Bosch Dishwasher Starts Then Stops

If your Bosch dishwasher is exhibiting the frustrating behavior of starting and then stopping abruptly, it can be a perplexing issue to diagnose. However, with a systematic approach and some basic troubleshooting, you can often identify and potentially resolve the problem without the need for professional assistance. Here’s a step-by-step guide to help you get your dishwasher back in working order:

1. Check for Power Supply Issues

a. Verify Electrical Connection


Inspect your home’s circuit breaker or fuse box. It’s possible that the dishwasher’s circuit has tripped or a fuse has blown. If you find a tripped breaker or a blown fuse, reset it or replace it accordingly.

2. Examine the Door Latch

a. Door Latch Alignment

A common reason for a Bosch dishwasher to stop mid-cycle is an improperly aligned door latch. Ensure that the dishwasher door is securely closed and that the latch is properly engaged. Misalignment can trigger the dishwasher to halt as a safety precaution.

b. Door Gasket Inspection

Check the door gasket for any damage or debris that may prevent the door from sealing properly. A compromised seal can cause water leakage and trigger the dishwasher to stop.

3. Inspect the Water Supply

a. Water Inlet Valve

If the dishwasher doesn’t receive an adequate water supply, it may start but then stop. Make sure the water inlet valve, usually located at the bottom of the dishwasher, is free from obstructions and functioning correctly.

b. Water Pressure

Inadequate water pressure can also lead to start-and-stop issues. Ensure that the water pressure in your home is sufficient for the dishwasher’s requirements. Check for any clogs or kinks in the water supply line.

4. Check for Blocked Spray Arms

a. Remove Dishware

Open the dishwasher and remove all dishes, racks, and utensil holders to access the spray arms.

b. Clean Spray Arms

Inspect the spray arms for debris, such as food particles or mineral deposits, which can block the water flow. Clean any obstructions you find.

5. Evaluate the Float Switch

a. Locate the Float Switch

The float switch is a safety device in the bottom of the dishwasher that monitors the water level. If it detects an overfill situation, it will stop the dishwasher. Check the float switch for any obstructions or damage.

b. Reset the Float Switch

Gently lift the float assembly and ensure it moves freely. If it was stuck, this might have caused the issue. After cleaning and resetting it, run a test cycle.

6. Run a Diagnostic Test

a. Bosch Diagnostic Mode

Many Bosch dishwashers have a diagnostic mode that can help identify specific problems. Refer to your dishwasher’s user manual for instructions on how to enter the diagnostic mode and interpret error codes.

7. Seek Professional Assistance

If none of the above steps resolve the issue and your Bosch dishwasher still starts and stops intermittently, it’s time to contact a professional appliance technician. There could be an underlying electrical, electronic, or mechanical problem that requires expert diagnosis and repair.

8. Inspect the Control Panel

a. Control Lock

Sometimes, the control panel may be locked, preventing the dishwasher from functioning properly. Check if there’s a control lock feature on your Bosch dishwasher, and if it’s activated, deactivate it according to the user manual instructions.

b. Control Panel Buttons

Examine the control panel buttons and their responsiveness. If any buttons are stuck or not responding, it can disrupt the dishwasher’s operation. Clean the control panel and ensure all buttons are functioning correctly.

9. Clean the Filters and Drain Pump

a. Remove Filter Components

Bosch dishwashers typically have multiple filters to trap food particles and debris. These filters can become clogged over time, affecting water flow and causing interruptions in the cycle. Remove the filter components and clean them thoroughly.

b. Check the Drain Pump

A blocked or malfunctioning drain pump can lead to water not draining properly, causing the dishwasher to stop. Inspect the drain pump for obstructions or damage. Clear any debris and ensure the impeller spins freely.

10. Consider Water Quality

a. Hard Water Issues

If you live in an area with hard water, mineral deposits can accumulate inside the dishwasher’s components, including the heating element and spray arms. Over time, this can lead to performance issues. Use a dishwasher cleaner specifically designed to remove mineral buildup periodically.

11. Update Firmware (if applicable)

For some Bosch dishwashers with advanced electronic controls, firmware updates may be available to address software-related issues. Check the manufacturer’s website or contact Bosch customer support to determine if there are any available updates for your dishwasher’s control system.

12. Monitor Error Codes

If your Bosch dishwasher displays error codes on the control panel, refer to the user manual to decipher their meaning. Error codes can provide valuable information about the specific issue affecting your dishwasher.

13. Run a Short Cycle Test

To further diagnose the problem, run a short cycle with no dishes in the dishwasher. This can help determine if the issue is related to a particular component or if it occurs consistently across all cycles.

14. Consider Professional Repair

If you’ve exhausted all the above troubleshooting steps and your Bosch dishwasher still starts and stops, it’s advisable to contact a certified Bosch appliance technician or a qualified repair service. They have the tools and expertise to diagnose and repair complex issues with your dishwasher, which may involve replacing faulty components or conducting advanced diagnostics.
