Do you have a question about the Bosch PSY6A6B20 and is the answer not in the manual?
This document describes the Bosch Built-in Gas Hob, model PSY6A6B20, a cooking appliance designed for domestic use.
The Bosch Built-in Gas Hob is designed for cooking purposes under supervision in a private household and domestic environment. It features multiple burners and an electric hotplate, allowing for versatile cooking options. The appliance can be used safely if correctly installed according to safety instructions, with the installer responsible for ensuring proper operation at the installation location. It is suitable for use up to an altitude of 2000m above sea level. The hob should not be used on boats or in vehicles, as a room heater, with an external timer or remote control, or outdoors.
The appliance incorporates an automatic ignition system for the gas burners. Users ignite a burner by pressing and turning the control knob anti-clockwise to the highest level, holding it for a few seconds until the flame ignites. A safety system (thermocouple) is integrated to interrupt the gas flow if a burner accidentally goes out, requiring the control knob to be held for a further four seconds after ignition to activate the system and enable gas flow. In the event of a power cut, burners can be lit manually using a lighter or flame. The electric hotplate can be switched on by turning its control knob clockwise to the desired position, with an operating indicator lighting up. A dual-circuit hotplate is also available, activated by turning its control knob clockwise to a specific setting.
The hob features various types of burners and an electric hotplate, each with specific power outputs:
The control knobs allow for incremental power level adjustments from 1 to 9 for gas burners, and specific positions for the electric hotplate, including "Off" (o), "Highest power setting and electric ignition" (9/09), "Lowest power setting" (1/1@), and "Ignition of the dual-circuit hotplate" (symbol). An operation and residual heat indicator is also present.
The appliance is controlled via control knobs, which are used to set power levels and activate functions. The burners consist of a burner cover, burner cup, thermocouple for flame monitoring, and an ignition plug. Pan supports are provided to hold cookware correctly over the burners; cookware should never be placed directly on the burner.
For optimal energy saving, users are advised to choose a burner roughly the same size as their pan and centre the cookware. Covering saucepans with suitable lids, lifting lids infrequently, and using glass lids are recommended. Using cookware suitable for the quantity of food and cooking with only a little water also contribute to energy efficiency. Turning down to a lower power level early on and utilizing the residual heat of electric hotplates for lengthy cooking times are further tips.
The manual provides recommended settings for various cooking tasks, including boiling, cooking, deep-frying, sautéing, braising, melting, defrosting, and fine dishes, with suggested power levels and cooking times. For instance, bringing water to the boil is recommended at power level 9, while starting cooking processes like pasta or soups is suggested at levels 7-9.
Specific accessories are available, such as an additional espresso maker grid (for use on the lowest power setting burner with cookware smaller than 12 cm diameter) and a simmer plate (for low heat cooking, preferably on economy or standard-output burners, placed with bumps facing up).
Regular cleaning and servicing are crucial for the appliance's long-term efficiency. After each use, the surface of the burner parts should be cleaned to prevent food remains from burning on. The burner parts and pan supports should be cleaned using a non-metallic brush and soapy water, then completely dried. It is explicitly stated that burner parts and pan supports should not be cleaned in a dishwasher, as this can cause damage.
When cleaning the appliance, the control knobs should not be removed to prevent humidity from damaging the interior. The appliance should be allowed to cool down before cleaning. Spilled liquids should be removed immediately to prevent food from sticking. Ignition plugs should be cleaned regularly with a small, non-metallic brush, taking care to avoid heavy knocks. Burner holes and grooves must be kept clean to ensure a correct flame.
The manual also includes a troubleshooting section to help users rectify minor faults themselves, covering issues like impaired electrical operation, automatic ignition not working, non-uniform burner flame, gas supply problems, gas smell, and burners switching off prematurely. For more complex issues or repairs, users are advised to contact Customer Service, emphasizing that repairs should only be carried out by trained specialist staff using genuine spare parts.
