MODEL OVERVIEW
About this model: Samsung WF45R6300AV/US
Samsung's Canadian support record identifies WF45R6300AV/US as a smart front-load washer with SuperSpeed and links a 212-page owner document.
Confirm that the 6300R instructions belong to this washer
Samsung's Canadian support record identifies WF45R6300AV/US as a smart front-load washer with SuperSpeed and links a 212-page owner document. The cover of that PDF says WF45R6300A*, which is the model family, while the support record supplies the exact AV/US suffix. That link is the reason to apply its information-code tables to this washer. The support heading says 5.2 cubic feet; the manual's physical page 60 prints 4.5 cubic feet for the WF45R6300A* specification and also gives a 900-watt heating rating. Keep those values attached to their respective Samsung sources rather than merging them into a single unexplained figure. The 6300R panel uses a cycle selector and discrete option buttons, and the manual tells owners that an information code appears when the washer needs checking. A code guide for a newer 6300B interface may look familiar yet describe a different revision.
Use the panel's shortcuts with their stated limits
The owner explains several controls that can be confused with faults if their behavior is overlooked. Holding Spin for three seconds requests Spin Only. Delay End shows the hour at which the wash will finish, not the time at which it begins. Child Lock can keep controls unavailable; the instructions distinguish a three-second activation from a six-second cancellation using Temp. and Rinse. The Cold temperature level one uses only cold water and does not engage the heater, even though this family has a heating element for other selections. Quick Wash is recommended for loads of four pounds or less. The downloaded cycle comes through SmartThings after the washer is connected to the home network, and Smart Control requires that connection. These details help reconstruct what happened before a code: note the chosen cycle, options, load size and whether the door was locked during heating before interpreting a stopped programme as a broken part.
Investigate the supply and drain paths separately
Page 20 gives a water-pressure range of 20 to 116 psi, while the installation instructions put the drain system between 18 and 96 inches above the floor. These are useful reference points when the washer does not fill or empty as expected. A 4C directs attention toward the inlet side: confirm the taps are open, the hoses are not kinked and the small mesh screens are clear. 4C2 narrows the issue to water that is too hot, so verify the hot and cold connections. A 5C instead concerns the outlet route. Check the hose and the front pump filter, then follow the owner's emergency-drain steps to catch water before opening that filter. Samsung documents separate mesh-filter and pump-filter care; cleaning one is not a complete response to both codes. LC raises a leak concern, and OC warns of possible overflow. Close the supply valve and seek service for OC as the table directs.
Match each remaining code to its printed system
The information tables on physical pages 56 and 57 contain eighteen literal codes. DC means the door is open and DC1 asks for a door-switch check. UB concerns spin balance: redistribute the load and verify the appliance is level before assuming a motor fault. HC calls for a washing-heater check and is consistent with the 900-watt heating specification on page 60. The 1C row names the water-level sensor; 8C, 8C1 and 8C2 concern the MEMS sensor; 3C refers to the motor; AC6 concerns control-board communication; and 9C1 or 9C2 asks for an electronic-control check. SF indicates a system failure. These rows have different remedies. The manual allows a power-off wait of two or three minutes for some conditions but directs service for persistent or particular faults. Preserve the exact character sequence; DC1 and DC are different entries, as are 4C and 4C2.
Record the evidence before a controlled retry
Smart Care can analyze a displayed information code with the phone camera; the owner also allows manual code entry if recognition fails. Record the code and cycle phase first, because a restart can remove the display. If a power failure leaves water in the drum, the emergency-drain procedure provides an owner-level way to release it before dealing with the door. The Self Clean reminder after forty cycles is maintenance information rather than a fault. For a code with an explicit retry instruction, switch off, wait as directed and make one controlled attempt. Do not keep restarting a machine that is leaking or overflowing. If the same entry returns, or the row says to contact service, give Samsung WF45R6300AV/US, the exact code and the linked manual revision. This lets a technician distinguish a water-path issue from a sensor or control problem without guessing from the washer's appearance.
