After crunching the numbers from our survey, we were able to identify the most common dehumidifier issues.
Why has my dehumidifier stopped working? - Which? News
A sizeable 14% of dehumidifier owners who told us about their faulty machine said the problem was a broken auto function or humidistat. This EcoAir model can extract up to seven litres of moisture per day, and as a desiccant-type dehumidifier, it works at lower temperatures than your average refrigerant device. Looking after your dehumidifier properly should ensure trouble-free operation for years. As parts begin to deteriorate with wear and tear, replace them to avoid having to buy a completely new device. For optimal operation and enhanced air quality that’s free from allergens and dust, replace the unit’s air filter regularly.Don’t get too excited about this dehumidifier’s smart capabilities. You can connect it to your smartphone or tablet via Bluetooth, but the app is little more than a glorified remote control with only basic scheduling features and no way to integrate with existing air quality meters you might have hooked up. That aside, it’s a well-designed and effective dehumidifier, capable of extracting up to 20 litres per day into a larger-than-average six-litre tank. We found this surprisingly easy to remove from the rear of the machine when full, with a built-in handle for carrying. All dehumidifiers do the same basic job of removing excess moisture from the air. However, there are three different technologies that do all the hard work. Empty your dehumidifier regularly You'll definitely want to empty it before putting it away for storage. Wipe the tank with a cloth. Water that has been left to stagnate can develop mould and mildew. If that doesn’t solve your problem, it’s possible thatthe fan motor or compressor may be broken or faulty. Your compressor is the pump in the device that circulates coolant throughout your machine’s evaporator, which leads to the removal of moisture from the air. When asked about their dehumidifier troubles, 10% of owners told us they were dealing with leaks: 5% from the water tank, 5% from elsewhere.

Peltier dehumidifiers also cool the air and condense the moisture content into water, but they do it using a cold heat-sink rather than a compressor. They’re not as effective as compressors, removing smaller amounts of water in a given time, but they’re quieter and more energy-efficient. Peltier dehumidifiers tend to be compact, lightweight units designed for smaller spaces. Try to position your dehumidifier in the centre of the room Don't position the machine right next to walls, curtains or furniture.A dehumidifier should turn itself off once the water tank is full so that it doesn't overflow. It should start up again once you've emptied and refitted the tank, assuming you've refitted the tank correctly.

Dehumidifiers don’t have to be noisy, and there are some good near-silent options. They will work discreetly in your home without interfering with your sleep or work, so a quiet mode or eco mode is well worth any extra, particularly if it will save you some cash in running costs. If you've invested in a good dehumidifier, it might achieve your target level of relative humidity sooner than you were expecting, which might make you think it's not doing its job. Cleaning your dehumidifier's filter can make a difference to noise levels as, over time, dirt and dust can gather inside the machine. In extreme cases, the compressor or fan motor might need replacing entirely. Keep it running all day long and the costs could mount up, but this is an excellent dehumidifier for situations where a refrigerant model just won’t work. To keep your dehumidifier running longer and at its most effective, have a read through our top tips below:Compressor dehumidifiers work in much the same way as a fridge or freezer. They draw in air and cool it, condensing any moisture as it passes across a refrigerated coil. The water then drips off into a water tank below, while the air is reheated and released into the room. Compressor dehumidifiers can be noisy and may use more energy than other types, although new compressor technology and refrigerants are bringing improvements on both counts. They’re most efficient at warmer temperatures of 20°C and above, and your best bet if you need to remove lots of moisture from a larger space. When you can’t fix your dehumidifier yourself, call a professional first before taking it to a repair center. It’s likely the expert will know what the issue is from your description and can give you a quote. Depending on the quote, you can decide if it’s worth fixing the unit or it makes more sense to just buy a new one. A complete failure was the most commonly recorded issue. A broken auto function or humidistat, uncomfortable noise levels and leaky water tanks were among the other problems raised. However, it’s worth looking out for newer and more energy-efficient designs. For example, Meaco’s MeacoDry Arete One 20L costs around 6p per hour to run, based on an electricity rate of 28.3p per kWh, while some models will cost significantly more at the same rate. Use your dehumidifier daily for a couple of hours and the difference soon mounts up.
