Key Signs That It’s Time to Replace My Dishwasher
Not sure whether to repair or replace your machine? These are the most common signs that your dishwasher is past its prime — and likely costing you more in energy, water, and frustration.
My Dishwasher Is Over 10 Years Old
If your dishwasher is over a decade old, there’s a good chance it’s living on borrowed time.
- The average lifespan is around 9–12 years
- Older machines are less energy-efficient and noisier
- Replacement parts may be hard to find or too expensive
Even if it seems to be working, an older dishwasher might be wasting water, using more electricity, or not cleaning as effectively as newer models.

My Dishes Aren’t Coming Out Clean
One of the most obvious signs it’s time to replace your dishwasher is when it simply stops doing its job.
If you’re pulling out plates with stuck-on food or cloudy glasses, despite using rinse aids or cleaning the filter, it’s probably not you — it’s the machine.
Common issues include:
- Weak water spray or low pressure
- Incomplete detergent dissolving
- Ineffective heating elements
If you’ve already tried troubleshooting and you’re still rewashing dishes by hand, it’s time to let go.

My Dishwasher Is Getting Too Loud
Is your dishwasher starting to sound like a lawnmower? That’s not normal.
While some noise is expected, loud or strange sounds are a warning sign of internal issues like:
- A failing motor
- Broken pump or bearings
- Loose components
Newer dishwashers are designed for quiet operation — many run under 50 dBA, which is practically silent.

My Dishwasher Is Leaking or Leaves Water at the Bottom
A puddle under your dishwasher or standing water inside it isn’t just annoying — it’s a clear sign that something’s wrong.
Signs you shouldn’t ignore:
- Water pooling under or around the base
- A soggy floor after every cycle
- Standing water inside the tub after a full run
Leaks may be caused by a cracked hose, worn-out door seal, or failing internal parts. While small leaks might be fixable, recurring moisture issues can lead to mold, floor damage, or even electrical hazards.
👉 If you’re constantly mopping up after your dishwasher, it’s probably time to replace it.

I See Rust Inside the Dishwasher
Rust in your dishwasher isn’t just unsightly — it’s a red flag.
What it might mean:
- The protective coating on the racks is wearing off
- Metal components are corroding
- Water is reaching areas it shouldn’t
Rust flakes can break off and stick to your dishes or clog your filters, leading to even more issues down the road.
Even worse, rust inside the tub usually means the unit is beyond repair.
🛒 Modern stainless steel tubs are more durable and hygienic.

The Door Doesn’t Latch Properly
If your dishwasher door no longer closes snugly or pops open mid-cycle, you’re likely dealing with a mechanical issue — and possibly a safety hazard.
Common symptoms:
- The latch doesn’t engage or feels loose
- You have to press or hold the door shut to start a cycle
- Steam escapes during operation
Sometimes, the problem lies with the latch mechanism or control board. But if the repair is over $150 and your dishwasher is already aging, replacement is usually the smarter long-term move.

My Dishwasher Is No Longer Energy or Water Efficient
If your dishwasher is more than a few years old, it’s likely using far more electricity and water than necessary — even if it still works.
New Energy Star-rated dishwashers use less than 4 gallons per cycle and can cut your energy bills by up to $35/year compared to older models.
Efficiency issues to look for:
- Long cycle times with poor cleaning
- No eco mode or sensor-based washing
- Excessive water usage (over 6 gallons per cycle)
📉 Over time, an inefficient machine can cost you more than a new one.

Should I Repair or Replace My Dishwasher?
Wondering if it’s worth fixing your current machine? Here’s a quick rule of thumb:
If the repair costs more than 50% of the price of a new dishwasher, it’s time to replace it.
When a repair might make sense:
- The dishwasher is under 5 years old
- It’s a minor issue (e.g. door gasket, clogged filter)
- You’ve had no previous problems
When replacement is the better choice:
- It’s over 8 years old
- You’ve had multiple repairs
- Parts are no longer available or too expensive
