Need help?Do you have a question about the Miele KM 240 and is the answer not in the manual?
This document provides operating instructions for Miele ceramic hobs, specifically models KM 240 to KM 247, which are used with the Hob-control Unit KSE 202-1. It covers essential information for installation, safe operation, and maintenance of the appliance.
The Miele ceramic hobs are designed for domestic use to cook food, including boiling, simmering, and frying. They feature multiple cooking zones with varying diameters and power levels, controlled by heat regulators. Some models (KM 243, KM 247) also include a dedicated warming zone. The hobs are classified as "Y" class for heat protection, allowing for installation with a wall at the rear and wall or tall units on one side, provided minimum distances are maintained.
The cooking zones are controlled by rotary knobs, which illuminate when a zone is switched on. The color of the display deepens from a light shade to red as the setting increases, indicating the heat level. An "Auto heat-up" feature is integrated into the cooking zone controls. When activated, the cooking zone quickly reaches a high initial temperature before automatically switching to a pre-selected continuation setting, reducing the need for manual adjustment. The duration of the "Auto heat-up" period varies depending on the chosen setting, with settings 1-7 (for boiling) having longer periods and settings 8-12 (for frying) having shorter periods. This feature can be deactivated if desired.
Certain models (KM 243, KM 247) feature extended cooking zones, which can be activated using their corresponding controls. An indicator light in the hob display field illuminates when the extension is switched on. The warming zone, available on some models, is controlled by sensor touch pads. It has its own indicator light and a residual heat indicator.
A safety feature known as the "hob lock" is available to prevent accidental activation of the cooking zones, particularly when the hob is used in conjunction with an oven or an oven with built-in hob controls. This lock does not apply to the warming zone.
To ensure optimal performance and safety, users are advised to place a saucepan containing water or food on the cooking area before switching on a zone. This prevents unnecessary energy consumption and potential damage to the hotplates. Pan bases should be clean and dry. For maximum energy efficiency, only pans with flat or very slightly concave bases should be used, as they rest evenly on the hob. Modern saucepans designed for electric cookers are particularly suitable. Cooking with a lid on the pan helps retain heat.
The operating instructions provide suggested hob settings for various cooking tasks, such as melting butter, keeping food warm, defrosting, boiling, frying, and browning meat. These settings are given as a guide, and actual cooking times may vary based on pan type, food quantity, and recipe.
The residual heat indicator for each cooking zone lights up when the zone is active and remains illuminated after the zone is switched off until the ceramic surface has cooled to a safe-to-touch temperature. Similarly, the warming zone also has a residual heat indicator.
Regular cleaning and care are crucial for maintaining the ceramic hob surface. For general cleaning, the same agents used for ordinary glass surfaces can be applied. However, abrasive scouring agents, pads, strong cleaners, oven sprays, or stain removers should be avoided as they can damage the surface.
Minor spills that have not dried can be wiped off with a damp cloth or sponge. If washing-up liquid is used, light blue staining may occur, which can be removed with a proprietary ceramic hob cleaning agent, though it might require several applications. For stubborn spillages, a shielded razor blade scraper is recommended, followed by wiping with a damp cloth or sponge.
Light marks with a metallic sheen, often caused by aluminum deposits from pans, can be removed once the hob has cooled down using a suitable proprietary cleaner. Lime deposits, resulting from boiling water or damp pan bases, can be cleaned with vinegar or a proprietary hob cleaner.
Crucially, if solid or liquid sugar, plastic, or aluminum foil gets onto a hot ceramic hob, the appliance should not be switched off. Instead, the residue should be immediately scraped off with a shielded razor blade scraper, taking care to avoid burns. Allowing these residues to cool before cleaning can lead to pitting or cracking of the ceramic surface.
Some cleaners contain silicone, which forms a protective film on the hob, making the surface smoother and preventing water and soiling from adhering. However, this effect is reduced by high-temperature cooking and requires reapplication.
Users are warned not to use the hob as a resting place for other items, as this could pose a fire hazard if the hob is accidentally switched on. Dropping objects like salt cellars can damage the ceramic hob. Pans with pronounced edges or ridges should be avoided, and enamelled pots or chip pans should not be pushed across the surface, as these can cause scratches.
In the event of breakages or cracks in the ceramic hob, the appliance must be immediately switched off and disconnected from the electricity supply, and the Miele Service Department should be contacted. The hob should not be used until the damaged ceramic plate has been replaced, as liquids could penetrate electrical components through cracks, posing a danger.
