- Unplug the kettle base from the wall socket for 60 seconds.ExpectedElectronics fully reset.
- Wipe the touch control area and base surface with a dry microfiber cloth.ExpectedControls are dry and responsive.
- Place the kettle back on the base so it sits flat and stable.ExpectedContacts align properly.
- Select a temperature (try 100°C) and press Start.ExpectedTemperature selection responds and heating begins.
On the Bosch TWK7203, the temperature selection can appear “locked” when the touch panel doesn’t register input, when the kettle isn’t seated correctly on the base, or when a mode like KeepWarm is active and the kettle is maintaining a set temperature.
- The kettle doesn’t behave as expected when you press Start or change temperature.
- The problem repeats until you change something (power, water level, seating, cleaning).
- Moisture/condensation on the touch controls prevents reliable input.
- Kettle is not seated flat on the base (contacts not aligned).
- KeepWarm or a prior temperature mode is still active, making it feel ‘stuck’ at a setpoint.
- Touch panel glitch/state confusion after a short power interruption.
- Limescale build-up causing inconsistent temperature behavior (less common).
- Let the kettle cool and dry completely if you just boiled water (steam can condense on the controls).ExpectedTouch input becomes stable.
- Try a different wall outlet to rule out intermittent power.ExpectedStable power supply.
- If KeepWarm was used, cancel it (if your variant has a KeepWarm toggle) and reselect a temperature.ExpectedTemperature selection changes again.
- Descale the kettle if you have heavy limescale; then retry.ExpectedImproved heating/temperature control stability.
| Checkpoint | What you do | If it passes | If it fails |
|---|---|---|---|
| Power & seating | Try a known-good outlet and reseat kettle on base | Kettle powers normally | Try cleaning contacts / support |
| Water level | Fill above MIN and close lid | Heats as expected | Dry-boil/overheat protections may be triggering |
| Scale & cleanliness | Descale and clean contacts | Stable performance | Possible internal fault → support |
- Trying to use the kettle when it isn’t seated flat on the base.
- Ignoring minimum water level or using it right after transporting in extreme temperatures.
- Do not immerse the base or power connector in water.
- Do not open the kettle or base (electric shock risk).
- Do not use abrasive cleaners on the contact pins.
- Unplug the base before cleaning and let the kettle cool before handling.
- Hot water and steam can cause burns—open the lid carefully.
Contact Bosch support if the issue persists after the steps above, or if you notice burning smell, visible damage, or intermittent power to the base.
- The kettle repeatedly fails to heat even with correct water level and a known-good outlet.
- The base or plug gets unusually hot, sparks, or smells burnt.
- You see cracked plastic, loose contacts, or water ingress near the connector.
- Keep the touch control area dry (wipe condensation after boiling).
- Always place the kettle flat on the base (don’t leave it angled).
- Descale regularly if you live in a hard-water area.
Does TWK7203 have multiple temperature settings?
Yes—this model line is marketed with multiple selectable temperature levels and a keep-warm function (feature availability can vary by region).
Why do the touch buttons stop responding?
Most commonly due to moisture/condensation or the kettle not seated flat on the base. Power-cycling and drying usually fixes it.
If it still won’t change temperature, what next?
Try a different outlet, then descale. If the panel stays unresponsive, contact Bosch support.
