A Practical Guide to Household Appliance Maintenance

Most appliance faults don't happen suddenly. They develop over time — through gradual wear, accumulated debris, or small neglected problems that slowly worsen. The good news is that a fair number of common breakdowns can be delayed or prevented entirely through straightforward, regular maintenance. This guide covers the basics for the three appliances we're called out to most: washing machines, fridges, and ovens.

Why maintenance matters

Household appliances are significant purchases — and replacing them is expensive. A washing machine that might otherwise last twelve years might fail at eight if it's never been properly maintained. A fridge that runs more efficiently stays cooler at lower electricity use. An oven that's kept reasonably clean is less likely to develop heating element problems caused by grease build-up.

None of this requires special equipment or technical knowledge. It's mostly about cleaning at the right intervals, using appliances within their intended limits, and paying attention when something changes — a new noise, a change in performance, a small leak.

Washing machine maintenance

Clean the door seal regularly

The rubber seal around the door of a front-loading washing machine collects moisture, soap residue, and debris. Left unchecked, it becomes a breeding ground for mould — which causes the musty smell many people associate with washing machines. Wipe the inside of the seal with a damp cloth after every few washes, pulling back the fold to clean underneath. If there's visible mould, a diluted white vinegar solution applied with an old toothbrush usually takes care of it.

Check and clean the pump filter

Most washing machines have a small access panel, usually at the bottom front, concealing a pump filter. This catches debris — coins, hair grips, fluff — before it reaches the pump. A blocked filter is one of the most common reasons a machine fails to drain properly, or starts making grinding noises. Check it every few months: place a towel under it before opening, drain the small amount of water that will come out, and rinse the filter under a tap.

Run a maintenance wash

Running the machine empty at 60°C or 90°C once a month helps clear residue from the drum, hoses, and internal components. You can add a dedicated washing machine cleaner, or simply a cup of white vinegar in the detergent drawer. Avoid using excessive amounts of detergent during regular washes — excess suds leave deposits that can affect the drum bearings over time.

Don't overload

Consistently overloading a washing machine puts significant strain on the drum bearings and motor. Most modern machines have a rated capacity of 7kg to 10kg. As a rough guide, there should be a hand's width of space between the top of the laundry and the drum's interior ceiling when loaded.

Fridge and freezer maintenance

Keep the condenser coils clear

The condenser coils at the back or underneath your fridge release heat as part of the refrigeration cycle. When they're coated in dust, they can't dissipate heat efficiently — which means the compressor works harder and runs longer. Once or twice a year, pull the fridge away from the wall and vacuum or brush the coils. It takes ten minutes and can meaningfully extend the compressor's life.

Check the door seal

A fridge door seal that doesn't close fully allows warm air to enter constantly, forcing the compressor to work harder and raising your electricity bill. Test it by closing the door on a piece of paper: if you can pull the paper out easily, the seal may need replacing. Seals can also be cleaned with warm soapy water if they've become stiff — a pliable seal makes a better contact with the fridge body.

Don't set the temperature too low

Fridges are most efficient — and food is best preserved — at temperatures between 1°C and 4°C. Freezers should be set to around -18°C. Running either significantly colder than necessary wastes energy and puts unnecessary strain on the compressor. If your fridge has a built-in thermometer, check it periodically to ensure the setting is being maintained.

Defrost the freezer when ice builds up

If your freezer doesn't have an automatic defrost function, frost will accumulate over time and reduce the available storage space and efficiency. Defrost it once the ice layer is about a centimetre thick — leaving it much longer makes the job harder and reduces performance. Turn the freezer off, remove contents to a cool bag, and allow the ice to melt naturally (place towels around the base).

Oven and cooker maintenance

Clean the oven regularly

This is arguably the most neglected maintenance task in most kitchens. Grease and food debris that accumulates on oven walls and the floor of the cavity can catch fire during cooking, and also affects temperature distribution. More significantly, heavy grease build-up on or near the heating elements can cause them to fail prematurely. You don't need to clean the oven after every use, but a thorough clean every few months — or more often if you cook frequently — is worthwhile.

For most ovens, removing the shelves and soaking them separately while cleaning the interior makes the job more manageable. Purpose-made oven cleaners work well, but follow the instructions carefully and ensure the oven is ventilated when using chemical cleaners.

Keep the hob burners clear

On gas hobs, blocked burner holes prevent gas from flowing evenly, resulting in irregular or low flames. Burner caps can be removed and soaked in warm soapy water — use a toothpick or a pin to clear the individual holes if debris has hardened. On ceramic hobs, spills should be wiped up promptly before they bake on and become harder to remove.

Check the door seal

The seal around the oven door retains heat during cooking. When it deteriorates — becoming brittle, torn, or no longer flush with the door frame — heat escapes, cooking times increase, and energy is wasted. Replacement oven door seals are widely available for most models and are a DIY-friendly replacement for most people comfortable with basic tasks.

General habits worth developing

A few broader habits apply across all household appliances:

• Read the manufacturer's manual — especially the maintenance and cleaning sections. They often include model-specific advice that makes a real difference.
• Don't ignore small changes in behaviour. A new noise, a slight vibration that wasn't there before, or a small change in performance often signals an early-stage fault that's cheaper to address sooner than later.
• Keep appliances clean and dust-free around vents and fans. Restricted airflow causes overheating in dishwashers, fridges, and tumble dryers.
• Avoid exposing appliances to extremes they're not designed for — overfilling a washing machine, storing items on top of a fridge that block ventilation, or using oven settings above the rated temperature.

When to call an engineer

Good maintenance reduces faults — but it doesn't eliminate them. Components wear out. Seals age. Electronic boards fail. When something goes wrong that you can't easily address through cleaning or a simple user-serviceable fix, the right call is to contact a professional rather than attempt an internal repair without the appropriate training or tools.
