It may not be the primary function but drying your crockery and cutlery might in actual fact be more difficult for your machine than getting them clean. Plates and glasses have lots of nooks and crannies that could collect water making it more difficult for it to evaporate, plus as your appliance loses heat water condenses from the humid air.
Different machines also employ a number of different approaches to dry your plates. Some will employ a heating element to heat up the air in the machine and assist with evaporation, some warm the water further near the final rinse, some make use of a fan, and certain models employ a mix of all of these. There are thus a variety of explanations why your dishwasher might not be drying plates fully and a number of things you can do to improve the situation.
Plastic is more difficult to dry than other materials as it doesn’t retain heat in the same way which helps with the drying process, so it’s worth noting whether the drying issue is related to the material rather than the machine.
If your dishwasher isn’t drying effectively you can call a dishwasher repair service or first make use of this troubleshooting list to figure out what the issue is and with any luck fix it.
There is nothing more irritating than an appliance that doesn’t work as it should, whether that’s a smartphone that really isn’t being that smart, a washing machine that’s churning out dirty clothes, or a dishwasher that is either not cleaning or drying your crockery and cutlery. If you open the dishwasher to wet plates there are a few places you can look to help you figure out the issue.
Not all appliances are built to the same spec and some makes and models do a better job of drying your dishes than others. But if if your dishwasher has always dried your crockery and cutlery in the past one of these faults may be the problem.
Sometimes there is nothing actually wrong with the appliance. Before assuming the appliance is faulty you should look at how it has been stacked, ensuring it isn’t too full. Also be aware that plastics are more difficult to dry than metal, glass or ceramics.
Your appliance needs rinse aid to properly dry your crockery and cutlery thus, if you’ve forgotten to top up or your rinse aid dispenser is not working this can result in wet dishes at the end of the cycle.
Visually inspect the dispenser for damage and ensure that there is rinse aid inside.
Heat is essential for drying your dishes so a broken heating element could be the reason your machine is not working as it should. If your dishes don’t feel hot to touch when they come out of the machine this can indicate that the heating coil isn’t working as it should.
To inspect the heating element you will need to unplug the appliance, find the heating coil, you may need the manual to do this, then check for continuity using a multimeter.
The thermostat ensures your dishwasher doesn’t overheat, determining the heat of the water and air during drying. Therefore, if it’s not working this can result in your appliance not heating up at all.
If the heating element appears to be working as it should but there’s still no heat, then the thermostat could be at fault. Once again you can check this with the help of a multimeter.
Many dishwashers will use a drying fan and vent to remove the warm moist air from the appliance. If either of these elements are faulty then the water vapor will condense on the plates instead preventing them from drying.
You can make use of your manual to find out if your dishwasher uses a fan and find its location. Don’t forget to double check the machine is unplugged before attempting to access the fan.
First look at the fan and vent to see if anything is blocking it that would stop it from functioning as it is supposed to. If there is nothing obvious you can then test for continuity using a multimeter.
There are a number of methods you can use to boost your dishwashers drying ability and prevent you needing to dry them by hand as infrequently as possible.
If you have checked all the above it could be necessary to call in an engineer or even replace your machine.
