sensor terminal is not connected; Main PBA fault; Motor driving error from the PBA (weak signal); Unstable relay operation; Erroneous operating signals from the motor hall sensor; IPM terminal of the main PBA is not connected; DD motor cover is out of place; PCB housing terminal is not connected; DD motor fault.

Question 3

What does error code 4C mean on Samsung WA50M7450AP?

Accepted Answer

The washer isn't getting water when it needs it. Cause: Foreign material entering the water supply valve; Water supply valve terminal is not connected (wire disconnected); Warm water and rinse connectors are wrongly connected to each other; PCB terminal from the drain hose to the detergent drawer is not connected; Transparent hose is folded or torn; Cold and warm water supply hoses are wrongly engaged into each other; Main PBA fault; Water supply blocked due to alien substance in the valve; Frozen water supply.

Question 4

What does error code 4C2 mean on Samsung WA50M7450AP?

Accepted Answer

The incoming water is too hot for the selected cycle. Cause: Water temperature supplied through the dry valve during drying cycle exceeds 70°C; Water temperature sensed as higher than 50°C in Wool or Lingerie courses; Hot water supply connected to cold water inlet; Water heater set too high.

Question 5
