What Causes Water Leakage in Your Microwave

Microwaves are designed to heat food and not water. However, moisture can build up inside the microwave for various reasons, such as spills, condensation from cooking, overheating, or steam generated from cooking certain types of food.

This moisture can accumulate over time and cause the microwave to leak water.

Here are ten reasons that can cause a microwave to leak water:

1. Overheating


When a microwave overheats, it can cause water to evaporate, creating condensation that collects on the walls and ceiling of the oven. Overheating can occur due to a malfunctioning thermostat or incorrect microwave use.

2. Damaged Door Seal

Damaged Door Seal

The door seal is a crucial microwave component that prevents moisture and heat from escaping. If it becomes damaged, it will cause the spilled or condensed water to leak out of the oven during cooking.

3. Faulty Gasket

Faulty Gasket

The gasket is a seal between the floor and the microwave body. If it becomes worn or damaged, it will make the water leak out of the oven during or after the cooking session.

It is necessary to get it repaired or replaced. For example, some microwave ovens do not function with a faulty gasket.

4. Cracked Interior

Cracked Interior

A crack in the interior of the microwave can allow water to seep into the unit during cooking. This is more likely to occur in older microwaves or those subjected to physical damage.

During a prolonged cooking session, the steam from the heated microwave components can seep into the plate and leak when the door is opened.

5. Poor Ventilation

Poor Ventilation

Proper ventilation is essential to prevent condensation from building up inside the microwave. The vents are typically placed on top or the side of the microwave.

If the vents are blocked, or the fan is not working correctly, moisture can accumulate, causing water to leak from the microwave.

6. Improper Use of Containers

Improper Use Of Containers

Some containers are unsuitable for microwave use and can cause water to leak during cooking.

Glass containers can crack, and plastic containers can melt, causing the water to seep. These leaks can be cleaned easily and do not require mechanical repairs.

7. Splatters and Spills

Splatters And Spills

Sometimes, the food being cooked in the microwave gets overheated and spills out of the dish/container.

When the food splatters or spills in the microwave, it can create moisture that can collect on the walls and ceiling of the oven, causing water to leak out.

8. High Humidity

High Humidity

This is a rare phenomenon but is possible in high-humidity regions. High humidity levels in the environment can cause moisture to collect inside the microwave during cooking, resulting in water leakage.

9. Clogged Drain Hole

Clogged Drain Hole

Some microwave models come with a drain hole and a drip pan. They drain any water that spills into the drip pan, which you can later remove.

When the drain hole in the microwave becomes clogged with food particles, it causes the water to collect inside the microwave and spill when the door is opened.

10. Malfunctioning Control Board

Malfunctioning Control Board

This only happens if your microwave is a newer and advanced model.

The control board regulates the microwave’s temperature and can malfunction, causing the oven to overheat and create condensation that can collect on the walls and ceiling of the oven.

2. Clean Up the Water

Clean Up The Water

Using a dry cloth or paper towel, clean up any water leaking from the microwave. It is essential to do this carefully to avoid getting any water on the appliance’s electrical components.

If the water touches any active power source or a live wire, it can cause fatal damage to you or the appliance. It can also start an electric fire. Therefore, clean the leaked water before you move on to the next steps.

3. Inspect the Microwave

Inspect The Microwave

Once the water has been cleaned up, inspect the microwave thoroughly for any signs of damage or defects that could be causing the leakage.

Numerous reasons may cause the microwave to spill; you need to examine all of them and pinpoint the cause.

Check the door seal, hinges, loose parts, and any other microwave parts that may be causing the problem.

4. Check the Door Seal

Check The Door Seal

The door seal is a rubber gasket that surrounds the microwave door. Over time, this seal can become worn or damaged, causing the water to leak out.

A faulty door seal will also prevent your microwave’s door from closing properly, inviting dust and dirt inside the microwave. Small critters can also get inside your microwave and crawl further in, causing damage to the electrical components.

Check the seal for any cracks or tears, and replace it if necessary.

5. Check the Hinges

Check The Hinges

Hinges are the most important component of any machine. They hold the machine together, ensuring its parts are in place and working efficiently. Unfortunately, the hinges are another common cause of water leakage in microwaves.

If the hinges are loose or damaged, they can cause the microwave door to not close correctly, allowing water to leak out. Check the hinges for any signs of damage and replace them if needed.

6. Check the Microwave’s Venting System

Check The Microwave’s Venting System

The venting system in a microwave is responsible for removing steam and moisture from the microwave during cooking. If the vent is blocked or not working correctly, it can cause water to build up inside the microwave and leak out.

In case of heavy condensation inside the microwave, other microwave components can get damaged by water. Check the vent for any signs of blockage and clean it if necessary.

If it is blocked, remove the obstruction yourself or call a professional technician for assistance.
