Quick answer

For the Bosch WTWH7660GB, Anti-Crease is a programme setting, not a fault code. The exact Bosch instructions say the option can be set to Anti-Crease 60 minutes, Anti-Crease 120 minutes, or deactivated for the selected programme. They do not document a separate global master switch that permanently disables it for every programme. Before starting a load, select the Anti-Crease option until it is off and verify the display; if you want a repeatable preset, the manual says a Favourite programme can save customised programme settings and retain them after the dryer is switched off, but it does not explicitly promise that an off state applies to every programme. Do not use a hidden menu, service mode, wiring change, or modification. If the option cannot be changed as the exact manual describes, record the model, display, and selected programme and arrange Bosch service.

Before you begin

Safety first

  • Do not use a hidden menu, service mode, firmware change, wiring modification, or cabinet opening to disable Anti-Crease. Do not reach into a rotating or hot drum. If cancelling early, follow Bosch's heat-dissipation warning; stop immediately for smoke, burning odor, abnormal heat, or electrical damage.

Diagnostic checks

Use only checks that match the exact appliance or system and its official guide.

  1. Check 1

    Confirm the rating-plate E-Nr, including any suffix such as /05 or /07, and record which programme is selected. Photograph the display showing Anti-Crease 60 min, Anti-Crease 120 min, or the off state before pressing Start.

    Expected result: The label is WTWH7660GB with a suffix, only the base model is known, or the option appears in a different form on the display.

    Next step: Use the manual matching the complete E-Nr and keep the selected programme with the record. If the suffix cannot be confirmed, use only the visible setting control and ask Bosch support to match the document.

    Stop if: Do not open the cabinet or use a hidden/service menu to identify the model or disable the option.

    Why this matters

    Why: Bosch lists multiple E-Nr variants under WTWH7660GB and the manual says model differences can be relevant. A base model name alone cannot justify another variant's button sequence or a claim that a setting is global.

  2. Check 2

    On the selected programme, press the Anti-Crease control repeatedly until the display shows the off state, rather than 60 min or 120 min. Make the selection before starting the programme and verify the indicator visually; do not apply pressure with a sharp object to the touch display.

    Expected result: The display cycles through 60 min, 120 min, and off; it stays on one duration; or there is no Anti-Crease control/indicator for the selected programme.

    Next step: Leave the option off for this programme if that is your preference. If it cannot be changed, record the exact display and programme and arrange Bosch support; do not enter service mode or rewire the dryer.

    Stop if: Do not use a sharp object, force the touch panel, or open the control console.

    Why this matters

    Why: Bosch's manual explicitly supports activating 60 or 120 minutes or deactivating the option. A control that cycles normally is a user setting; a control that cannot change as documented is a support/service issue, not permission to modify the appliance.

  3. Check 3

    If the dryer has the Favourite programme control, create or overwrite a Favourite only after setting the desired programme and Anti-Crease state. Follow the manual's documented save action and then inspect the Favourite before starting a later load; do not assume this changes every programme.

    Expected result: The Favourite recalls the selected programme with Anti-Crease off, recalls a different state, or the model's display does not offer Favourite.

    Next step: Use the saved Favourite only when its displayed settings are verified. If it cannot retain or recall the intended state, select off manually for each programme and ask Bosch support whether the specific E-Nr has a documented limitation.

    Stop if: Do not invent a button combination, alter firmware, or access appliance settings beyond those documented in the manual.

    Why this matters

    Why: Bosch says Favourite saves customised programme settings and retains selected settings after the appliance is switched off. The manual does not explicitly state that Anti-Crease off becomes a global setting for all programmes, so a different programme may still show its own option.

  4. Check 4

    Observe the end of one normal programme without opening the door during active drying. Let the cooling phase finish, then remove the laundry promptly if desired. If a programme is cancelled early, follow Bosch's warning: remove the laundry immediately and spread it out to dissipate heat.

    Expected result: The drum moves intermittently after drying, the Anti-Crease indicator is off but the programme still cools, or the display shows a fault, abnormal heat, smoke, or an unresolved stop.

    Next step: Allow normal cooling and remove laundry after the programme ends. For smoke, burning odor, abnormal heat, or a fault, stop using the dryer and arrange qualified service; do not repeatedly cancel to test it.

    Stop if: Do not reach into a rotating drum, stop a hot programme without spreading the laundry, or operate after smoke or burning odor.

    Why this matters

    Why: Anti-Crease movement is distinct from the normal cooling phase. Bosch warns that cancelling before cooling completes can leave laundry hot; an off setting does not cancel required cooling or prove an energy fault.

  5. Check 5

    If the option appears to return, compare the next programme's display before Start with the prior Favourite or programme. Record whether only Anti-Crease changed, whether a different programme was selected, and whether the issue is a setting display or a dryer that continues tumbling despite an explicit off state.

    Expected result: The setting returns only on a different programme, returns after selecting a saved Favourite, remains visibly off but the drum still cools, or remains visibly on and cannot be disabled.

    Next step: Use the documented off control on the programme you intend to run. If the displayed state is off yet movement is only during cooling, treat that as normal; if the state remains on or the control is unresponsive, arrange Bosch support with photos and the full E-Nr.

    Stop if: Do not use a hidden menu, reset sequence, service mode, or physical modification to force the feature off.

    Why this matters

    Why: A different programme or preset can carry its own setting. Continued drum movement during CoolDown is not Anti-Crease proof. A visible on-state that cannot be changed as the manual describes is the only configuration symptom that needs model-specific support.

  6. Check 6

    Prepare a service handoff only if the exact documented control cannot change or the dryer shows a separate abnormal symptom. Include the complete E-Nr, programme, Anti-Crease display state, Favourite state if used, timing of drum movement, and any code, heat, odor, noise, or power symptom.

    Expected result: The option remains stuck on despite the exact manual's off selection, the dryer behaves abnormally outside the setting, or the only concern is that Anti-Crease is inconvenient.

    Next step: For a stuck control or separate abnormal symptom, contact Bosch or a qualified appliance technician. For ordinary Anti-Crease behavior, use the documented off selection or verified Favourite and no repair is indicated.

    Stop if: Do not order a control panel, board, or sensor from the setting complaint and do not open the dryer.

    Why this matters

    Why: A stuck user control or unrelated operating fault is different from a normal per-programme setting. Convenience alone does not establish a component defect or justify a modification.

Use your observations

Decision map

Find the observation that best matches what you see, then follow the next safe action.

  1. PATH 01Next step

    What you see

    The Anti-Crease control cycles between 60 min, 120 min, and off for the selected programme, and the displayed off state is accepted before Start.

    Do this next

    Run the programme normally with the verified off state, or save a Favourite with the desired settings if the model offers that control. Check the display again whenever a different programme is selected.

    Why this path and its safety boundary

    Why it matters: The documented per-programme setting is functioning. Bosch does not establish a separate global master switch in the opened manual.

  2. PATH 02Next step

    What you see

    Anti-Crease appears again only after selecting another programme or preset, while the option can still be switched off for that selection.

    Do this next

    Select off on the programme you intend to run and verify it before Start; optionally use a verified Favourite. Do not change hidden settings or firmware.

    Why this path and its safety boundary

    Why it matters: The behavior is consistent with a programme-specific setting or preset rather than a failed dryer. The manual's Favourite feature can retain customised settings, but it is not documented as a global override.

  3. PATH 03Next step

    What you see

    The display visibly remains on Anti-Crease and will not reach off when the exact manual's control is used, or the dryer continues the feature after an explicit off state.

    Do this next

    Keep the dryer safe and contact Bosch support or qualified appliance service with the full E-Nr, programme, display photos, and behavior. Do not use service mode or modify the appliance.

    Why this path and its safety boundary

    Why it matters: This is a model-specific control or configuration discrepancy that the opened documents do not resolve. It is not enough evidence to name a board, touch panel, or other part.

  4. PATH 04Next step

    What you see

    Smoke, burning odor, abnormal overheating, damaged power connection, repeated electrical trip, or a drum that does not stop occurs while changing or observing the setting.

    Do this next

    Stop the dryer, isolate power only from a safe dry location, and arrange qualified appliance/electrical service; use emergency help for active smoke or fire.

    Why this path and its safety boundary

    Why it matters: This is a heat, fire, electrical, or injury hazard and is separate from a normal Anti-Crease configuration question.

Helpful context

Understand the symptom

The WTWH7660GB is a Bosch Series 6 heat-pump tumble dryer. Bosch's product record describes an Anti-Crease cycle at the end of the programme, and the opened manual identifies the control as a programme setting with 60-minute, 120-minute, and off choices. This is a configuration question, not evidence of a motor, sensor, or control fault.

The manual explains that Anti-Crease moves the drum at intervals after drying to help prevent creasing. It tells you how to deactivate the option for the selected programme, but its separate appliance-settings list covers items such as child lock, quiet drying, display brightness, and notification volume—not a global Anti-Crease disable. Therefore a setting that returns on a later programme is not proof that the dryer is malfunctioning; it may simply be a per-programme selection or the selected preset.

If you cancel a drying programme early, Bosch warns that laundry may not have cooled sufficiently. Let the programme complete when safe, or remove and spread the laundry immediately if you must cancel. Do not change firmware, use a hidden menu, enter service mode, disconnect a feature, or open the cabinet to solve a normal setting behavior.

When checks do not resolve it

Need a professional?

Call Bosch support or qualified appliance service for a control that cannot reach the documented off state, a visibly off setting followed by unexplained Anti-Crease movement outside CoolDown, or any separate heat/electrical fault. No repair is indicated when the setting can be turned off per programme.

Safety scope: Do not use a hidden menu, service mode, firmware change, wiring modification, or cabinet opening to disable Anti-Crease. Do not reach into a rotating or hot drum. If cancelling early, follow Bosch's heat-dissipation warning; stop immediately for smoke, burning odor, abnormal heat, or electrical damage.

Have this ready

  • Provide the full E-Nr and suffix, selected programme, Anti-Crease display state before Start, Favourite settings if used, when drum movement occurs, and any fault code, heat, odor, noise, or power observation.

Common questions

FAQ

Can Anti-Crease be permanently disabled on the Bosch WTWH7660GB?

The exact manual documents Anti-Crease 60 minutes, 120 minutes, or off for the selected programme, but it does not document a separate global master switch. You can select off before each programme; a verified Favourite may retain customised settings, but that is not documented as an override for every programme.

Why does the drum still move after I turn Anti-Crease off?

Check whether the movement is only during the normal cooling phase. Bosch says the dryer can remain hot and use CoolDown after pausing or cancelling; that is distinct from the Anti-Crease option. Do not interrupt a hot cycle just to test the distinction.

Should I change a hidden setting or enter service mode to stop Anti-Crease?

No. Bosch provides a visible off selection for the programme setting. If the exact control cannot reach off, keep the dryer unmodified and contact Bosch support with the full E-Nr and display behavior rather than using a hidden menu or rewiring the appliance.
