The IFS (Institut für Schadenverhütung) is an independent German damage-prevention institute that examined multiple WDT67 heat pump dryers that caught fire while in operation. The fires were caused by an internal technical defect, with damage concentrated on the right side of the unit. Affected units are from build years 2020–2022. The IFS advises having the dryer checked by a qualified technician if drying performance drops and the manufacturer's manual remedies do not restore it.
What to check. Owners of a Siemens/Bosch WDT67 (build years 2020–2022) should not run the dryer unattended, and should have it inspected by a qualified technician if drying performance declines. This is a documented fire risk, not a general reliability issue.
WDT67 heat pump dryers (2020–2022) caught fire from internal technical defects — IFS investigation
Safety risk
The IFS (Institut für Schadenverhütung), a German damage-investigation institute, examined multiple WDT67 heat pump dryers that caught fire. Two detailed cases are described where units caught fire while in operation; both showed damage concentrated on the right side. The report states affected units are from build years 2020–2022 — matching the subject's date range. The IFS advises having the dryer checked by a professional if drying performance drops and manufacturer-recommended measures don't restore it.
What to check. Owners of WDT67 dryers from 2020–2022 should be alert to reduced drying performance as a potential warning sign. Have the unit inspected by a qualified technician if performance degrades. Do not leave the dryer running unattended. This is an investigation report and warning, not a formal recall — no official BSH/Siemens recall notice was found.
WDT67 drum motor fails to start — owner repair forum (WT47W584/07)
An owner reports the WDT67 (model WT47W584/07) stops working without an error message — the program appears to start, relays click, interior light comes on, but the drum motor does not turn. This is a repair-forum report of a common failure mode, not a safety defect.
What to check. If the dryer shows no error but the drum doesn't turn, the motor drive may be at fault. This requires professional diagnosis and likely motor replacement. Cost is moderate but the failure makes the dryer unusable.
An owner reports rumbling noises during drying. Replacing the suspected bearing didn't fix it; the drum support holders were found worn and the drum wobbles. This indicates drum bearing/support wear as a known failure on the WDT67.
What to check. Rumbling noises from the WDT67 may indicate worn drum bearings or support holders. Bearing replacement alone may not suffice — the drum support holders may also need replacement. This is a reliability issue, not a safety defect.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
