16 Reasons Why Bosch Dishwasher Not Drying: Solutions

1. Dishes Are Overcrowded

If your dishes are coming out of the dishwasher wet, it could be because they’re overcrowded.

When there’s too much in the dishwasher, water can’t circulate properly and things don’t get as clean. Check to see if you need to adjust your racks or use a different cycle.

2. Unloading in the Wrong Order

Bosch dishwashers have a specific unloading order that ensures all items come out clean and dry. Dishes should be removed in the following order: top rack, middle rack, then bottom rack.

This unloading order is important because it allows dishes on the lower racks to benefit from the heat generated by the upper racks during the drying cycle.

3. Use More Powerful Drying Options

Some dishwashers have a “rinse only” setting that doesn’t include a drying cycle. If your dishwasher has this option, try using it and see if it makes a difference.

4. Add Rinse Aid for Better Drying

You can improve your dishwasher’s drying performance by adding rinse aid. This simple step can make a big difference in how well your dishes come out of the wash.

Rinse aid is a product that you add to your dishwasher’s detergent compartment. It helps to reduce the surface tension of water, which allows it to sheet off of dishes more effectively. This, in turn, helps the water to evaporate more quickly and prevents spots from drying onto your dishes.

If you have never used rinse aid before, start by adding a small amount to see how it affects your dishwasher’s performance. You can always add more if needed. Be sure to follow the manufacturer’s instructions for best results.

5. Plastic Items Are Still Wet

Bosch dishwashers have a special setting for plastic items. If your plastic items are not drying, make sure you have the right setting selected.

If the right setting is selected and your plastic items are still wet, there are a few things you can try. First, check the water inlet to make sure it is not blocked. Next, check the filters and make sure they are not clogged. Finally, check the drain hose to make sure it is not kinked or blocked.

6. Power Interruptions

If your dishwasher doesn’t seem to be drying dishes as well as it used to, one possible reason is that it’s not getting enough power.

Check to see if there have been any power outages or disruptions in service in your area recently. If so, that could be the problem.

7. Vent

One potential issue is the vent. Over time, the vent can become clogged with lint and other debris, which can prevent hot air from escaping and cause the dishes to come out wet.

To clean the vent, first remove the lower kickplate and then use a vacuum attachment to clear away any blockages. You may also need to use a brush to reach deep into the vent.

Once you’ve cleared the vent, replace the kickplate and run a test cycle to see if the dishes come out dry.

8. Vent Fan Motor

The vent fan motor is responsible for drawing air through the dishwasher during the drying cycle. If your Bosch dishwasher is not drying, the vent fan motor may be to blame.

This part is located near the top of the dishwasher and can be accessed by removing the top panel.

To test the vent fan motor, use a multimeter to check for continuity. If the motor is faulty, it will need to be replaced.

Replacing the vent fan motor is a relatively easy repair that can be completed in about an hour. Be sure to unplug the dishwasher before beginning this repair. You will also need a Phillips screwdriver and a putty knife.

9. Heating Element

The heating element is located near the bottom of the dishwasher and helps to dry the dishes. If your dishwasher is not drying, it may be because the heating element is not working properly.

Symptoms:

-Dishes are not getting dry

-There is water pooled at the bottom of the dishwasher

-The dishes are still wet after the cycle is finished

If you are experiencing any of these symptoms, it is likely that your dishwasher’s heating element is not working properly.

What to do:

-Check the heating element for signs of damage

-Test the heating element to see if it is working properly

-Replace the heating element if necessary

10. Heating Element Assembly

The heating element assembly is located at the bottom of the dishwasher. It helps to circulate hot air and water during the drying cycle. If your dishwasher is not drying properly, it may be due to a problem with the heating element assembly.

Replacing the Heating Element Assembly:

If you need to replace the heating element assembly, you will need to purchase a new one from a Bosch authorized service provider. Be sure to have the model and serial number of your dishwasher handy when you call, so they can help you select the correct part.

Installing the New Heating Element Assembly:

To install the new heating element assembly, follow these steps:

First, disconnect the power to your dishwasher by unplugging it from the outlet or flipping the circuit breaker.

Next, remove the lower dish rack and spray arm assembly.

Then, locate the heating element assembly at the bottom of the dishwasher and remove it.

Finally, install the new heating element assembly by reversing the above steps.

Once you have installed the new heating element assembly, your dishwasher should be able to dry dishes properly once again.

11. High Limit Thermostat

If your dishwasher isn’t drying dishes properly, one possible reason is that the high limit thermostat has tripped. This thermostat is a safety device that cuts off power to the heating element if the water in the dishwasher gets too hot.

To check whether this is the problem, first make sure that there is no blockage in the dishwasher’s drain hose or air gap. If these are clear, then the next step is to check the high limit thermostat.

To do this, you’ll need to remove the dishwasher’s control panel. Once you have access to the thermostat, use a multimeter to test it for continuity. If the thermostat is faulty, it will need to be replaced.

12. Thermostat

The thermostat in your dishwasher is responsible for regulating the water temperature. If it’s not working properly, your dishes won’t get clean and they definitely won’t be dried properly.

There are a few things that can cause your dishwasher’s thermostat to stop working:

-A faulty heating element

-A build-up of lime scale

-A problem with the washing cycle

How to fix it?

If your dishwasher’s thermostat is not working, you’ll need to call a repairman. However, there are a few things that you can try to fix it yourself:

-Descale the heating element: This will remove any build-up of lime scale and should help the thermostat to work properly again.

-Check the washing cycle: Make sure that the dishwasher is on the correct cycle. If it’s not, this could be causing the thermostat to malfunction.

-Replace the heating element: If the other two options don’t work, you may need to replace the heating element. This is a more complex repair and should only be attempted if you’re comfortable with appliance repairs.

13. Control Board

The control board is the brains of the dishwasher. It tells the various components what to do and when to do it. If your dishwasher isn’t drying, it could be because the control board is faulty.

How to fix it:

If you’re comfortable working with electronics, you can try replacing the control board yourself. Otherwise, you’ll need to call a repairman.

Replacing the control board is a fairly simple process. First, make sure that you have the correct replacement board. Then, remove the old board and install the new one. Once the new board is in place, test your dishwasher to see if it’s now drying properly.

14. Control Module

The control module is the dishwasher’s brain. It is a small computer that controls all the functions of the dishwasher. If the control module fails, the dishwasher will not work.

Why does it fail?

There are many reasons why the control module can fail. The most common reason is a power surge. A power surge can damage the control module and other electronic components in the dishwasher.

What are the symptoms of a failed control module?

The most common symptom of a failed control module is that the dishwasher will not start. Other symptoms include the dishwasher not running, the dishwasher not draining, and the dishwasher not drying.

How do you replace a control module?

Replacing a control module is a difficult and expensive repair. The best way to avoid this repair is to have the dishwasher serviced by a qualified technician before the control module fails.

15. Main Control Board

The main control board is the heart of your dishwasher. It controls all the other components and makes sure they are working properly. If your dishwasher is not drying, it could be because the main control board is not functioning correctly.

You will know if the main control board is not working if your dishwasher does not start, if it does not fill with water, or if the cycle does not advance.

How to fix it?

If the main control board is not working, you will need to replace it. You can find the replacement part at your local appliance store or online.

Replacing the main control board is a fairly easy repair that you can do yourself. Just make sure to unplug your dishwasher before beginning the repair. Then, follow the instructions in your owner’s manual to remove the old board and install the new one.

16. Timer

The most common reason is that the timer is not set correctly. Check to see if the timer is properly set and if it is, try resetting it. If that doesn’t work, then there may be an issue with the dishwasher itself. In that case, you’ll need to call a repairman.

Bosch dishwasher turn off dry cycle?

There are a few potential causes for this, and fortunately, there are also a few easy solutions.

One common cause for a Bosch dishwasher to turn off its dry cycle is simply because the load isn’t completely dry yet.

This usually happens when there are big or oddly shaped items in the load that impede air circulation and prevent the dishes from drying completely. To fix this, simply remove the items that are preventing proper air circulation and run the dry cycle again.

Another potential cause for a Bosch dishwasher to turn off its dry cycle is because the heating element isn’t working properly. This can be caused by a number of things, including a blown fuse or tripped circuit breaker. To fix this, simply check the fuse box and reset any blown fuses or tripped circuit breakers.
