Why Does the Dishwasher Not Drying Dishes Well?

Why Does the Dishwasher Not Drying Dishes Well?

The dishwashing cycle is over, you open the door of your “assistant” and … you find there wet and still dirty dishes. The situation, of course, is unpleasant, but not critical – such breakdowns can be fixed by a professional quickly enough. But first, let’s look at the problem, it is possible that the intervention of the master is not required at all.

If small drops of water remain on a metal dish, and at the same time it is clean, we hasten to please you – everything is in order with your “dishwasher”. The fact is that most models of dishwashers use condensation drying, which is not ideal. The principle of its operation is as follows: at the final stage of washing, the dishes are rinsed with hot water, which then begins to evaporate and settle on the metal parts of the machine body. Utensils made of metal, unlike ceramics and glass, cool down at the same rate as the inside of the dishwasher, and therefore water also condenses on it. Unfortunately, this can only be dealt with. In rare cases, droplets can also be found on other dishes (ceramic or glass).

If all the dishes are frankly wet and, moreover, dirty, your dishwasher has really broken down. Possible causes of the malfunction are described below.

Breakdowns due to which the dishwasher not drying the dishes

Most drying problems are closely related to heat. If heating does not occur, then

  • in machines with a condensation type of drying, water will not evaporate from the dishes;
  • in dishwashers with a turbo dryer, the fan, due to which drying occurs, does not pump hot, but cool air.

In both cases, the dishes remain wet. Therefore, breakdowns in case of problems with drying dishes are similar to malfunctions when the dishwasher does not heat water, and poor-quality dishwashing is a pronounced additional sign.

You can try to diagnose the type of failure of your unit yourself using our table. It lists the most common malfunctions that are typical for popular models of dishwashers.

Possible problem

The dishwasher does not dry, does not heat water, and does not clean dishes well

Faulty heating element (heating element)The heating element (and in some models the instantaneous water heater) is responsible for heating the water and drying the dishes. If it “burns out”, and this often happens due to scale, then the dishwasher does not heat the water and does not dry the dishes.

The heating element needs to be replaced.

The thermostat has failedThermal sensor – a temperature sensor or a temperature sensor that measures the temperature and sends information to the control module, and he already gives the command to the heating element to heat water or dry. If the sensor fails, the control module does not receive information and does not issue commands, respectively, the dishwasher does not dry the dishes

The temperature sensor needs to be replaced.

Dishwasher won’t start drying cycle Control module failureThe control module is one of the most important elements of the dishwasher. It distributes program commands to other nodes, for example, “take water” or “drain water”. If the control module fails or starts to work incorrectly, the dishwasher may not dry the dishes.

The module needs to be reprogrammed or completely replaced.

No fan sound or unusual noises are heard during turbo dryer
(only for machines equipped with turbo dryer)
Turbo fan failedIn models of dishwashers with a turbo dryer, a fan directs hot air onto the dishes, which dries them. If the fan fails, the dishes remain wet.

Fan replacement required

If it seemed to you that among the described malfunctions you found exactly what exactly matches your situation, it’s time to call the warranty service center (if your dishwasher is under warranty) or contact a private workshop. Do not try to fix the breakdown yourself: it is highly likely that the elimination of the consequences of an incompetent repair will end up costing even more than turning to professionals.
