It may not be the primary function but drying your plates could in actual fact be more difficult for your dishwasher than getting them clean. Plates and glasses have lots of crevices that may trap water stopping it from drying out, and as your machine cools water droplets form from the steam.
Different machines also employ a number of different means to dry your plates. Certain models opt for a heating coil to heat up the inside of the machine and assist the water to evaporate, some warm the water further near the final rinse, some use a fan, and certain models employ a mix of all three. There are consequently a number of explanations why your machine could not be drying plates optimally and a variety of options to improve the situation.
Plastic is less likely to dry fully than glass or ceramics as it cools down more quickly hindering the drying process, so it’s worth taking note whether the items that aren’t drying are predominantly plastic items.
If dishes are coming out wet you can hire a dishwasher repair service or first make use of this troubleshooting guide to figure out what the problem is and with any luck fix it.
Few things are more annoying than an appliance that isn’t working 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 removing the dirt from or drying your crockery and cutlery. If you open the dishwasher to wet plates here are a few places you can look to help you figure out the problem.
Not all dishwashers are created equal and you will find that some dishwashers do a better job of drying your dishes than others. However, if if your dishwasher has always dried your crockery and cutlery in the past one of these areas may be the problem.
It might be that there is no fault with the machine. Before assuming the machine is faulty you should look at how it has been loaded, ensuring it isn’t too full. It’s also worth noting that plastics don’t dry as well as metal, glass or ceramics.
Your appliance needs rinse aid to properly dry your plates and so if you have run out of rinse aid or the rinse aid dispenser is broken this can mean wet dishes at the end of the cycle.
Visually check the rinse aid dispenser for damage and ensure that there is rinse aid inside.
Heat is essential for drying your dishes so a not working heating coil might be the reason your appliance is not working as it should. If your crockery and cutlery aren’t hot at the end of the cycle this can be a good indicator that the heating element is faulty.
To check the heating coil first unplug the appliance, then find the heating coil, you might need the owners manual to do this, and check for continuity using a multimeter.
The thermostat prevents your dishwasher overheating, regulating the temperature of the water and the drying part of the cycle. Therefore, if it’s faulty this can result in your dishwasher not heating up at all.
If the heating element appears to be in working order but there’s still no heat, then the thermostat could be at fault. Once again you can check this using a multimeter.
Many appliances will use a fan and vent to remove the warm moist air out of the dishwasher. If the fan isn’t operating as is should or the vent is blocked then the steam will condense on the crockery and cutlery instead preventing them from drying.
You can make use of your instruction manual to find out if your appliance uses a fan and locate it. Again you need to ensure the machine is unplugged before trying to make repairs.
First visually inspect the fan and vent to check if there is anything lodged that might stop it from working correctly. If there is nothing obvious you can then test for continuity using a multimeter.
There are a number of things you can do to improve 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 perhaps upgrade your machine.
