Your Dishwasher Is Not Drying Completely

Why isn't anything dry when the dishwasher cycle is over? Is it a problem that can be easily solved? The answer is yes! Thanks to this article, you can identify exactly the element or elements causing this issue.

THE POSSIBLE CAUSES FOR THIS FAULT :

• The dishwasher is not properly plumbed in

• The programme isn't suitable

• All-in-one tablets shouldn't be used

• The detergent dispenser is defective

• The heating element is defective

• The temperature sensor is out of action

• The thermostat is defective

• The electric wiring is damaged

• The programmer is broken

• The motherboard is faulty

WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.

The dishwasher is not properly plumbed in

It may be the case that your dishwasher is not plumbed in properly and there is a siphoning issue. If your dishwasher's drain hose is set too far into the trap of your plumbing, then the water will drain too quickly out of your dishwasher. This results in the water flowing into the dishwasher then being drained off via a siphoning process. The water thus continues flowing for a very long period of time. Where this is the case, your appliance will either go into fault mode or cancel the washing and drying cycles and end the programme, without displaying an error code and without heating up. To avoid this problem, we recommend raising the drain hose and fixing it in place using the bracket supplied with your dishwasher. Don't forget that your drain hose should be inserted no more than 10cm into the stand pipe, which itself must be at least 65cm above the ground.

The programme isn't suitable

An unsuitable washing programme can deactivate the drying cycle. This may be the case if you use the pre-rinse or fast programmes, etc. We advise you to refer to the programme table in the manufacturer's handbook. If you're using an eco programme, there won't be as much drying because these programmes operate on a low temperature.

All-in-one tablets shouldn't be used

All-in-one tablets were designed to make life easier for us. You don't have to buy any more salt, rinse aid and it's also cheaper. The only problem with adding a rinse aid to the tablet is that the rinse aid doesn't get released at the right point in the cycle. This is because the release time for the rinse aid is set by your dishwasher's manufacturer. By using an all-in-one tablet, it is possible for the rinse aid to dissolve too quickly, meaning nothing gets dried properly. On certain dishwashers there is is a special programme for all-in-one tablets. For all other dishwashers, we advise you to use separate rinse aid, detergent and salt.

The detergent dispenser is defective

Your dishwasher's dispenser allows the detergent and rinse aid to be released at the right time in the cycle you have programmed. If the dispenser is defective, the rinse aid doesn't get released at the right time and nothing will get dried as well.

The heating element is defective

The heating element heats the water inside your dishwasher. If it is defective, the water won't be hot enough in the final rinse and won't dry anything properly. You can test the heating element using a multimeter in ohmmeter mode. Unplug the connectors from the heating element and put both of the tester's contacts on the terminals. If there is no continuity, you will need to replace it.

The temperature sensor is out of action

The temperature sensor enables the motherboard to monitor the temperature of the water. If it is faulty, the temperature may change and the water may or may not dry everything in the dishwasher.

The thermostat is defective

The thermostat enables the appliance to heat to a specific temperature. If the thermostat is defective, the right temperature cannot be reached and the appliance will not heat up.

The electric wiring is damaged

All the functional parts of your dishwasher are connected by electrical wiring. These can degrade due to either heat from the electric current or due to mechanical causes if they get folded, bent or cut. If this happens, and the heating wires have become detached, your dishwasher will not heat up. These wires most often end up getting cut at the door hinge. If you need to replace them, be careful when removing them as dishwasher doors can very easily cause cuts.

The programmer is damaged

The programmer is fitted with a number of small electrical contacts. If these contacts get damaged, this can prevent certain components on your dishwasher, such as the heating element for example, from being supplied with power. If this is the case, your appliance will no longer be able to dry the items placed inside it. Check the condition of this part and replace it if necessary.

The main circuit board is faulty

The main circuit board manages all your dishwasher's functions (motor, heating, water, etc.). It controls whether or not your appliance heats up and dries your crockery, cutlery and utensils, etc. If all the other parts mentioned above have been checked, it could be that the control module needs to be replaced. You can either do this yourself or call on the services of a manufacturer-approved engineer.
