Bosch TWK7203 Stops mid-cycle and won’t resume: Meaning & Fix

If the Bosch TWK7203 stops heating and won’t resume, it’s commonly due to an overheat/dry-boil safety cutoff, limescale causing overheating, an unstable base contact, or temperature-related protection.

• 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).

• Dry-boil / low-water protection triggered (water below MIN or boiled dry).
• Overheating caused by heavy limescale.
• Intermittent contact between kettle and base (movement/angle).
• Ambient temperature extremes affecting sensors (less common).
• Internal control/heating fault (if it repeats after cleaning).

1. 1
   Check for heavy limescale; descale the kettle if needed.

   ExpectedLess overheating; stable heating.
2. 2
   Wipe the kettle’s base plate and the base contact pins with a dry cloth.

   ExpectedReduced intermittent cutouts.
3. 3
   Try a different outlet to rule out brief power dips.

   ExpectedStable power supply.
4. 4
   If it repeatedly stops even after descaling and contact cleaning, contact Bosch support/service.

   ExpectedService path initiated.

• 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.

• Descale on a schedule (hard water = more often).
• Avoid running near MIN; use a comfortable water volume.
• Place the base on a stable surface to avoid wobble.
