Why does my cooling unit cause an unpleasant smell?
There is a drain channel at the rear of the cooling unit (see picture). This can become clogged with deposits, so you should check and clean it regularly.
The drip tray located on the back of the refrigerator (see picture) can also be responsible for unpleasant odours. It is always possible that spilled liquid accidentally gets into the drip tray via the drainage channel. Before cleaning the drip tray, first disconnect the machine from the mains. Then clean the inside of the appliance, all the rubber seals and also the drain hose that transports the drain water into the tray.
