This document serves as a service manual for Ariston Electromechanical Vented Tumble Dryers, specifically covering the TVM63X NA model. It provides essential information for qualified technicians regarding the appliance's function, operation, and maintenance.
The tumble dryer operates by drawing cold air into the cabinet through louvres in the base. This air then passes through a large hole in the inner back panel, driven by a fan, and is directed through the element housing. After being heated by the element windings, the warm air enters the drum through holes in the drum back plate. Inside the drum, the warm air circulates through the load, extracting moisture from the damp fabric. A webbing seal on the inner back panel prevents warm air from escaping into the cabinet interior.
As the drum revolves, the clothes are tumbled through this warm air stream. The now moist and cooled air then passes through a filter located in the air duct on the back of the front panel, where lint and fluff are removed. Finally, the air travels through the front-to-rear air duct and exits the dryer at the rear outlet. A vent hose can be attached to this outlet to direct exhaust air away from the dryer.
The heating system incorporates safety features. A cut-out on the element housing interrupts the Live electricity supply to the element if the air temperature becomes too high, typically due to restricted airflow (e.g., a blocked filter). This cut-out automatically resets once the air temperature drops to an acceptable level and will cycle if the fault persists. A secondary 'one-shot' cut-out, positioned alongside the 'auto reset' cut-out, acts as a safety device to break the element Neutral connection if the air temperature reaches an unsafe level due to a failure of the 'auto reset' cut-out.
Two thermostats are located in the front air duct. Depending on the selected program, only one is active at a time. These thermostats sense the exhaust temperature rise as the load dries, and when the clothes are dry, they energize the timer motor on the main timer, allowing it to advance to the cool run phase.
The dryer offers various drying programs and heat settings, controlled via a console panel. The console includes a timer knob for selecting timed and sensed drying periods, and a push switch for heat selection.
The Timer 1 (Programme Timer), mounted on the console, controls the motor and heating during drying programs. It features a timed cycle of up to 170 minutes of heated drying, followed by a 7.5-minute cool run. An 'Eco' program is available, which provides heated drying until a thermostat operates (indicating the load is dry), after which the timer advances to a 7.5-minute cool run. The cam of this timer pauses on the heated part of the cycle by cutting the circuit to its motor. The dryer motor continues to reverse, controlled by Timer 2. When the load is dry, a front duct thermostat powers Timer 1's motor, allowing it to advance to cool run. An optional crease removal program is also provided, consisting of 7.5 minutes of heat and motor operation, followed by a 2.5-minute cool tumble.
The Timer 2 (Reversing Timer), mounted on the base panel, controls the motor's reversal during drying programs, changing direction approximately every 2.5 minutes.
The Heat Switch is a normally open push-push switch on the facia moulding, allowing users to select high or low heat settings. Operating this switch selects either all or half of the heater unit. The 'IN' position corresponds to full heat, and the 'OUT' position to low heat. For automatic drying programs to function correctly, high heat must be selected; otherwise, the dryer will advance to cool run without drying the load.
The START button initiates the selected program. The HEAT button selects the drying temperature. The Drying Guide on the console provides a user-friendly table of fabric types, load capacities, and available programs. The TIMER / PROGRAMMES knob sets the drying time or program. It should always be rotated clockwise, never anti-clockwise, until the indicator points to the desired time or program.
Automatic Drying requires the high heat setting to be enabled and is optimized for cotton loads between 3 Kg and 6 Kg. Using automatic drying for smaller or delicate loads may yield erratic results. The automatic drying sequence begins with 20 minutes of full heat, controlled by the timer, to pre-heat the clothes and drum. The timer then advances to its next cam position, disconnecting the timer motor while the dryer continues to tumble and heat. When the clothes are dry, the exhaust thermostat opens, providing a Live supply to the timer motor, which then advances the timer to the next cam position. This is followed by 5 minutes of tumbling with only the lower element, and finally 7.5 minutes of tumbling with no heat.
The Easy Iron program is a short 10-minute cycle (8 minutes of heat followed by a 2-minute Air Fluff period) designed to soften clothing fibers that have been left in the same position for an extended period. It relaxes the fibers, making them easier to iron and fold. It is not a drying program and should not be used for wet articles of clothing. For best results with Easy Iron, do not exceed maximum load capacities (e.g., 5.5 lb / 2.5 kg for Regular Cotton) and unload the dryer immediately after the program ends.
The manual provides detailed dismantling instructions for various components, emphasizing safety precautions such as unplugging the machine and being aware of sharp edges.
