How to choose the best dishwasher
If you’re looking for a new dishwasher, this guide will give you the information and insights to find one that will fit your home and lifestyle perfectly. As a global leader in home appliances, we know a thing or two about what makes a great dishwasher that will save you time and effort. This guide introduces all the latest dishwasher features and technologies, and shares hints on how to get the most from your appliance.
When you wash dishes by hand, you’re restricted by both the water temperature and the power of washing up liquid as both must come into contact with your hands without discomfort. By contrast dishwashers use water heated up to 70°C which is much more effective at removing bacteria, and dishwasher detergents contain powerful ingredients to target stains and food residue. Some dishwashers feature specific hygiene programmes, like Bosch’s HygienePlus, which rinses dishes with water heated to 70°C - perfect for households with small children or allergy sufferers.
Through the use of advanced technology, energy efficient dishwashers use less water and electricity, and you will still get sparkling results. Look out for machines with EU energy ratings of A++ and A+++, which are not only better for the environment but will save you money on your bills. And innovations like Bosch’s LoadSensor detect when you’re washing a smaller load to make sure only the necessary amount of water and electricity is used.
Many dishwashers offer a range of programmes to cater for different loads, dirtier dishes and for when you’re in a hurry. Typical programmes include delicate 40°C for shining glasses, economy mode to save water and energy, and intensive 70°C to shift heavy grease deposits. You should also look out for flexible programmes like Bosch’s IntensiveZone, which gives a deeper clean to items in the bottom drawer when needed.
There are quick wash programmes available on most dishwashers, but many of these can leave dishes damp. Advanced programmes like Bosch VarioSpeed Plus can wash and dry a full load of dishes perfectly clean, by reducing rinse time by up to 66%. Simply select the VarioSpeed Plus option when you need dishes quickly.
Bosch recommends large and tall items go in the bottom rack with their dirty surfaces facing the centre and any openings facing downwards. The top rack should be reserved for smaller items, such as cups and glasses. It’s recommended that your utensils are placed on the highest shelf when washing, but because you can have too many after cooking a large meal it’s important to look for a machine that offers top shelf flexibility. Bosch’s unique retractable VarioDrawer with third level offers even greater flexibility, so you can make the most of your dishwasher space and still get everything cleaned perfectly.
Dishwashers come in two main sizes: 45cm wide (slimline) and 60cm wide (standard), so you have a choice of options depending on your kitchen or utility space. Always measure the size of the space before purchasing a dishwasher and if you do need a slimline (45cm) model, check for versatile stacking options like Bosch’s VarioFlex drawers to make sure you get the most from the space available. And if you simply don’t have room for a dishwasher under your worktop, consider a compact counter-top dishwasher.
If you’re installing your dishwasher in a fitted kitchen, you might favour an integrated model to blend in with your units. On a fully integrated appliance, features like Bosch’s TimeLight enable you to check progress without opening the door, and Bosch OpenAssist allows you to open the door by just pressing on the panel. Freestanding dishwashers don’t need a fascia panel and so are quicker to install, with all controls easily accessible on the front of the appliance. Many Bosch models feature intuitive control panels, so it’s easy to get the right settings and to track progress.
There are many low-noise dishwashers available, but it’s important to check that these can still perform to a high level. Noise levels are important especially if you entertain in the kitchen. Look for dishwashers offering noise ratings of around 40-45db(A), and for special programmes like Bosch’s SuperSilence Plus, which reduces noise to only 38db(A).

How can I stop hand drying items when the dishwasher finishes?
Many dishwashers leave a lot of moisture behind when the washing cycle has finished, meaning you have to hand dry items before you put them away. Bosch’s unique PerfectDry feature uses natural Zeolith minerals to dry everything to perfection, including pans, glasses and even plastic items. All lunchboxes and containers will be perfectly dry and cupboard ready, so you'll never have to pick up a tea towel to finish the job again.

Bosch dishwashers with a built-in heat exchanger take perfect care of delicate glasses and porcelain. By pre-heating the water use in the rinsing tank, temperature shocks between hot water and cold water are avoided.
