Bosch dishwashers are some of the most reliable dishwashers in the market. However, they are still susceptible to breakdowns and other issues from time to time. This troubleshooting guide will make it easy to resolve any problems your Bosch dishwasher may experience.
How do you reset a Bosch dishwasher?
Dishwasher resetting is essential for canceling cycles or fixing an operational problem. The easiest way to reset your Bosch dishwasher is by pressing the On-Off button for at least 10 seconds. This should stop the complete operation.
Bosch dishwasher buttons are located atop the dishwasher door or on the door’s front panel, depending on the model you have. There are two main ways to reset a Bosch dishwasher;
Resetting using the ‘cancel drain toggles’
This method resets the dishwasher by preemptively completing a cleaning cycle. To reset using this method;
- Open the doors slowly to see the control buttons.
- Press the “Cancel Drain” button slightly for about 3 seconds.
- Then close the door gently and give it around 1 minute to make sure the cycle is well completed.
- Re-open the door and press the “ON/OFF” button.
- The reset cycle is complete.
Resetting the Bosch Ascenta Model
This model has a child lock feature for increased safety. You will have to turn off the child lock feature before you can reset the dishwasher.
- Press the “<” button until the label “CL” disappears from the screen.
- Open the Ascenta dishwasher door gently to see the button inside written “START RESET.”
- Hold the button down until the “ACTIVE” LED is gone.
Note: For the SHE5AM model of the Bosch dishwasher, the display clock turns to “0:00” when the reset is complete. Always refer to your user manual for further clarification.
Why is my Bosch dishwasher not starting?
If your dishwasher doesn’t start up when you turn it on, it may have power issues or an operational issue. Here are the main reasons why your dishwasher is not starting;
- The dishwasher is not getting a power supply due to a blown fuse or damaged wire connection. Check for continuity using a multimeter, then hire a licensed electrician to fix the issue.
- The dishwasher door is not fully closed. The dishwasher door latches are fitted with sensors that control the dishwasher when a door is opened. They automatically turn off the dishwasher whenever the door is opened.
- The dishwasher has not been programmed to clean. Ensure that you have selected a cleaning cycle. The cycle selector instructs the machine on the operation required. Also, ensure that the machine settings are not hindering its operation.
- The dishwasher may have a faulty timer. The timer is vital for controlling the cycle and the power used to run the dishwasher. Inadequate distribution of power to the various parts of the dishwasher will prevent it from starting.
- Check for clogs as this may also prevent the dishwasher from working.
- The dishwasher may have a faulty motor. If all the other components are working correctly, hire a professional to see if the motor needs repair or replacing.
- Water supply is another cause of this issue. The dishwasher cannot run if there is a water supply hiccup. Ensure the water valve is turned on and connected to the water supply.

Bosch dishwasher not draining
If your dishwasher is not draining, check the filter and pump and see if they are clogged. To do this;
- Remove the filter and clear any debris and objects that are trapped in the filter.
- Clean the filter using soap and a soft brush under running water.
- Before reinstalling the filter, remove the pump cover and remove any debris in the pump.
- Use caution as some debris may be sharp.
- Then reinstall the pump cover and filter.
Note: Always refer to your user manual when opening or disassembling parts of your dishwasher.

Bosch dishwasher not cleaning
Having dirty dishes at the end of the cleaning cycle can be extremely infuriating. This means your dishwasher is not cleaning dishes as it should. Here are some steps you can use to ensure your dishwasher cleans your dishes properly;
- Load the dishes strategically to ensure there is sufficient space between items. This will ensure they are all properly cleaned. Also, ensure the spray arms can move freely after loading the dishwasher.
- Do not pre-rinse your dishes before loading. Just scrape the food off the dishware. The dishwasher detergent needs small food debris to cling to work properly.
- Add rinse aid to the dishwasher. It helps water droplets slide off dishware so you can’t see watermarks. Refer to your owner’s manual to learn how to use rinse aid.
- Clean your dishwasher’s spray arms to prevent clogging. Run them underwater to see if any of the holes are blocked. You can use a toothpick to loosen any debris caught in the holes.
