• A burning-like smell, which is unique to any electric appliance, may be generated at the initial use of the dishwasher, but this smell will decrease when you use the dishwasher 10 - 20 times.

• If you will be absent for an extended period of time, there may be an odor from inside of the appliance.




• Check the filter

• Check for food in the bottom of the unit or in the filter.

• Clean the filter and the interior according to maintenance section of the owner's manual.

• Clean the filters with a soft brush under running water.

Additional Information A customer made the observation that no information was provided with respect to the gray port inside the dishwasher midway up on the left wall. That part is known as the “Air Guide”.



The Air Guide serves two (2) main purposes. It is the point of entry where water gets into the dishwasher and it measures the supplied water quantity. As well, the dishwasher drains itself through the air guide where a syphon flap gate prevents the dishwasher from syphoning itself empty. Unlikely source of nauseating smells.
