A dishwasher fills up with water

Anyone who opens their dishwasher door in mid-wash will see a surprisingly small amount of water – less than a bowl-full in the base of the machine.

This is because a dishwasher actually cleans and recycles small amounts of water to be ultra-efficient. It's been calculated that 10 litres of water has the equivalent cleaning effect of 4,000 litres, passing through the dishwashing machine

Deadly fungi and bacteria build up inside damp dishwashing machines

Deadly fungi and bacteria build up inside damp dishwashing machines

We face bacteria everyday and everywhere in our lives. At home, it is mainly the kitchen where most of the bacteria are found. This is due to food remnants, humidity and insufficient kitchen hygiene. Indeed, wet and dirty hand wash utilities, wiping towels and the kitchen drain itself provide perfect living conditions for fungi and bacteria if these items are not cleaned regularly.

The high temperatures in a dishwashing machine plus the bleach in the detergent guarantee that bacteria don’t survive a dishwashing cycle. However, food remnants can build up on the door gasket and seals of a dishwasher. Because these parts don’t get in contact with water and detergent, they need to be cleaned regularly by hand. Clean the door gasket with a damp cloth to remove food particles and other debris. Also clean the door seal, located inside the dishwasher at the bottom of the door.

Dishwashers are not for small families or couples

Many people think they won’t have enough dishes to fill a dishwasher and so may not be using it efficiently. However, dishwashers come in a range of different sized models, not only 60 cm wide appliances.

For example, modern slimline dishwashers are only as wide as a standard cupboard at 45cms, while compact dishwashers can fit on worktops. Slimline models can be loaded with 8 to 9 place settings, compact dishwashers with 4 to 6 place settings. And both dishwasher types work as efficiently as the standard sized model. Before purchasing a dishwasher, it is useful to review the amount of dishes available.

Many standard sized dishwasher models feature the half-load function for when just a few items need to be washed. That means only upper or lower basket contents are cleaned during a cycle.

Items washed by hand come out cleaner than in a dishwasher

For getting a good cleaning result when washing dishes by hand, you need to bring in a lot of mechanical force as this is the main cleaning factor. Temperature and the hand wash liquid itself are less effective and the detergent needs to be a mild formulation.
This is different for automatic dishwashing where temperatures can rise up to 70°C and the detergent includes different ingredients which are specially formulated to remove various food residues, like oil, protein or bleachable stains. A dishwasher works more effectively on food stains, as proven in different studies by Bonn University. Results show that washing in a dishwasher leads to better cleaning results than washing by hand.

Any unreliable cleaning results could be due to poor loading, or use of low quality detergents. See our Tips section!

A dishwasher doesn't clean Kadai, pots, pans and cookware properly.

A dishwasher doesn't clean Kadai, pots, pans and cookware properly.

Heavily soiled items like Kadai, pots, pans and cookware should be washed in an intensive cycle with higher temperatures. Together with the dishwashing detergent recommended by your manufacturer, even the toughest stains like grease, oil and baked-on food will be removed.

Finish Detergent contains powerful stain-soaking enzymes and due to its fast solubility (< 5 minutes) it releases the enzymes early in the cleaning cycle when the lower temperature (< 50°C) creates the right conditions to break down baked on stains. This means you don’t need to pre-wash those tough to clean dishes like Butter Chicken or Dal Makhni

A dishwasher has high electricity consumption.

A dishwasher has high electricity consumption.

Washing dishes by hand uses more water than using a dishwasher. The electricity in a dishwasher is used to heat up the water which is pumped and recycled around the machine. Since in a dishwasher less water is used, the electricity needed to heat up the water is also less.

Compared to washing dishes by hand, dishwashers use much less water. A modern dishwasher needs as little as 6.5L of water, while washing up the same amount of dishes by hand uses up to 49l (Source Intertek). Dishwashers heat up the water in a very efficient way by using a continuous-flow heater which results in less heat loss than heating water in a electric geyser and transporting it to the sink. In addition, the appliance is insulated to avoid heat losses from the interior space.

Your best glasses get damaged in the dishwasher

Glassware is generally suitable for the dishwasher: However, depending on the type of glass and the conditions in the machine, in a few instances the glass may become cloudy. A fundamental distinction can be made between two different clouding effect on glass:


1) Lime deposits: These are caused by inadequate water softening, and can easily be removed again by rubbing with citric acid or vinegar. To prevent lime deposits from the beginning, please ensure that your water softener unit is set correctly, and that the dishwashing machine is regularly refilled with salt and is dosed with an adequate quantity of rinse aid.

2) Glass corrosion: Glass corrosion is a form of damage to the glass which cannot be rectified, caused by the washing-away of the surface of the glass. Glass damage such as this can also be seen on standard window glass which turns “opaque” over time. Poor glass quality, very severely softened water in the dishwasher, as well as high temperatures and long programme cycles are critical factors in the occurrence of glass corrosion. The following tips should help you to prevent corrosion to your glasses:

  • When buying glasses, pay attention to whether they are guaranteed dishwasher-proof
  • Ensure that your water softener unit is set correctly.
  • Only clean your glasses at low wash temperatures, e.g. in glass / gentle / delicate / quick programmes
  • Once the wash programme is completed (after drying!), open the dishwasher door briefly and allow the water steam to be drawn off. This is not necessary if your machine is equipped with a drier fan. Only remove glasses once the machine has cooled down.
  • Ensure that the rinse agent setting is adequate.
  • Use dishwasher detergents such as Finish which have been tested for their care of the items to be washed in the dishwashing machine

This is true on Eco- or Energy Saving Cycles, recommended for every day loads with normal soil levels. In these programmes, the water is heated up and circulated in a much longer time compared to normal or even intensive cycles, which saves a lot of energy.
And if you have lightly soiled dishes such as glasses, cups and saucers, use a short / gentle / delicate / glass programme which only takes around 30 minutes to run.

Dishwashers can be a useful and valuable labour saving investment for their owners, who soon realise their many unexpected benefits. However, many non-owners fear they won’t be able to fill it or find space for it in their kitchens.

That’s why dishwashers come in a range of different sized models, not only 60 cm appliances. For example, modern slimline dishwashers are only as wide as a standard cupboard at 45cms, while compact dishwashers can fit on worktops. Slimline models can be loaded with 8 to 9 place settings, compact dishwashers with 4 to 6 place settings. And both dishwasher types work as efficiently as the standard sized model

Before purchasing a dishwasher, it is therefore quite useful to recap the amount of dishes that need to be cleaned in the household. And if you still want to buy a standard sized dishwasher, there are models featuring the half load function for when there are just a few items to wash.

Your dishwasher comes with a full range of different programmes that suit a variety of occasions ranging from daily loads to party dishes and family feasts such as Diwali, New year when it really comes into its own:



  • For daily loads Eco, Automatic and Regular programmes are suited to clean large and mixed loads with normal soiling.
  • For parties where glasses are needed very urgently in a short period, a quick or short cycle is the ideal choice to clean lightly soiled items perfectly. Use Finish detergents which are perfectly suited also for short cycles.
  • Family occasions like Diwali/Dusshera bring a lot of joy but also a lot of dirty dishes and cookware after a delicious meal. Your dishwasher is perfectly able to deal with this using the Power Scrub / Intensive Programme. Together with Finish detergent, you will even be able to get rid of oily, baked-on or dried-on food remains on Kadais and pans.
