What causes mold growth in your dishwasher?
Over time, food particles get stuck in various seals, racks, and crevices inside the dishwasher. This food is a perfect nutrient source for mold to grow. Coupled with water, heat, and a dark environment, mold will grow quickly inside the dishwasher. It’s often tucked away around the door seals where you cannot see it growing, so it goes unnoticed until it becomes a bigger issue.
The mold growth could be any number of mold spores present in the air, so some growth may be hazardous to your health, while others are not. Mold Busters can visit your home and take samples of the mold to be tested to identify the type of mold growing in your dishwasher.
If your dishwasher is leaking, the mold can be growing outside your unit. Therefore, cleaning the dishwasher inside is only part of the solution. If you have a leak and you notice discoloration or odors in your cabinets or outside your dishwasher, you may have a leak causing mold growth around the dishwasher instead of inside it. If you think you have an exterior mold colony growing, contact a professional inspectors at Mold Busters right away to have a complete inspection done.
Signs of mold inside your dishwasher
There are many signs to indicate that you have a mold issue inside your dishwasher. Some are obvious, while others can be hidden and hard to locate. We will give you a few more common places to check to see if you have a mold issue inside your dishwasher.
Have you ever opened your dishwasher and got a musty or foul smell coming from inside? This is certainly a sign that you could have mold growing inside your dishwasher. It could be just a build-up of food leftover from the previous wash cycle, but it could also be mold growing somewhere in your machine.
Mold on dishes and dishwasher rack
If there is a large enough colony of mold growing inside your dishwasher, and you don’t run the machine every day, you could find that the mold will start growing on your dishes. This happens because there is a build-up of food on the dishes that will feed the mold spores and cause them to grow. The food is a great source of nutrients for the mold to thrive. This is also true for the dishwasher rack. The same rules apply since the dishes sit on the rack and food particles get lodged on the racks causing the mold to start to colonize on them.
Mold in drain hose
A drain hose is also a great place for mold to start growing. It’s a warm, damp, dark environment with lots of food sources holding up in various places. The mold will attach itself to the food particles throughout your drain hose and start growing. It may get washed away when the drain cycle is run; however, the water never gets through the entire hose; therefore, mold will seek these drier but damp areas to form.
Mold in vent
Similar actions take place in the vent of your dishwasher. The steam venting out while the dishes are drying causes an ideal place for the mold to congregate and grow. Warm and dark is the preferred environment for mold, and the vent provides this.
Mold behind dishwasher
If you have the telltale musty smell and looked inside your dishwasher to the best of your ability, you may have a leak outside your dishwasher. Removal of the machine may be necessary to find the growing colony. It could be growing on the wall, cabinets, on or under the floor covering. All of these are great places for mold to grow near your dishwasher. If you are experiencing any of the above, contact Mold Busters for a complete and intensive inspection to ensure your home and family are healthy and safe.
What does mold in your dishwasher look like?
Mold inside or behind your dishwasher can look like several different things. It could look like rust color spots on the interior of the tub.

Often, it will appear black or grey in color, but as with most mold growing, it can take on different appearances. The rule of thumb is, if it looks different or odd, contact Mold Busters for an inspection to know exactly what it is.
The same can be said for mold growing outside or behind your dishwasher. It can take the appearance of black, green, or dark brown spots, or it can be a full-blown colony growing behind the dishwasher for an extended period that you did not realize was there.
