Dishwashers: Mistakes to Avoid When Buying

In depth

Measuring your space accurately is the single most common cause of dishwasher disappointment. It’s easy to get carried away browsing online, imagining how beautifully everything will fit, but it's far too simple to just assume a 60cm appliance will magically slot into every kitchen. Before you even start looking at models, measure the available width, height and depth *within* your cabinetry. Don’t simply measure the external dimensions of your units; account for any infill panels or spaces where pipes might run – these can easily add an extra 5-10cm to the overall space needed. Furthermore, consider the door swing. Dishwashers require clearance around their doors to open fully, and a narrow doorway can cause significant frustration, especially when loading and unloading. Take detailed measurements of the area you're considering, sketch out your kitchen layout, and then use that as your guide when researching models. It’s worth also checking the manufacturer’s specifications carefully for dimensions – don’t just rely on online listings which may not always be entirely accurate.

It’s tempting to get drawn in by the latest innovations and features offered by dishwashers, but often these are expensive additions that you simply won't use. Many models boast steam cleaning cycles, folding arms, or even built-in water filters, all of which add considerably to the purchase price. Before you start considering these extras, ask yourself if you’ll actually utilise them regularly. A small household probably doesn’t need a dishwasher with ten different wash programs; most people will be perfectly happy with a standard ‘intensive’ cycle. Similarly, a folding arm is convenient but adds to the cost and complexity of repairs should something go wrong. Focus on the core features you genuinely need – a good temperature control, decent spray arms, and effective drying capabilities – and stick with those.

Running costs can represent a significant ongoing expense for a dishwasher, often overlooked in initial calculations. While energy-efficient models are becoming more common, it’s important to understand their actual water consumption. Dishwashers use considerably more water than handwashing, and the amount of water used per cycle varies greatly between models. Pay close attention to the manufacturer's specifications – look for an appliance with a low kWh/cycle rating and a good Water Factor (the lower the better). Also, consider your household size; a larger family will naturally use more water and energy than a single person. Finally, factor in the cost of detergent – high-quality dishwasher tablets can be considerably more expensive than handwashing liquids.

Beyond the initial purchase price, there are often hidden costs associated with installing a dishwasher that you need to consider. Most kitchens require an additional electrical circuit dedicated solely to the appliance, and this may necessitate hiring an electrician to install it safely. Plumbing work is also frequently required – a cold water supply connection and a drain hose must be fitted, which could involve modifications to your existing plumbing. Don’t forget the cost of any necessary accessories such as a rinse aid dispenser or a cutlery basket. Get multiple quotes from qualified plumbers and electricians before committing to a purchase to avoid unexpected expenses.

The specification of a dishwasher isn't necessarily indicative of its performance in a typical home environment. Marketing departments are skilled at highlighting impressive figures – maximum wash temperatures, pressure levels, and cycle durations – but these rarely translate into tangible benefits for the average user. A dishwasher with a 90°C wash temperature might be fantastic for heavily soiled items, but you likely won’t use it regularly. Similarly, high-pressure spray arms are overkill for everyday cleaning, and lengthy cycles can waste water and energy. Focus on features that genuinely improve your washing experience – effective stain removal, quiet operation, and reliable drying – rather than chasing impressive specifications.

Don't be swayed by clever marketing terms or overly enthusiastic reviews focused solely on a few standout features. Read independent customer feedback carefully, paying attention to recurring themes about reliability, noise levels, and ease of use. Many online reviews are influenced by promotional offers or biased opinions; try to find reviews from users who genuinely reflect your own household size and cleaning habits. Consider the manufacturer’s reputation for quality and after-sales service – a well-known brand with a strong warranty may be a safer investment in the long run than an unknown one.

Finally, always thoroughly research the retailer's returns policy before making a purchase. While Amazon UK offers generous return options, understanding the timeframe and conditions (e.g., proof of purchase) is crucial. Ensure you’re comfortable with the process should you need to return the dishwasher for any reason – this can be particularly important if you’ve had to arrange professional installation. Keep all original packaging and documentation safe, as these are typically required as part of the returns process.
