How Can I Prevent This

Preventing any issues in a home is important for homeowners to understand. Every project has a process and a way to prevent any issues from arising again. Let’s take a look at how we can prevent mold growth on a washing machine rubber seal.

  • Detergent – use the detergent that meets the needs of your washer. If the washer is considered a high-efficiency washer, then you the detergent that is also considered high-efficiency. Limit the amount of detergent to the recommended amount.
  • The Door – keep the washing machine door open so that the washing machine can air out properly. Leaving the door open allows the moisture to escape and the area to dry properly.
  • Wet clothes – do not leave wet clothes in the washing machine. Immediately transfer the clothes to the dryer. This removes excess moisture from building up in the washing machine.
  • Wipe down – be sure to wipe the rubber gasket down after each wash. This leaves no guessing about the moisture drying and mold being kept away.
  • Dehumidifier – use a dehumidifier in the room that has the washing machine. This keeps the room less humid and removes the excess moisture from the room.

How Much Does It Cost

The cost to replace a rubber washing machine gasket can range from $50 to $300 depending on the make and model of the machine. However, simply removing the mold and keeping the rubber gasket clean should not cost you more than $25 for cleaning supplies.

Other Recommended Maintenance

Now that you know about mold in the washing machine, there are a few areas to maintain. One of those is the skylights in the home. If the skylight is not sealed, you will have water leaking in and this will contribute to a mold problem. Sealing a skylight is not difficult, it can be done by removing debris from the track but also using sealant and caulk.

While you are cleaning out the washer, take a look at the dryer. If you see water on the floor, the dryer is leaking water. This can be due to blocking of ventilation, vent duct issues, holes in the vent duct, or the vent flap is defective. Whatever it may be, fixing it will be cheaper than buying a new one so take care of it quickly.

Lastly, if you are changing out your refrigerator, you will need to know the amps a refrigerator uses. You will need to have a proper outlet circuit that is dedicated to the refrigerator. If you buy a refrigerator with an energy rating, this will help you keep your electric bill low. However, if it doesn’t have an energy rating, you can purchase an energy meter. This will calculate how much energy is used.
