Understanding every induction hob symbol is the fastest way to cook more precisely, safely, and efficiently. Modern induction hobs, like those from Hoover, use intuitive icons to control heat, activate zones, and manage safety features. This guide breaks down the most common symbols and how to use them confidently.
Power Symbol (On/Off)
The power symbol turns the induction hob on or off, activating the control panel and cooking zones.
This symbol typically looks like a circle with a vertical line. Once pressed, the hob becomes responsive to all other settings.
Remember to always ensure the hob is completely switched off after cooking: induction surfaces cool quickly, but residual heat can still be present.
Cooking Zone Indicators
Cooking zone indicators show which part of the hob you are controlling and where to place cookware. Each symbol corresponds to a specific zone, helping you apply heat precisely and avoid using the wrong area during cooking.
These are usually represented by outlined squares or circles that match the layout of your hob.
- Tap the zone before adjusting heat.
- Some hobs allow flexible zones for larger cookware.
- Active zones are often highlighted or illuminated.
Advanced models in our induction hob collection include flexible cooking areas for griddles and large pans.
Heat Level Controls (+ / – or Slider)
Heat level symbols adjust the power output, typically from level 1 (low) to 9 (high).
These controls may appear as:
- Plus (+) and minus (–) buttons
- A touch slider bar
- Numeric displays
Common use cases:
- Low heat (1–3): melting chocolate or simmering sauces.
- Medium heat (4–6): general cooking.
- High heat (7–9): boiling water or searing.
Induction reacts instantly, so increase heat gradually to avoid overcooking.
Boost Function (Power Boost)
The boost symbol provides maximum power instantly to speed up cooking tasks like boiling water. It temporarily increases heat beyond standard levels and then automatically returns to normal operation.
This is often labelled as "P" or shown with a flame-like icon.
- Boils water up to 50% faster
- Temporarily increases power above standard maximum
- Automatically returns to normal levels after a short time
A common mistake is using boost for too long can cause food to burn: switch back to standard heat once the desired temperature is reached.
Timer Symbol
The timer symbol allows you to set a cooking duration for each zone. Usually shown as a clock icon, it helps automate cooking and prevent overcooking.
How to use the timer:
- Select a cooking zone
- Tap the timer symbol
- Set the time using + / – controls
- The hob will switch off automatically when time ends
Expert tip: use timers for foods like pasta or rice to maintain consistent results.
Residual Heat Indicator (H)
The residual heat indicator shows when a cooking zone remains hot after use. Displayed as "H", it warns you not to touch the surface, helping prevent burns even after the hob has been switched off.
Even though induction hobs heat cookware directly, the glass surface retains warmth from the pan.
- "H" = hot surface.
- "h" (lowercase) = moderate heat.
Safety tip: always avoid touching the zone until the symbol disappears.
Child Lock Symbol
The child lock symbol, usually shown as a padlock icon, disables the control panel to prevent accidental activation or setting changes. It is especially useful during cleaning or in households with children, improving overall kitchen safety.
When to use it:
- When cleaning the hob.
- In households with children.
- To avoid accidental setting changes during cooking.
To activate, press and hold the lock symbol for a few seconds.
Pause / Stop & Go Function
The pause symbol temporarily reduces all cooking zones to low heat and restores them later.
- Often displayed as two vertical lines (like a pause button).
- Useful if you need to step away.
- Prevents food from burning.
- Restores previous settings with one touch.
This function is ideal when answering the door or handling multiple tasks in the kitchen.
Pan Detection Symbol
Pan detection symbols indicate whether suitable cookware is placed on the hob.
Induction hobs only work with compatible pans (magnetic bases).
If the symbol flashes:
- The pan is not induction-compatible.
- The pan is too small for the zone.
- The pan is not centred properly.
Use flat-bottomed, ferromagnetic cookware for best performance.
Flexible Zone / Bridge Symbol
The bridge symbol connects two cooking zones into one larger surface.
This is ideal for:
- Griddle pans
- Roasting trays
- Large pots
The icon often looks like two linked rectangles or a bracket.
Benefit: even heat distribution across larger cookware.

Common Mistakes When Using Induction Hob Symbols
Avoid these frequent errors to improve performance and safety:
- Ignoring residual heat indicators: the surface may still burn skin.
- Using incompatible cookware: not all pans work on induction.
- Overusing boost mode: can lead to uneven cooking.
- Not locking controls when cleaning: accidental activation is common.
- Using abrasive cleaners: be sure to always use a proper cleaning solution like a degreaser for induction and ceramic hobs to maintain performance and protect the hob surface.

Frequently Asked Questions about induction hob symbols
How do I unlock the padlock symbol on my Hoover induction hob?
If the padlock symbol is illuminated, the Child Lock is active and the hob will not respond to your touches. To unlock it, simply press and hold your finger on the padlock symbol for about 3 to 5 seconds. You will usually hear a beep, and the light will turn off, indicating the hob is ready to use.
Why is a symbol flashing and my pan isn't getting hot?
If a symbol (usually a "U" shape with a line under it) is flashing on the display, it means the pan detection system has engaged. The hob either cannot detect a pan, the pan is not placed in the centre of the zone, or the cookware is not induction-compatible. Try placing a magnet on the bottom of your pan; if it doesn't stick strongly, you cannot use it on an induction hob.
Does an induction hob symbol light up if water boils over?
Many modern Hoover induction hobs feature an automatic safety shut-off or overflow detection. If water boils over and spills onto the touch control panel, the hob will usually emit a warning beep, display an error symbol (often an "E" or a specific code), and automatically switch off to prevent damage and burns. Simply wipe the panel dry to resume cooking.
What is the difference between the uppercase "H" and lowercase "h" symbols?
Both symbols are residual heat indicators warning you that the glass is still warm from the pan. An uppercase "H" indicates that the cooking zone is still very hot and could cause a burn if touched. A lowercase "h" means the zone has cooled down significantly but is still warm to the touch. Once the "h" disappears, the surface is completely safe.
Does the Pause (Stop & Go) symbol turn off the induction hob completely?
No, the Pause or Stop & Go symbol does not turn off the hob completely; it simply drops the power of all currently active cooking zones to a minimal "keep warm" level. This feature is designed to immediately stop water from boiling over or food from burning if you get interrupted and need to step away from the kitchen. When you are ready to resume cooking, pressing the symbol again will instantly restore all your original heat settings without you having to reprogram them.
