Dishwasher Buyer’s Guide: How to Choose the Right Model

Choosing a new dishwasher can be a challenge given the vast array of models, sizes, and features available. Whether you're replacing an old appliance or buying a dishwasher for the first time, the decision directly impacts your daily routine, your electricity bill, and the convenience in your kitchen. This guide is designed to help you understand the technical specifications and features to make an informed choice that perfectly suits your needs and your household. We will present objective criteria and a selection of models for various requirements.

What to Look for When Buying a Dishwasher

Before you decide on a model, a few fundamental considerations are important. The following points will help you narrow down the selection and identify the features that are relevant to you.

1. The Right Type and Size: 60 cm, 45 cm, or a Tabletop Dishwasher?

The size of the appliance is often the first deciding factor and depends on the available space in your kitchen as well as the size of your household.

• 60 cm Dishwasher: This is the standard width for most fitted kitchens and the most common choice for families or households with three or more people. These models offer the largest interior space and typically hold 12 to 14 place settings.
• 45 cm Dishwasher: These slimmer models are an excellent solution for smaller kitchens, single-person, or two-person households. They typically hold 9 to 10 place settings and, despite their compact design, often offer the same range of functions as their larger counterparts.
• Tabletop Dishwasher: These compact appliances are placed on the countertop and often do not require a permanent water connection, as some models have an integrated water tank. They are ideal for students, small apartments, camper vans, or as a temporary solution.

2. Efficiency and Operating Costs: Energy Consumption and Noise Level

Two of the most important metrics on the EU energy label are the energy efficiency class and the noise emission.

• Energy-Efficient: The EU energy label ranges from class A (very efficient) to G (less efficient). An energy-efficient dishwasher with a good class like B or C will consume significantly less electricity and water in the long run, which lowers operating costs. The specified consumption refers to 100 wash cycles in the eco programme.
• Quiet Dishwasher: The noise level is specified in decibels (dB). A quiet appliance is crucial, especially in open-plan kitchens. A quiet dishwasher has a value of 44 dB or less. Models around 42 dB are barely perceptible. The noise emission class (A to D) on the label also helps with comparison.

3. Key Features: AquaStop and Smart Home Functions

Modern dishwashers offer a range of functions that increase safety and ease of use.

• With AquaStop: An AquaStop system is an indispensable safety feature. In the event of a leak or a burst hose, it immediately cuts off the water supply, reliably protecting against water damage. Many manufacturers provide a long warranty on this system.
• Smart Home: More and more appliances are Wi-Fi enabled and can be controlled via an app. This Smart Home connectivity allows you to start the wash cycle remotely, check the status, receive notifications, or download additional special programmes.

Frequently Asked Questions

What is more important: energy efficiency or water consumption?

Both values are relevant for long-term operating costs. The EU energy label assesses overall efficiency, with electricity consumption playing a larger role. Modern, energy-efficient dishwashers are generally also economical in water consumption, especially in the eco programme. A look at both figures on the energy label helps to find the most economical appliance.

How quiet is a "quiet" dishwasher?

A dishwasher is considered quiet with a value below 45 dB. For open-plan kitchens where living and cooking areas merge, models with 42 dB or less are recommended. These are barely audible during normal daily operation. The noise emission class on the energy label (A is the quietest) offers a quick comparison.

Does every dishwasher need an AquaStop?

While a dishwasher with AquaStop is not legally required, it is a very worthwhile investment in safety. The system reliably protects against costly water damage that can result from defects in the appliance or hose. Most brand manufacturers equip their appliances with it as standard and often provide a warranty on the system's function for the entire lifespan of the appliance.
