Quick answer

On a Bosch tumble dryer, E06 means a fault in the heating circuit. Bosch says only an experienced engineer can fix it: switch the dryer off, unplug it and book a repair without opening it.

Safety first

Stop and check this first

  • If E06 appears with a burning smell or smoke, unplug the dryer and do not use it again until a technician has checked it.

Safe checks you can perform

  • Power off and note the code
  • Fluff filter before the visit
  • Heating circuit measurement

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Measuring each circuit component
  • Do not attempt this professional task: Heating test after the repair

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Measuring each circuit component

    What they doWith the power off, the technician uses a multimeter on the heater, the thermal protection and the wiring of the heating circuit.

    They must show youeach measured value against the Bosch specification.

    In writingthe component out of specification, any replaced part with its reference and the reason.

  2. Heating test after the repair

    What they doThe technician runs a drying programme and checks the air heats up and E06 does not return.

    They must show youthe programme running and heating with no code.

    In writingthe programme tested, the result and the date.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Power off and note the code

    No special tools

    Who:
    you, no tools.
    How:
    switch the dryer off, unplug it and note the code and the model number (E-Nr) on the door rating plate.
    Result that matters:
    having the details the service will ask for.
    If the code came with a burning smell or smoke:
    do not plug it back in and tell the technician when booking.
    If there was no other symptom:
    get the details ready and book the visit.
    Evidence to keep:
    a photo of the display with E06 and of the rating plate.

  2. Fluff filter before the visit

    No special tools

    Who:
    you, dryer unplugged.
    How:
    take out and clean the door fluff filter, as Bosch advises after each cycle.
    Result that matters:
    leaving the filter clean so the technician starts from a clear air path.
    If it was very dirty:
    leave it clean and mention it to the technician when booking.
    If it was clean:
    that factor is ruled out; do not keep running programmes to test.
    Evidence to keep:
    photos of the filter before and after.

  3. Heating circuit measurement

    Tools required

    Who:
    a Bosch service technician.
    How:
    with the dryer disconnected, they measure the heating circuit components and wiring.
    Result that matters:
    which component reads outside the manufacturer specification.
    If one component is out of specification:
    it confirms the part to replace.
    If all measure correctly:
    the fault points to the control and it must be checked.
    Evidence to keep:
    measured values against specification, in writing.

    The heating runs at mains voltage. Opening the dryer or measuring is for the technician only.

What it means

Bosch defines E06 as a fault with the heating circuit and says only an experienced engineer can eliminate it. That circuit includes the heater or system that warms the air, its wiring, its thermal protection and the electronics that control it. The code does not say which of these has failed: it shows the control saw something wrong while heating. So E06 on its own does not prove the heater needs replacing.

Warnings and stop conditions

  • Higheditorial warning

    If E06 appears with a burning smell or smoke, unplug the dryer and do not use it again until a technician has checked it.

Symptoms and causes

Probable causes · in order

  • Heating element or its connectionPossible

    Only told apart by measuring with the dryer open and powered off; nothing outside confirms it.

    Evidence: Dryer Error Code E06 | Bosch

  • Thermal protection in the circuitPossible

    An open protection device cuts heating even with a good heater; the technician tells them apart by measuring each part separately.

    Evidence: Dryer Error Code E06 | Bosch

  • Electronics controlling the heatingPossible

    If the circuit parts measure correctly, the fault may be in the control; the technician concludes this after ruling out the rest.

Does E06 still appear after these checks?

Answer a few questions to narrow down the likely cause and the safest next action. Guidance only - it never replaces a professional.
