5 common mistakes that reduce the lifespan of your appliances

Silent wear begins with everyday use

The useful life of an appliance rarely ends because of one dramatic failure. Instead, it usually degrades slowly through everyday habits that seem harmless: overloaded compartments, unsuitable cleaning, forgotten objects, extreme temperatures in the plumbing, and postponed maintenance. That gradual wear increases vibration, heat, residue and energy consumption, and exposes sensitive parts —motors, seals, heating elements, pumps and electronics— to premature failure. If you have a problem with your appliance, you can use our free error code finder. From there you can find out and solve all errors easily and effectively.

1. Overloading the refrigerator and freezer

Why it damages

Filling the fridge or freezer to the brim blocks air circulation and creates uneven temperatures. The compressor and fans must run longer to compensate, frost accumulates in specific areas, and internal components are exposed to constant thermal stress. Over time this continuous effort shortens the life of compressors, fans and insulation and reduces food preservation quality.

How to prevent it

• Leave free space for air to move between containers and avoid packing flexible bags against the walls.
• Organize by zones and avoid placing hot food directly inside; let it cool first.
• Minimize the time the door stays open by planning what you will take out.

2. Cleaning with unsuitable products and neglecting small dirt

Why it damages

Using harsh detergents, abrasive pads or common soaps on delicate surfaces can scratch finishes, weaken seals and leave chemical residues. At the same time, letting filters, spray arms, condenser grilles and door gaskets accumulate dirt, grease or dust forces motors and heating elements to work harder and reduces heat dissipation.

How to prevent it

• Use cleaners recommended for each material and prefer soft cloths and lukewarm water when possible.
• Clean washing machine filters, dishwasher spray arms and the back condenser of refrigerators regularly to maintain thermal exchange and drainage.
• Wipe oven interiors after heavy use and remove food residues from dishwashers before running a cycle.

3. Leaving coins, buttons and small objects in clothing

Why it damages

Forgotten keys, coins, clips or screws turn washers and dryers into impact chambers. These objects can scratch drums, get stuck in filters or pumps, damage gaskets, and cause intermittent faults that are hard to trace. In dryers, combined heat and friction increase the risk of mechanical wear, noise and internal marks.

How to prevent it

• Check pockets and garments before washing; use a small laundry bag for delicate items.
• Keep metal objects away from laundry areas and empty lint filters after each dryer cycle.

4. Using very hot water in the sink and poor plumbing practices

Why it damages

Running extremely hot water for long periods can push grease and debris into drain pipes where they cool and stick, creating persistent deposits that narrow passages and impair flow. This clogs filters and spray arms in dishwashers, stresses seals and plastic connections, and increases the risk of leaks. Water temperature swings and high inlet temperatures can also shorten the life of components designed for a specific range.

How to prevent it

• Avoid flushing large amounts of hot grease down the sink; collect cooking oils and dispose of them properly.
• Use sink strainers and run a moderate-temperature rinse rather than continuous very hot water.
• Keep drainage systems clear with periodic maintenance to protect dishwashers and in-sink plumbing.

5. Putting off maintenance — and ignoring electrical and ventilation issues

Why it damages

Delaying routine maintenance is the most expensive form of wear. Clogged filters, blocked vents, dusty condensers, and postponed inspections force appliances to operate beyond optimal levels. Additionally, unstable or overloaded electrical installations —poor outlets, chained extension cords, or low-quality power strips— cause voltage spikes and intermittent shutdowns that damage control boards, motors and electronic components.

How to prevent it

• Establish simple periodic checks: clean or replace filters, inspect door gaskets, clear vents and dust condenser coils.
• Avoid chaining extension cords or using underspecified power strips for high-consumption appliances; use dedicated circuits where recommended.
• Respond to small noises, leaks or changes in cycle time promptly—early repairs cost less than major replacements.

Practical checklist to extend appliance life

• Allow airflow: don’t overcrowd fridges or freezers.
• Use the right cleaners: soft cloths and material-specific products.
• Check pockets: remove coins and metal objects before washing.
• Manage kitchen grease: avoid pouring hot oil down the drain.
• Maintain regularly: filters, gaskets, vents and condenser coils.
• Protect the electrical supply: avoid overloaded outlets and use proper wiring for heavy appliances.

Small daily habits compound over time. Consistent, appropriate use and basic preventive maintenance are the cheapest and most effective ways to keep appliances working longer, use less energy and avoid repeated repairs.
