Generic advice to service appliances annually is not useful, because a technician on an annual visit will not necessarily touch the thing that is actually shortening the machine’s life. On most appliances there is one component that nobody cleans, that is easy to reach, and that quietly decides whether the machine lasts six years or twelve.
This page names that part for each appliance in a typical Delhi home, and says how often to deal with it under local conditions — fine dust, very hard water, heavy cooking and an unstable supply.

In this guide
1. Fridge — the condenser coils at the back
This is the most neglected part in any Indian kitchen and the easiest win on this page.
- What it is. The black grille or coil pack at the back of the fridge, or on some models a hidden coil behind a lower panel. It is how the fridge throws heat away.
- What Delhi does to it. Fine dust settles into a felt-like mat across the coils and the fan. The fridge can no longer shed heat, so the compressor runs longer, hotter and louder, and its life shortens.
- What to do. Pull the fridge out twice a year and brush or vacuum the coils and the fan area. Ten minutes, no tools, switch it off at the socket first.
- The second thing. Check the door gasket by closing the door on a currency note. If it pulls out with no resistance, the seal is leaking and the fridge is running far more than it needs to.
- Leave a gap. A hand’s width behind, clear space above, and nothing stored on top.

Two things, and both are about what stays inside the machine after the wash.
- The drain pump filter. A small screw-out cap behind a flap at the bottom front of most front loaders. Coins, hairpins, lint and safety pins collect there and eventually strain the pump. Clear it every couple of months. Put a towel and a shallow tray down first.
- The detergent dose. Hard Delhi water stops detergent lathering, so people add more. The surplus never rinses out and leaves residue that stiffens seals, feeds smells and blocks the drain path. Measure the dose and use a detergent made for hard water instead of a bigger scoop of a cheap one.
- Leave the door and drawer open. Between washes, always. It is the single habit that prevents the musty smell — see washing machine smells.
- Space the loads. Households that run four loads back to back in the water supply window work the motor and bearings much harder than the same loads spread out. Put a gap between them where you can.
- Check it is standing level. A machine that rocks vibrates its own bearings apart over the years.
3. Chimney and microwave — grease and ventilation
Both of these fail from the same cause in an Indian kitchen: a build-up nobody can see.
- Chimney — the filters, monthly. Not annually, whatever the manual says. Soak baffle or mesh filters in very hot water with a strong degreaser for twenty minutes rather than scrubbing cold. On auto-clean models, empty the oil collector cup on the same schedule. Once grease gets past the filter onto the blower, it becomes a professional job. Our chimney care tips cover the routine, and this guide covers what to do when suction is already gone.
- Chimney — the outlet flap. Check once a year that the flap on the external wall actually opens when the chimney runs. They jam shut with grease and paint.
- Microwave — the vents and the waveguide cover. Keep the side and rear vents clear, never boxed into a tight cabinet cut-out. Wipe the cavity ceiling and the small mica waveguide cover; baked-on splatter there causes arcing. Steam a bowl of water for two minutes first and the grease wipes off easily.
- Microwave — never run it empty. With nothing to absorb the energy, the magnetron takes the load itself. It is one of the few things that damages a microwave in one go. See microwave not heating.
4. Water heater, dishwasher and the supply they all share
Hard water and unstable voltage are the two things that shorten the life of everything electrical in a Delhi home.
- Geyser — the heating element and the anode rod. Scale coats the element in hard water until it takes far longer to heat and eventually fails. The sacrificial anode rod protects the tank from corrosion and is a consumable that almost nobody replaces. A periodic descale and an anode check are the two jobs that extend a storage geyser most. Our geyser not heating guide covers the symptoms.
- Dishwasher — the filter and the salt. The mesh filter at the bottom of the tub traps food and must be rinsed regularly. In hard water, dishwasher salt is not optional; it is what keeps the internal softener working and stops scale and white film on the dishes. Running one without salt in Delhi water is why people conclude dishwashers do not work here.
- Everything — voltage. Control boards are the most common expensive failure in modern appliances and they dislike spikes and dips. Stabilisers on the large appliances, surge-protected boards for electronics, and switching things off during a power cut all help. See using appliances in a power cut.
- Everything — hard water. If your taps and shower heads scale up quickly, every water-fed appliance in the house is scaling up too. Our hard water home tips cover the options.
Watch out a burning smell, a hot plug or socket, or an MCB that trips when one appliance runs are all reasons to stop using it and get it checked, not to keep going.

How often should I clean the back of my fridge?
Twice a year is a sensible interval in Delhi, and more often if your home is on a dusty road or near construction. Fine dust mats onto the condenser coils and fan at the back, so the fridge cannot shed heat and the compressor runs longer and hotter than it should. Switch off at the socket, pull the fridge out, and brush or vacuum the coils and fan area. It takes about ten minutes and needs no tools.
What is the most neglected part of a washing machine?
The drain pump filter, which sits behind a small flap at the bottom front of most front loaders. Lint, hair, coins and safety pins collect there and eventually strain the pump and slow the drain. Clear it every couple of months with a towel and a shallow tray underneath, because water will come out. The second most neglected thing is the detergent dose, since hard water tempts people into using far more than the machine can rinse away.
Does hard water shorten appliance life in Delhi?
It shortens the life of the parts that touch hot water in particular. Scale coats geyser and washing machine heating elements until they work harder and eventually fail, and it leaves white film in dishwashers that are run without salt. If your taps and shower heads scale up quickly, everything water-fed in the house is scaling too. Descaling on a schedule and treating the supply are the two practical answers.
Do I really need a stabiliser for appliances in Delhi?
It depends on your supply, and there is an easy test: if your lights visibly dim and brighten through the evening, your voltage is swinging enough to matter. In those areas a stabiliser on the fridge and air conditioner, and surge-protected boards for electronics, are worth it, because control boards are the most common expensive failure in modern appliances. If your supply is steady and you rarely see flicker, it matters much less.
