Miele G4920SC Review - Performance and Verdict Review


Miele G4920SC – How well does it wash?

Following another

pre-dishwasher test breakfast of scrambled egg, Weetabix and red wine,

we loaded the Miele with a selection of dirty kitchen crockery, pots,

pans and utensils to best replicate a real-world load. In went our trio

of test items that include dried on Weetabix in a ceramic bowl, a greasy

wine glass and the Pyrex bowl used to cook the scrambled egg in a

microwave. The first test run the Miele’s Sensor wash programme and a

second ran the Eco mode, using a leading brand triple action dishwasher

tablet throughout.

We had to run the main sensor wash twice as we

didn’t believe our own results the first time. All three test items

were spotless – including the ‘impossible’ scrambled egg bowl – and

the Miele had used barely 12 litres of water and 1kWh of juice in just

over 2 hours. Run number two proved the Miele is also consistent as we

got almost exactly the same result.

The glass and breakfast bowl

were clean, dry and polished to perfect cupboard dry with no signs of

smears of streaks. Yet it was the scrambled egg test that had us truly

impressed. The Miele turned in a near perfectly clean bowl in a test we

had designed to not be possible for an automatic dishwasher to clean


Whether our resident farm chickens were laying eggs

with less sticky proteins this week we couldn’t tell, but the Miele’s

results speak for themselves. That is the cleanest egg test bowl of any

machine we have tested so far.

Perhaps predictably the ECO

programme was a less efficient at cleaning, although the egg test

results were still up there with some of the best models. The glass and

breakfast bowl were excellent and there was no drips or pools of water

left inside the machine at all.

However, the ECO mode took

nearly four hours to compete and used only fractionally less water and

energy then the sensor programme.

Miele G4920SC – How much will it cost to run?


G4920SC is an incredibly efficient machine in its standard sensor

programme and one of the most economical dishwashers we have tested to

date. It is probably only its slightly higher water use that stop it

being rated as an A machine overall. Stick to the sensor programme

and it certainly won’t be far off.

The sensor programme with the

dirty load used 1.09kWh of electricity and 12.2 litres of water while

the ECO mode registered 0.93 kWh hours and 9.9 litres of water. Key

difference in actual usability between the two is the time difference of

nearly an hour and half in the sensor mode’s favour. It takes a long

time to be ECO, apparently.

Based on running 250 dishwashing

cycles per year, half in sensor programme for heavily soiled loads and

half in ECO for lighter duties, the G4920SC would cost you less than £40

a year in electricity to run.

That is even more efficient than

Miele’s flagship A machine and the lowest electric consumption of any

dishwasher we have tested to date. For those on metered water the low

water use would only add around £5 for direct water usage.

Should I buy the Miele G4920SC?


It washes better than any machine we’ve tested and uses less energy

doing it, which is hugely impressive. It still has a premium asking

price, but if you’re a Miele fan then it’s a superb option if you can’t

stretch to the quieter, flagship model.

The one wrinkle is it’s

noisier than most machines in this class. Both the Samsung DW609970FS

and Whirlpool 6th Sense PowerDry ADP900IX are noticeably quieter and

clean almost as well, and the Miele is arguably the least attractive of

the three. Any of three will serve you well, though, so it comes down to

what you care about most when choosing. Head to our Best Dishwashers round-up for even more options.


An outstanding dishwasher that’s easy to use, efficient and cleans brilliantly.
