If your dishwasher won’t stop running, there is a fault with your machine that is causing this issue.

Follow the entire guide to learn the way to fix this problem in minutes!

The Bosch Dishwasher keeps running due to a variety of reasons, such as a Blocked Filter and Drain Hose, a faulty Air Vent, a dirty Wash Sensor, and Cold Water. The solution simply requires a thorough inspection and cleaning of a few dishwasher components.

Let’s learn how to resolve your long-running Bosch dishwasher issue!

How To Fix When Bosch Dishwasher Keeps Running?

If your dishwasher’s wash cycle is taking longer than it used to, there is likely a problem with some of the components responsible.

Fortunately, this issue is simply fixable, but you must be sure to follow each step precisely to avoid missing anything essential.

Note: Newer Bosch Dishwashers use less water and power, which is why their wash cycle is longer.

Is Rinse Aid On?

The rinse aid’s status, such as whether it is ON or OFF, also affects how long the dishwasher will run.

Additionally, it is essential that the dishwasher has enough rinse fluid.

Consequently, turn on the rinse aid before choosing the appropriate cycle speed, such as VarioSpeed Plus.

In case nothing works, start applying the solutions below!

Solution #1 Clean Drain Filter!

The dishwasher filter gets clogged with dirt often, which causes the filling and draining of the machine to take a long time.

Indirectly, this results in a longer wash cycle, and your dishwasher won’t stop until the cycle is finished. 

So, even if your dishwasher has a self-cleaning filter, you still have to clean it manually!

Here is how you can clean the dishwasher’s filter:

1. Unplug your Bosch Dishwasher from the power source!
2. Open the Dishwasher Door and pull out the Lower Rack.
3. Hold down the Spray Arms and pull them up to remove them.
4. Rotate the Drain Filter counterclockwise to remove it.
5. Next, lift out the Square Mesh Filter from the basin.
6. Make soapy water and clean both filters with water.
7. Also, use an old toothbrush to properly unclogged debris from the filters.
8. Try to wash the filters with warm water.
9. Put the filter back by rotating it clockwise to lock it.
10. Then place the mesh panel and then spray the arms back to their places.

Tip: Do not run the wash cycle before inspecting other components because if the problem exists, you will have to wait for the cycle to complete.

Solution #2 Unclog Drain Hose!

The dishwasher fills and drains water from the hose.

There might be a possibility that your machine’s hose is clogged, and that’s why it is taking longer than usual to complete the cycle. 

The drain hose is one of the primary reasons why the Bosch Dishwasher won’t stop running!  

Solution: Inspect the drain hose, so you can unclog or replace it depending on its condition!

Here is how you can access your dishwasher’s drain hose:

1. Switch OFF the Water and Power Supply of your Bosch unit. 
2. Open the door, and remove the door screws that hold the outdoor panel.
3. Close the door and remove the outdoor panel from the unit.
4. Then unscrew the junction box and disconnect its wires.
5. Next, remove Strain Relief from the bracket.
6. Now remove the Drain Hose from the sink and pass it from the cabinet. 
7. Open the unit door and unscrew the mounting screws from the top.
8. Remove the leveling leg locking screws from the bottom. 
9. Adjust the legs to lower the dishwasher.
10. Carefully pull out the dishwasher from the cabinet.
11. Disconnect the Drain Hose from the dishwasher back.

Inspect the hose for breakage. If there is no leakage, then it’s time to clean it. Wash the hose under warm water to soften clogged debris.

Next, take a brush to clean the hose and then wash the component as well. Test the hose by connecting it to the tap to ensure no leakage.

Solution #3 Clear Air Vent

Aside from cleaning the dishwasher filter and hose, it is crucial to maintain the air vent of your unit.

It’s possible that your dishwasher’s air vent is blocked or broken and that’s what’s causing the dirty water to be redirected, which then indirectly causes the water to take longer to drain. 

Solution: All you need to do is clean the dishwasher's air vent.

Here is how you can clean the dishwasher air vent:

1. Locate your dishwasher Air Vent near the dishwasher sink.
2. Pull the Vent Cap off and then unscrew the other cap of the vent.
3. Next, pull off the rectangular cap to access the vent.
4. Take a twisted brush and try to clean the debris from it properly.

With all solutions until the start, you should now perform a test to check whether your Bosch Dishwasher will keep running for longer.

Tip: Keep your dishwasher clean by servicing it at least twice a year!

Solution #4 Clean The Dishwasher

Most of the time, an excess of minerals in the water can generate layer accumulation on the unit dishwasher and some of the components, which are often difficult to remove.

There is a chance that the dishwasher and its components have a buildup layer that is invisible but is preventing the system from operating properly.

All you have to do is effectively clean the dishwasher.

Here is how you can clean the dishwasher from buildup:

1. Take out dishwasher racks and utensils from the unit.
2. Select the temperature to Maximum and pour the bowl of white vinegar!
3. Run the longest wash cycle and let it clean properly.
4. Add a dishwasher detergent to the unit and leave it for 10 minutes.
5. Scrub the dishwasher and its components, by using a damped sponge in soap.
6. Again, run a new wash cycle to clear up all the build-up from the unit.

Tip: Regularly clean your dishwasher with vinegar or detergent to avoid this buildup!

Solution #5 Configure Unit Heater

For the Bosch dishwasher to operate correctly, the water must be at the proper temperature.

If the water isn’t heating up quickly, there’s a chance that your dishwasher’s heater or heater relay has a fault.

In this way, the water must first be heated before the dishwasher can begin to clean. 

Solution: Test your dishwasher heaters to see if they are functioning correctly.

Here is how you can configure your dishwasher heater:

1. Turn OFF your dishwasher from the Power and Water Connection.
2. Use your product manual to get access to the unit heater.
3. When you get access, then test the heater using a multimeter.
4. Connect meter probes end with the heater ends and check for continuity.

If there is inappropriate continuity, then replace your dishwasher heating element.

Is Your Dishwasher Water Pressure Good?

Water pressure greatly influenced your dishwasher’s effectiveness. The reason why your dishwasher takes so long to complete a cycle may be because the water is filling too slowly because of low pressure.

This is based on the water line, and not on the machine’s end.

Run a test to check your home Water Pressure. Close all of your household taps and then completely open the kitchen tap.

Check the pressure by connecting a Pressure Gauge. 

The recommended psi Bosch DIshwasher is between 50 and 60!

Quick Recap:

When your Bosch Dishwasher won’t stop running, you must first clean the Filter, Hose, Spray Arms, Air Vent, and dishwasher itself with detergent. In order to prevent the dishwasher from running longer than usual, you’ll need higher water pressure!
