How Long Do Kitchen Appliances Last? Lifespans, Maintenance & When to Replace
In this guide
Lifespan overview: all major kitchen appliances
The chart below gives typical lifespan ranges for every major kitchen appliance. These figures reflect well-maintained, average-use households in the UK. Heavier use, infrequent cleaning, or ignoring early faults can shorten any of these ranges significantly.
Appliance-by-appliance breakdown
Each appliance ages differently depending on what stresses it most: thermal cycling, moisture, motor wear, or constant compressor load. Here is what drives lifespan in each category, and the warning signs that a replacement conversation is approaching.
Fridge freezer
10–15 yearsWhat limits lifespan
- Compressor wear from running too warm or too cold
- Dirty condenser coils forcing the motor to overwork
- Degraded door seals letting warm air in continuously
- Positioning next to a heat source (oven, direct sunlight)
Signs it’s declining
- Food spoiling faster than expected
- Frost building up unusually quickly
- Constant or loud running motor
- Warm patches inside the fridge compartment
- Noticeably higher electricity bills
Oven
13–15 yearsWhat limits lifespan
- Grease and food residue damaging heating elements
- Over-reliance on self-clean cycles (high heat stresses the build)
- Door seal degradation letting heat escape
- Fan motor wear in fan-assisted models
Signs it’s declining
- Uneven cooking results or hot spots
- Temperature running noticeably high or low
- Heating element glowing inconsistently
- Door not closing flush against the seal
Hob
13–15 yearsWhat limits lifespan
- Spills left to burn onto ceramic or glass surfaces
- Using abrasive cleaners that scratch and weaken the surface
- Incompatible cookware on induction hobs (scratching the glass)
- Burner blockages on gas hobs from food debris
Signs it’s declining
- One or more zones no longer reaching temperature
- Cracks in the glass surface (replace promptly for safety)
- Gas burners igniting inconsistently or not at all
- Induction zones failing to detect compatible cookware
Dishwasher
9–12 yearsWhat limits lifespan
- Filter blockages from food debris
- Limescale buildup in hard water areas
- Overloading, which stresses the spray arms and pump
- Using incorrect detergent (hand-wash liquid causes suds and damages seals)
Signs it’s declining
- Dishes coming out consistently dirty or streaky
- Persistent bad smell even after cleaning cycles
- Water pooling at the bottom after a cycle
- Spray arms cracked or no longer rotating freely
Cooker hood
10–12 yearsWhat limits lifespan
- Grease filters left unclean, forcing the motor to work harder
- Carbon filters not replaced in recirculating models (every 3–6 months)
- Motor bearing wear from extended use at high speeds
Signs it’s declining
- Noticeably reduced extraction power on all settings
- Persistent grease or cooking smells after use
- Unusual grinding or rattling noise from the motor
- Lights failing and not fixable by bulb replacement
Washing machine
10–12 yearsWhat limits lifespan
- Consistent overloading wearing out the drum bearings faster
- Detergent drawer blockages leading to mould and seal damage
- Running every cycle at 60°C rather than 40°C adds thermal stress
- Failing to clean the filter regularly
Signs it’s declining
- Drum making a rumbling noise during the spin cycle (bearing wear)
- Violent movement or walking across the floor
- Water not draining at the end of a cycle
- Door seal cracked or leaking
Microwave
7–10 yearsWhat limits lifespan
- Running empty, which damages the magnetron
- Metallic objects causing arcing and internal damage
- Door seal wear reducing efficiency and safety
Signs it’s declining
- Food heating unevenly or taking longer than usual
- Burning smell or unusual noise during use
- Door not closing or latching cleanly
- Touchpad unresponsive or inconsistent
Repair or replace: how to decide
An appliance breaking down does not automatically mean it needs replacing. The right call depends on its age relative to expected lifespan, the nature and cost of the repair, and whether the underlying appliance has been reliable up to that point.
The 50% rule
If a repair quote exceeds 50% of the cost of a comparable new appliance, replacement is almost always the more cost-effective choice — especially if the existing appliance is also past 50% of its expected lifespan. Both conditions together make a strong case for replacing rather than repairing.
When does repair make sense vs. replacement?
Lean towards repair
- The appliance is under half its expected lifespan
- The repair cost is below 50% of a new equivalent
- It is a first or second fault — not a pattern of breakdowns
- The appliance is still under manufacturer warranty
- Spare parts are readily available for the model
- The fault is minor — a seal, a filter, a door latch
Lean towards replace
- The appliance is beyond or near its expected lifespan
- Repair cost exceeds 50% of the replacement price
- The same fault (or different faults) have recurred repeatedly
- Spare parts are no longer available or face long lead times
- Efficiency has dropped noticeably, raising running costs
- A safety issue is present (cracked hob glass, gas smell, electrical fault)
There is one additional consideration that the 50% rule does not capture: energy efficiency. An appliance approaching the end of its lifespan is likely significantly less efficient than a modern equivalent — particularly for fridge freezers and dishwashers, where efficiency gains over the past decade have been substantial. Replacing an ageing fridge freezer with a well-rated model can reduce its annual running cost by £30–£50, which compounds meaningfully over the 15-year lifespan of the new unit. The guide to energy ratings explains how to read the current A–G label and what the efficiency difference actually costs per year.
- A cracked hob glass surface should be treated as urgent — continued use risks electrical or thermal injury. Do not use the hob until it has been assessed or replaced.
- Any gas smell from a hob or oven is a safety issue requiring immediate action. Stop using the appliance, ventilate the room, and contact a Gas Safe registered engineer.
- A microwave with a damaged or poorly sealing door should not be used. The door seal is a safety component, not just a convenience feature.
Maintenance habits that genuinely extend lifespan
Most premature appliance failures trace back to a small number of neglected maintenance tasks. The timeline below covers the minimum schedule for keeping each major appliance running well.
-
After every use
Wipe down hob surfaces while still warm (before spills bake on). Clear the dishwasher filter of large food debris. Remove the washing machine detergent drawer and rinse it if there is visible buildup.
-
Monthly
Check the cooker hood grease filter — if it looks visibly saturated, clean it. Run the dishwasher on a maintenance cycle with a dishwasher cleaner to prevent limescale and odour buildup. Run the washing machine on a 60°C empty cycle with a drum cleaner.
-
Every 3–6 months
Replace the carbon filter in any recirculating cooker hood — this is the most commonly neglected task, and a saturated carbon filter means the hood is doing almost nothing to remove cooking odours. Check fridge door seals by closing a piece of paper in the door: if it slides out easily, the seal needs replacing. Vacuum the condenser coils at the back or underneath the fridge freezer to prevent the motor from overworking.
-
Annually
Descale the dishwasher thoroughly if you live in a hard water area. Clean the oven interior — baked-on grease eventually affects heating element performance and is a fire risk. Check the washing machine filter (usually at the front base) and clear any debris.
-
At purchase / installation
Read the manual for ventilation clearances on the fridge freezer. Position the fridge away from the oven, dishwasher, or any other heat source. Ensure the washing machine feet are levelled correctly — an unlevel machine vibrates more violently during spin cycles, accelerating drum bearing wear.
For cooker hoods specifically, filter maintenance is the single biggest factor in longevity. A regularly cleaned grease filter keeps the motor running at the resistance it was designed for. A saturated filter makes the motor work significantly harder — which is both wasteful on energy and one of the most common causes of premature motor failure. The cooker hood guides section covers maintenance in more detail for different hood types.
Frequently asked questions
Key takeaways
- Hobs and ovens last the longest — typically 13 to 15 years — because they have fewer moving parts and are primarily mechanical.
- Fridge freezers last 10 to 15 years but must run continuously, making maintenance (condenser coils, door seals, correct temperature) the most critical factor.
- Dishwashers and microwaves have the shortest typical lifespans at 9–12 and 7–10 years respectively, and are the most affected by day-to-day usage habits.
- Use the 50% rule: if a repair costs more than half the price of a new equivalent, and the appliance is over halfway through its expected life, replacement is almost always the better choice.
- Filter and seal maintenance is the most neglected factor in appliance longevity — particularly for cooker hoods, dishwashers, and fridge freezers.
- An ageing, inefficient appliance may be costing more to run than people realise. Checking the running costs of kitchen appliances can help inform the repair-or-replace decision.
