Need help?Do you have a question about the Samsung DV203 SERIES and is the answer not in the manual?
This document provides a comprehensive guide for troubleshooting, maintaining, and understanding the operation of Samsung dryers, specifically models DV203***, DV206***, DV209***, DV218***, DV219***, DV306***, DV316***, DV317***, DV326***, DV328***, DV337***, DV338***, and DV3C6***. It is intended for technicians with electrical, electronic, and mechanical experience, emphasizing safety and proper repair procedures.
The core function of these Samsung dryers is to efficiently dry clothes. They incorporate various features to ensure effective and safe operation, including a diagnostic system that helps identify and resolve common issues. The diagnostic codes, displayed on the dryer's interface, provide quick insights into potential problems. For instance, an "Error! Temperature Sensor Problem" indicates a thermistor issue, which could be either a short (very low resistance) or an open circuit (very high resistance). In such cases, the recommended actions involve checking for a clogged lint screen, a restricted vent system, and the thermistor's resistance.
Another common diagnostic code is "do" with "Error! Door is open," which signifies that the dryer is running with the door open. The solution involves checking for loose or open wire terminals in the Door Sense circuit. Similarly, "FE" with "Error! Power Interruption Error" points to an invalid power source frequency, requiring a check for a non-utility power supply. A "dF" error, indicating a "Door Open Sensing Problem" or "Door Circuit Failure," suggests an invalid state for more than 256 milliseconds, prompting a check of the door sense circuit's wire terminals. The "hE" or "HE" error, labeled "Heater Error" or "Overheated," indicates an invalid heating temperature during operation, necessitating a check for a restricted vent system and thermistor resistance. Finally, a "bE" error, or "Button Error," signifies a button stuck or continuously pressed for 75 seconds, requiring an inspection of the Display PCB for a stuck button.
Beyond basic operation, the manual details several test modes designed to assist technicians in diagnosing specific components and functions. The "Cycle Count Test Mode" allows technicians to access cycle data by pressing specific key combinations during the Power On State. The "Temperature Test Diagnostic Mode" enables the display of the temperature in Celsius, facilitating a comparison between vent and drum temperatures to assess airflow. This mode is activated by pressing the Signal + Wrinkle Prevent Keys for 3 seconds, followed by Time + Wrinkle Prevent Keys.
The "Sensor Bar Touch Data Mode" is useful for checking the functionality of the moisture sensors. In this mode, after starting the dryer tumbling and pressing Temp + Signal for 3 seconds, opening the door and touching both sensor bars with a wet cloth should display numbers, indicating proper sensor operation. The "Software Version Test Mode" allows technicians to view the dryer's software version by pressing Signal + Wrinkle Prevent Keys for 3 seconds, followed by the Temp key for 3 seconds.
A "Special Test Mode" is also available, initiated by simultaneously pressing the Dryness Level + Power keys while the dryer is in the Power Off state. This mode, indicated by "t2" on the display, progresses through a system check sequence, including motor and heater relay operations. Technicians are cautioned not to prolong this test mode to avoid over-burdening the Main PCB.
Maintenance features are also highlighted, particularly regarding the gas valve and thermistor. The "Gas Valve Testing" section provides instructions for unplugging connectors and testing valve terminals, specifying resistance values for the Booster Coil (550 Ω), Holding Coil (1350 Ω), both coils in series (1900 Ω), and Secondary Coil (1300 Ω). This ensures proper functioning of the gas supply system in gas dryer models.
The thermistor, a critical component for temperature regulation, has a detailed resistance chart provided. This chart correlates temperature in Fahrenheit with corresponding resistance values in Ohms, allowing technicians to verify the thermistor's accuracy. For example, at 77°F, the thermistor should read 10KΩ, and at 200°F, it should read 850Ω. This information is crucial for diagnosing temperature-related issues.
The document also provides important safety guidelines, particularly concerning the types of substances that should not be dried. It explicitly warns against drying clothes with traces of flammable substances such as vegetable oil, cooking oil, machine oil, flammable chemicals, thinner, wax, or chemicals found in mops and cleaning cloths, as these can cause fabric to catch fire.
Regarding installation, the manual specifies electrical requirements for both electrical and gas dryers. Electrical dryers require 240 VAC, 60 Hz, 30 Amps, with either 3-wire or 4-wire installations. Gas dryers require 120 VAC, 60 Hz, 15 Amps, with 3-wire installations. Location considerations in the USA mandate that all dryers must be vented to the outside, and only rigid or flexible metal duct should be used for venting. The document also provides detailed guidelines for weather hood types and vent length restrictions based on the number of 90° elbows in the ductwork, differentiating between rigid and metallic flexible ducts for both recommended and short-run installations. For instance, with no elbows, a rigid duct can extend up to 24.4 meters (80 ft) for recommended use, while a metallic flexible duct is limited to 12.4 meters (41 ft).
Finally, the "Wrinkle Prevent" option is described as a usage feature that provides approximately 90 minutes of intermittent tumbling in unheated air at the end of the cycle to reduce wrinkling. This feature is activated by pressing the Wrinkle Prevent button, which illuminates an indicator light and displays chasing lights on the interface. This allows users to remove clothes at their convenience while minimizing wrinkles.
