Bosch WQG244C1TR Serie 6 heat pump dryer emitted smoke after service cleaning (Turkey)
Turkish owner complaint (Şikayetvar) for a Bosch Serie 6 heat pump dryer (WQG244C1TR). After a paid cleaning by a Bosch-directed service, the machine emitted smoke at night, filling the home with a burnt smell; the owner demanded replacement. Single-owner report, not an official recall.
What to check. If smoke or burning smell appears from the dryer, unplug it immediately and do not resume use until an independent inspection; consider replacement if the unit has been serviced.

Safety risk
Turkish owner complaint (Şikayetvar) for a Bosch WQG244C1TR/05 purchased 23.10.2024.

Bosch WQG244C1TR/05 heat pump dryer keeps heating after programme end; owner reports fire risk (Turkey)
Safety risk
Finding came from the query 'Bosch WQG244C1TR kurutma makinesi yangın'. A verified owner complaint (Şikayetvar, 29 May 2025) about a Bosch WQG244C1TR/05 heat pump dryer bought 23 Oct 2024 in Turkey: the machine kept running the heat pump with intense heat after the programme ended, creating serious overheating and a fire risk. A technician said there was no problem; the fault recurred 11 times over 6 months. This is a TR-market, non-WDT67 Bosch heat pump dryer, matching the subject.
What to check. An owner reports a fire risk on this model: the dryer continued heating after the programme ended. If a Bosch heat pump dryer runs hot after the cycle finishes, treat it as a safety concern, stop using it, and escalate beyond a single service visit (the owner reports the fault was dismissed and recurred 11 times).
Bosch WQG24500BY heat pump dryer withdrawn from Serbian market — UMAC compressor wiring electric-shock risk
Official CEFTA market-surveillance record (economy: Serbia) for Bosch model WQG24500BY, barcode 4242005303526, made in Poland. The compressor's electrical connection was not made to specification during production, creating an electric-shock risk if installed in a household whose electrical installation does not meet safety guidelines. This is the only official recall/withdrawal record I found for a Bosch heat pump dryer in the European region; note the market is Serbia, not EU or Turkey.
What to check. If you own a WQG24500BY, check the serial number against the Serbian ministry list and contact BSH/Bosch service for inspection; the risk depends on the household's electrical installation.
German owner complaint (ReclaBox) for a Bosch WTY 88931 heat pump dryer, 31 months old. The house circuit breaker tripped during operation and the machine would not restart; a technician could not locate the fault. Single-owner report of an electrical defect.
What to check. If a heat pump dryer trips the circuit breaker or RCD during operation, stop using it and have the insulation/electrical system checked before further use.
