Home appliances are essential components of our daily lives, facilitating household tasks and enhancing our comfort. To ensure these valuable allies perform optimally for many years, proper maintenance is crucial. In this article, we will provide practical tips for the correct maintenance of major appliances such as boilers, refrigerators, washing machines, dryers, and ovens. We will explain the importance of regular cleaning, filter replacement, and other preventive operations to ensure their longevity and efficiency.


As we already saw in this article, boilers play a crucial role in providing home comfort. To maintain their efficiency and safety, it is essential to subject the boiler to annual maintenance by a specialized technician. During maintenance, the professional will check the system’s pressure, clean heat exchangers and burners, and inspect for any gas leaks. Additionally, periodically bleeding the radiators will eliminate any trapped air that could reduce the system’s efficiency.


Refrigerators are among the most frequently used appliances in the home, but subject to accumulation of bacteria and mold. To keep them in optimal working condition, regular cleaning of both the interior and exterior is crucial, using special products or hot water and vinegar. Unplugging the appliance from the power source and removing the grilles and rear panels will allow you to eliminate accumulated dust from the condenser coils. Ensure that the door gaskets are tightly sealed to prevent cold air leaks. Also, avoid overloading the refrigerator, as excessive food items can obstruct the circulation of cold air.

In case you have to turn it off for long periods, check that it is completely empty and leave the door ajar, to avoid bad smells.

Washing machines

Washing machines undergo intense usage, but with proper maintenance, they can last for years without issues. After each wash, leave the washing machine door slightly open to allow the interior to dry and prevent mold formation. Periodically clean the drum and drain pipes to prevent the buildup of dirt and unpleasant odors. Additionally, pay attention to the manufacturer’s instructions for proper detergent dosing, as excess foam can damage the appliance over time.

The most recent washing machine models have the option of carrying out a special cleaning cycle: consult the instruction manual.


Similarly, dryers require regular cleaning as a fundamental part of maintenance. After each drying cycle, remove and clean the dryer lint filter from any lint residues. Check and clean the air exhaust ducts periodically to prevent blockages that could compromise the appliance’s proper functioning and increase the risk of fires. Also, avoid overloading the dryer, as this can reduce the efficiency of the drying process.

To optimize and reduce the drying process, you can buy special wool balls, which help absorb water and help iron the creases.


Dishwashers are one of the great allies in the kitchen, simplifying the task of washing pots, pans and utensils. To keep them efficient and ensure optimal cleaning results, proper maintenance is essential. After each washing cycle, it is advisable to clean the filters to remove food residues and debris that may obstruct the water flow. Regularly check and clean the spray arm to ensure even water distribution during the wash.  Also check that there are no grease deposits along the seals. Additionally, use specific cleaning products regularly to remove limescale and prevent the formation of deposits on the internal components.


The oven is another crucial appliance in the kitchen that requires proper maintenance to ensure optimal performance and safety. Regularly cleaning the oven is essential to remove food residues, grease, and crumbs that accumulate during cooking. It is advisable to use safe cleaning products to avoid damage to the interior and exterior surfaces. Remove and clean the racks and heating elements periodically to ensure optimal airflow and even cooking.

To prevent the buildup of grease and splatters inside the oven, using trays or parchment paper during cooking is helpful. Additionally, regularly check the oven door gasket and ensure it is in good condition to maintain an airtight seal and proper heat distribution. If you notice issues like irregular temperatures or prolonged cooking times, it is advisable to seek the assistance of a specialized technician to check for any malfunctions or the need for extraordinary maintenance.

Spending the time to properly maintain major appliances can mean the difference between a long, efficient life and troublesome operation. Regularly cleaning your appliances, replacing filters, and scheduling preventative maintenance will help keep your appliances in top condition and save on costly repairs or replacements. Remember that although maintenance may take some effort, the benefits will be visible over time with appliances working to the best of their ability, ensuring comfort and safety in your home.
