Why does your washing machine smell like a sewer or rotten egg?

There are two reasons for the rotten egg smell likely; the result of dirt, moulds, mildew, lint, and soap buildup. Thus, it causes bacteria to build up in your washing machine. Regular cleaning of the washer is necessary because grime can build up and cause damage to the rubber mat or between drums. If you don’t clean your washing machine regularly, it will mess inside with dirt that builds up under the floor mats in-between each drum.

As this thick layer fills with filth over time, more gunk may accumulate. It makes its way into clothing by clinging onto fabrics during every wash cycle leading to diminished quality for years before rust begins underneath from all of this moisture collecting around metal parts like bearings and wiring.

Sometimes, small objects, such as socks or rags, can get stuck behind the gasket in front-loading washers. The stuck object remains wet, and fungus, mould, mildew, and bacteria are inevitable.

A natural gas leak is another less usual option. Given the odourless nature of natural gas, utilities add sulfur to it to give it a scent of the red egg so that it may be noticed when leaking. If you suspect a natural gas leak, immediately call your gas companies, who have the necessary tools.
