Cleaning and maintenance
Before each operation, disconnect the appliance.
Cleaning the cooker
Drops of sauce, fruit juice etc., should be removed as soon as possible with a soft cloth soaked in warm detergent water. Do not use steel wool or knives to take off layers of crust. Remove stubborn marks with a well wetted soap impregnated pad, but care must be taken not to scratch the enamel. Wash the enamelled grids with water and detergent; these can also be washed a dishwasher. Take off the burner covers and the grids and wash them carefully with warm water and detergent. Dry them well before putting them back in position. Moreover, make sure that these are properly re-placed. The burner can be rubbed with steel wool or a slightly abrasive cloth. Clean the oven door and crystal cover, in models equipped with these items, only with warm water, and avoid the use of rough cloths or abrasive substances; in cookers with an automatic ignition the sparkling bulb should be cleaned periodically and accurately to avoid difficulties in lighting; furthermore check that the burner holes are not obstructed.
Light metallic stains (aluminium residues) can be removed from the cooking zone with a ceramic hob cleaning agent. Sugar solutions, food stuffs with a high sugar content must be removed immediately with a scraper. If this type of soilage is not removed immediately it can cause irreparable damage to the ceramic surface. When the surface has cooled wipe over with a damp cloth. Before using any detergent or cleaning agent on the ceramic top, ensure they are recommended by the manufacturer for use on ceramic hobs. Do not apply any cleaning agents to hot cooking zones. Ensure any residues are wiped off before the cooking zones are used again.
Oven lamp replacement (Fig. 10)
Disconnect the appliance. Unscrew the lamp and substitute it with another fitting for a higher temperature (300Â°C) with the folowing characteristics: Tension: 230 V (50Hz) Power: 15W Connection: E14
Cleaning the oven door
For a more complete cleaning of the oven door, it is advisable to disassemble it in the following way (Fig. 11): open the door fully, turn the two caps situated on the arm of the hinge to 180Â°, partially close the door to an angle of 30Â°, lift the door and extract from the front. Re-mount the door by reversing the operation described above.
Cleaning the oven
Clean carefully the oven cavity after use when it is still warm. In fact, at this moment it is easy to take off deposits of fat or other substances such as fruit juice, sugar particles or fat. You can use warm detergent water or one of the appropriate spray oven cleaners. Do not direct the spray at the mat steel parts as this could damage them and always follow the manufacturer's instructions. Clean the oven acces-sories (grate, gridplate etc.) with warm water and detergent. Remove possible incrustations with a slightly abrasive powder. Never line any part of the oven with aluminium foil. It would result in an accumulation of heat which might damage the cooking results and also damage the enamel.
Cleaning the hob
Before cleaning, make sure the hob is cool. Never use aggressive or abrasive agents, such as oven sprays, stain or rust removers, scouring powders, or sponges with an abrasive effect. Special cleaning agents and ceramic hob scrapers are available from department stores. Slight, non-burnt soilage can be wiped off with a damp cloth. Burnt soilage has to be removed with a scraper. Afterwards wipe off the ceramic hob with a damp cloth. Fig. 11
