Steam generator iron lifespan: how long does it last?

Short answer

Steam generator iron: 5 to 10 years on average, so around 7 years in normal household use. Regular maintenance routinely pushes past the top of that range.

A steam generator, like a steam iron, lasts 5 to 10 years. One factor separates the two extremes: limescale. In a hard-water area with no descaling, a generator gives up after four or five years; rinsed every quarter, it doubles its life.

Limescale does not kill the machine suddenly: it gradually cuts the steam output, stains laundry with yellow marks, then blocks the boiler. The signs show up long before the failure, which leaves plenty of time to act.

Signs it is reaching the end

Steam output weakens, or no steam comes out at all
Yellow or brown marks appear on the laundry
Flakes of limescale are spat out by the soleplate
The soleplate drags on fabric instead of gliding
The boiler takes much longer to be ready

The maintenance that extends its life

Empty the water tank after use to avoid deposits and smells
How often: after every session
Clean the soleplate with a suitable product, machine cold
How often: every month
Rinse the scale collector or the boiler as the manual describes (full descaling)
How often: every 3 months
Replace the anti-scale cartridge if your model has one, or as soon as the indicator says so
How often: every 3 to 6 months

Repair or replace?

A scaled-up generator is not a dead generator: before any quote, run a full descaling as the manual describes, which solves most steam problems. If the boiler is pierced or the pump has failed, repair often exceeds half the price of a new entry-level machine. On a premium generator, however, parts are available and repair still makes sense.

Frequently asked questions

How often should a steam generator be descaled?

Every three months is a good baseline, more often if your water is hard or you iron a lot. Some machines block steam production on their own when descaling is overdue.

Should I use demineralised water?

Follow the manual first: many manufacturers advise against pure demineralised water, which can cause spitting, and recommend mixing it with tap water. What to avoid in every case is rainwater, water softened by a salt-based softener, and scented water.
