Bosch Dishwasher Not Starting? 7 Fixes to Try NOW!
If your Bosch dishwasher is refusing to start, it can be a frustrating experience. Often, the reason why won’t my Bosch dishwasher start is a simple fix you can handle yourself. This guide walks you through the most common causes and provides easy-to-follow solutions to get your dishwasher running again.
1. Check the Power Supply
The first step is to ensure your dishwasher is actually receiving power. A surprising number of "not starting" issues stem from a simple power problem.
Is the Dishwasher Plugged In?
This might seem obvious, but double-check that the power cord is securely plugged into the electrical outlet. It’s easy for cords to be accidentally bumped or loosened.
Check the Circuit Breaker
Locate the circuit breaker that controls your dishwasher. If the breaker has tripped, flip it to the "off" position and then back to the "on" position. If the breaker immediately trips again, there’s a potential electrical problem that requires a qualified electrician.
Test the Outlet
Use a different appliance (like a lamp or phone charger) to test the outlet. If the other appliance doesn’t work either, the outlet itself may be faulty, and you’ll need to contact an electrician.
2. Examine the Door Latch
Bosch dishwashers have safety features designed to prevent operation if the door isn’t properly closed and latched.
Ensure the Door is Fully Closed
Make sure the dishwasher door is firmly closed and latched. Sometimes, an object inside the dishwasher can prevent the door from closing completely.
Inspect the Door Latch Mechanism
Visually inspect the door latch for any signs of damage or obstruction. Look for broken parts, debris, or anything that might be preventing the latch from engaging. A faulty latch switch will prevent the dishwasher from starting.
3. Verify the Water Supply
Dishwashers need water to operate. If the water supply is cut off, the dishwasher won’t start.
Check the Water Shut-Off Valve
Locate the water shut-off valve for your dishwasher (usually under the sink). Ensure the valve is fully open.
Inspect the Water Inlet Hose
Make sure the water inlet hose isn’t kinked or blocked. Kinks can restrict water flow and prevent the dishwasher from filling. Straighten any kinks you find.
4. Address Control Lock/Child Lock Issues
Many Bosch dishwashers have a control lock or child lock feature that can disable the control panel. If this feature is activated, the dishwasher won’t respond to button presses.
Deactivate the Control Lock
Consult your dishwasher’s manual for instructions on how to deactivate the control lock. Typically, this involves pressing and holding a specific button or combination of buttons for a few seconds.
5. Resolve Error Codes
Modern Bosch dishwashers often display error codes that can provide valuable clues about the problem.
Identify the Error Code
If your dishwasher displays an error code, write it down.
Consult the User Manual
Look up the error code in your dishwasher’s user manual. The manual will explain the meaning of the code and suggest troubleshooting steps.
Common Error Codes and Potential Causes
| Error Code Example | Possible Cause | Solution |
|---|---|---|
| E15 | Water Leak | Check for leaks inside the dishwasher and around the water inlet valve. |
| E24 | Drain Problem | Check the drain hose for blockages and ensure the drain pump is functioning. |
| E22 | Filter is Blocked | Clean the dishwasher filter thoroughly. |
6. Check the Float Switch
The float switch prevents overfilling. If it’s stuck in the "up" position, the dishwasher may think it’s already full and won’t start.
Locate the Float Switch
The float switch is usually located at the bottom of the dishwasher tub, near the front. It’s typically a small, cylindrical plastic piece.
Check for Obstructions
Ensure the float switch can move freely up and down. Remove any debris or food particles that might be blocking it.
7. Reset the Dishwasher
Sometimes, a simple reset can resolve minor glitches.
Perform a Hard Reset
Unplug the dishwasher from the power outlet for 5-10 minutes. Then, plug it back in. This will reset the dishwasher’s electronic controls.
Consult the User Manual for Specific Reset Instructions
Some Bosch dishwasher models have specific reset procedures. Refer to your user manual for detailed instructions.
