This document serves as a service manual for Teka dryer models TKS1 710 C and TKS 850 C, identified by the manual number MSWM15031 EN. It provides essential information for technicians, covering the appliance's functionality, control panel operation, service test procedures, error code interpretations, wiring diagrams, and component testing specifications.

Function Description:

The Teka TKS1 710 C and TKS 850 C are clothes dryers designed to remove moisture from laundry. They offer a range of drying programs and features to accommodate different fabric types and user preferences. The core function involves heating air and circulating it through a drum containing wet clothes, then expelling the moist air. Key components facilitating this process include a motor for drum rotation, a dryer heater for air heating, a drain pump for water removal, and various sensors to monitor temperature, humidity, and water levels, ensuring efficient and safe operation.

Usage Features:

Both models feature a control panel that allows users to select drying programs and adjust settings.

TKS1 710 C Control Panel:
- Program Knob (4): Used to select different drying cycles.
- Start/Pause Button (1): Initiates or pauses the selected program.
- Anti-Crease Button (2): Likely adds an anti-crease phase to the drying cycle, reducing wrinkles.
- Gentle Button (3): Suggests a gentler drying option for delicate fabrics.
- ON/OFF Button (5): Powers the appliance on or off.
- Delay Button (6): Allows users to set a delayed start time for the drying cycle.
- Time Button (7): Likely for adjusting the drying time manually or for specific timed programs.
- Display: Shows program information, remaining time, and error codes.
- Indicators: Includes lights for Drying, Ironing, Normal, Airing, Child Lock, Warm, Cool, Quick, Anti-Crease, and Gentle settings.
TKS 850 C Control Panel:
- Program Knob (1): Selects drying programs, with options like "especial," "algodón" (cotton), "favoritos" (favorites), "vaqueros" (jeans), "mixto" (mixed), "ropa deportiva" (sportswear), "camisetas T" (T-shirts), "calentar" (warm), "enfriar" (cool), "ventilar" (ventilate), and "tiempo" (time).
- Display (2): A digital display showing program status, time, and error messages. It also indicates "Filter Full."
- Function Buttons (3): Additional buttons for specific functions, possibly including "diferido" (delayed start), "tiempo" (time), "intensidad luz" (light intensity), "volumen" (volume), and "bloqueo" (lock).
- Start/Pause Button (4): To start or pause the drying cycle.
- ON/OFF Button (5): To power the appliance on or off.
- Indicators: Includes icons for various programs and settings like "algodón plancha" (cotton iron), "delicado" (delicate), "sintético" (synthetics), "sintético plancha" (synthetics iron), and "lana" (wool).

Both models incorporate a "Child Lock" feature, enhancing safety by preventing unintended operation.

Maintenance Features:

The service manual outlines procedures and specifications crucial for diagnosing and repairing the dryers.

Service Test:
- Access: To enter the service test, the dryer must be switched off. Press and hold the "delay" [6] and "time" [7] buttons (TKS1 710 C) or "volume" button (TKS 850 C) simultaneously, then switch on the appliance using the ON/OFF button. The display will show "LSE."
- Initiation: Press the "gentle" button [3] (TKS1 710 C) or "volume" button (TKS 850 C) to start the test.
- Test Phases: The service test progresses through several phases, each checking specific components:
  - L01: Motor spinning.
  - L02: Motor spinning + dryer heater (700 W).
  - L03: Motor spinning + dryer heater (1800 W) + water level sensor.
  - L04: Motor spinning + drain pump.
  - End: Service test is ended.
- Water Level Sensor Check (L03): This phase specifically checks the water level sensor. If water is not detected, the test will stop, and "E00" will be displayed. To proceed, approximately 0.6 liters of water must be poured into the upper drawer to simulate an overflow, allowing the test to verify the sensor's function.
Error Codes: The manual provides a list of error codes and their probable causes, aiding in troubleshooting:
- E30: Dryer heater failure (Check thermal, dryer heater).
- E32: Humidity sensor failure (Check humidity sensor).
- E33: Inlet air sensor failure (Check inner air sensor).
- E34: Outlet air sensor failure (Check outlet air sensor).
- E60: Motor failure (Check winding for the motor).
Connections and Wiring Diagram: A detailed wiring diagram is provided, illustrating the connections between the PCB (Printed Circuit Board) and various components. This diagram is essential for tracing electrical paths and identifying faulty connections. Key connections include:
- CN2, CN3, CN4, CN5, CN6, CN11, K3, K4: Connectors on the PCB.
- Components: Pump, Lamp, Door Switch, Humidity Sensor, Power Cord, Filter, Motor, Capacitor, Heater, Inlet Temp. Sensor, Water Sensor, and Outlet Temp. Sensor.
Components Testing: The manual specifies expected measurements for key components, allowing technicians to verify their functionality using a multimeter:
- Dryer Temperature Sensor: Resistance varies with temperature:
  - 5°C: 12KΩ
  - 10°C: 9.5KΩ
  - 15°C: 7.5KΩ
  - 20°C: 6KΩ
  - 25°C: 4.8KΩ
  - 30°C: 3.9KΩ
  - 35°C: 3.1KΩ
- Heater Sensor: 15°C ~ 65KΩ.
- Motor Capacitor: 7.5 uF ±10%.
- Drain Pump:
  - Voltage: 220 - 240 V.
  - Windings: ≈0.78KΩ±10%.
- Motor:
  - Supply voltage: 220 - 240 V.
  - Main winding (Green-Orange): ≈250±10%.
  - Secondary winding (Red-Orange): ≈250±10%.

These specifications are critical for diagnosing component failures and ensuring proper repair and maintenance of the Teka TKS1 710 C and TKS 850 C dryers.
