What To Know
- The drain filter is located at the bottom of the dishwasher and can become clogged with food particles and debris.

If you’re facing the frustrating issue of your Bosch dishwasher flashing and refusing to start, you’re not alone. This common problem can be caused by a variety of factors, ranging from minor glitches to more serious underlying issues. In this comprehensive guide, we’ll delve into the potential reasons why your dishwasher is misbehaving and provide step-by-step troubleshooting tips to help you resolve the problem.
Understanding the Dishwasher’s Display
Before we dive into the troubleshooting process, it’s important to understand the different lights and error codes that your Bosch dishwasher may display. The most common flashing light is the “Check Water” indicator, which typically signals an issue with the water supply or drainage system. Other flashing lights may indicate problems with the heating element, circulation pump, or other components.
Troubleshooting the Water Supply
One of the most common reasons why a Bosch dishwasher won‘t start is a lack of water supply. Here are some steps to check:
- Ensure the water supply is turned on: Check the water valve under the sink to make sure it’s open.
- Inspect the water hose: Look for any kinks, leaks, or blockages in the hose that connects the dishwasher to the water supply.
- Clean the water inlet valve: Over time, sediment can accumulate in the water inlet valve, blocking the flow of water. Use a small brush or pipe cleaner to gently clean the valve.
Resolving Drainage Issues
If the water supply is没问题, the problem may lie with the dishwasher’s drainage system. Here’s what to do:
- Check the drain hose: Make sure the drain hose is not kinked or clogged. If necessary, disconnect the hose and clean it out.
- Inspect the drain pump: The drain pump is responsible for pumping water out of the dishwasher. If it’s not working properly, water will accumulate and prevent the dishwasher from starting.
- Clean the drain filter: The drain filter is located at the bottom of the dishwasher and can become clogged with food particles and debris. Remove the filter and clean it thoroughly.
Addressing Heating Element Problems
If the water supply and drainage system are functioning correctly, the problem may be with the dishwasher’s heating element. Here are some troubleshooting steps:
- Check the heating element: The heating element is located at the bottom of the dishwasher and is responsible for heating the water. Use a multimeter to test the element for continuity.
- Inspect the wiring: Ensure that the wiring connecting the heating element to the control board is secure and not damaged.
- Replace the heating element: If the heating element is faulty, it will need to be replaced.
Resolving Circulation Pump Issues
The circulation pump is responsible for circulating water throughout the dishwasher. If it’s not working properly, the dishes won’t get clean. Here’s how to troubleshoot the circulation pump:
- Check the pump: The circulation pump is located at the bottom of the dishwasher. Inspect it for any debris or blockages that may be preventing it from operating.
- Inspect the wiring: Ensure that the wiring connecting the circulation pump to the control board is secure and not damaged.
- Replace the circulation pump: If the circulation pump is faulty, it will need to be replaced.
Addressing Control Board Problems
The control board is the brain of the dishwasher and controls all its functions. If the control board is malfunctioning, it can prevent the dishwasher from starting. Here are some troubleshooting steps:
- Reset the control board: Sometimes, a simple reset can resolve issues with the control board. Unplug the dishwasher for a few minutes and then plug it back in.
- Check the wiring: Inspect the wiring connecting the control board to the other components of the dishwasher. Ensure that all connections are secure and not damaged.
- Replace the control board: If the control board is faulty, it will need to be replaced by a qualified technician.
Other Potential Issues
In addition to the above issues, there are a few other potential problems that can cause a Bosch dishwasher to flash and not start:
- Door latch: If the door latch is not properly engaged, the dishwasher will not start. Check the latch to ensure that it’s secure.
- Overload: If the dishwasher is overloaded with dishes, it may not be able to start. Remove some dishes and try again.
- Power supply: Make sure the dishwasher is plugged into a working outlet and that the power supply is not interrupted.
Wrapping Up
If you’ve followed the troubleshooting steps outlined in this guide and your Bosch dishwasher is still flashing and not starting, it’s recommended to contact a qualified appliance repair technician. They will be able to diagnose the problem accurately and perform the necessary repairs to get your dishwasher back up and running.
