It may not be the primary function but drying your crockery and cutlery might in actual fact be more arduous for your dishwasher than cleaning them. Plates and cups have multiple nooks and crannies that could trap dishwater preventing it from drying out, and as your dishwasher cools down water condenses out of the steam.
Dishwashers also utilize a number of approaches to get your crockery and cutlery dry. Some will use a heating element to heat up the air in the dishwasher and help the water to evaporate, some warm the water more near the final rinse, certain models use a fan, and certain models have a mix of all of these. There are consequently a variety of explanations why your dishwasher could not be drying dishes optimally and a variety of options to improve the situation.
Plastic is less likely to dry fully 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 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 help you identify and rectify the issue.
Few things are more irritating than an appliance that doesn’t work as it’s meant to, regardless of whether its a tv, tumble dryer or dishwasher we expect them to do the job they were designed for. If you open the dishwasher to wet plates there are a number of places you can look to help you figure out the issue.
Not all makes and models are built to the same spec and some appliances do a better job of drying your crockery and cutlery than others. However, if if your dishwasher has always dried your crockery and cutlery in the past one of these areas could be the cause.
Sometimes there is nothing actually wrong with the dishwasher. Before assuming the appliance is faulty you should first check that you haven’t overloaded it or accidentally stacked items one inside the other. Also be aware that plastic items are more difficult to dry than metal, glass or ceramics.
Your dishwasher needs rinse aid to properly dry your dishes thus, if you’ve forgotten to top up or your rinse aid dispenser is broken this can result in wet plates at the end of the cycle.
Visually check the rinse aid dispenser for cracks and check that there is rinse aid inside.
Without enough heat your dishes will not dry so a not working heating element may be the explanation your machine is not working as it should. If your plates don’t feel hot to touch when they come out of the machine this can be a good indicator that the heating coil isn’t working as it should.
To check the heating coil you will need to disconnect the machine, find the heating element, you may need the manual to do this, and use a multimeter to check it’s working.
The thermostat stops your dishwasher overheating, adjusting the heat of the water and air during drying. However, if it’s broken this can result in your appliance not heating up at all.
If you check the heating element and do not discover an issue but there’s still no heat, then the thermostat may be at fault. Again you can make sure using a multimeter.
Many machines will make use of a fan and vent to suck moist air from the dishwasher. If the fan isn’t operating as is should or the vent is blocked then the steam will form droplets on the dishes instead leaving them wet.
You can make use of your manual to check if your dishwasher has a fan and find its location. Don’t forget to make sure the machine is unplugged before attempting to make repairs.
You can look at the fan and vent to check if there is anything lodged that might 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 variety of methods you can use to improve how well your machine dries your dishes and prevent you needing to dry them by hand as little as possible.
If this trouble shooting guide hasn’t worked it could be necessary to call in an engineer or perhaps buy a new dishwasher.
