Bosch Dishwasher Wont Turn On

Time To Call A Technician


If youre still unable to reset the dishwasher or resolve an issue, your dishwashers manual should provide reset instructions. Dishwasher manuals for your specific model can be found online.

If the problem persists, its likely because of a control board issue that requires a Bosch technician to diagnose and repair it.

What To Do If Your Bosch Dishwasher Is Leaking

Its always alarming when your Bosch dishwasher starts to leak, but the good news is that its generally pretty easy to find the source of the problem and the solution to fix it. One of the most common areas, when theres a leak with your dishwasher, is the door seals. You will probably see this right away as the water will start to leak out from the front of the dishwasher and directly onto the floor.

To solve this you will need to either repair or replace the seal and potentially think about tightening the door latch with a screwdriver to secure it properly.

Another reason why your Bosch dishwasher might be leaking is that you have used the wrong detergent. Depending on which type of detergent you use, this could result in excessive suds which will essentially push water out from the dishwasher causing leaks and flooding.

Outside of these two factors, other reasons why your Bosch dishwasher might be leaking could be that theres a problem with the drain hose, the circulation pump or the gasket. Any one of these will require a thorough inspection, and potentially a full-on replacement if you are unable to unclog or repair the drain, pump or gasket.

Watch Out For A Blown Thermal Fuse

The thermal fuse keeps your Bosch dishwasher from overheating. A blown fuse will result in a dishwasher that doesnt start.

Use a multimeter to check for continuity. A continuity test will let you know if there is a continuous electrical path within the fuse.

And heres how you do that:

If its really a blown fuse, you will need to replace it.

Check The Control Panel

The control panel could be dead or faulty so there will be no response at all when you try to make it turn on .

Here you should first try to disconnect the control panel connectors and clean off any corrosion/grime.

You then connect them back and check if the machine powers on.

If it doesnt, replace the whole control panel and see.

Check The Wiring Harness

Dishwasher photo and guides: Bosch Dishwasher Wont Start But Has Power

The wiring or cable harness consists of various wires that connect to various parts of the dishwasher. On most models, the wiring harness can be found with the control panel. Excess heat sometimes damages the wiring harness, or wires can melt and attach to the dishwasher.

  • Examine the wiring harness for any of the above issues.
  • Replacing the wiring harness is difficult and should only be attempted by professionals. This is especially true if multiple wires need to be replaced. A mistake will likely be costly and dangerous.
  • Replacing a couple of easily accessible wires is slightly easier, but it is still best repaired by a professional.

Bosch Classixx Dishwasher Not Starting

If your Bosch dishwasher wont start, the most likely causes are listed below. Check these before calling a service technician.

-Door switch: The door switch activates the dishwasher when you close the door and prevents it from running while the door is open. If the switch is defective, the dishwasher may not start.

-Water inlet valve: The water inlet valve opens to allow water to enter the dishwasher. If the valve is defective, the dishwasher wont fill and may not start.

-Thermostat: The thermostat monitors the dishwasher temperature and controls the heating element. If the thermostat is defective, the dishwasher may not heat the water and may not start.

-Control board: The control board controls the dishwasher cycle, timing, and functions. If the control board is defective, the dishwasher wont start or may run through a cycle without stopping.

Check The Door Switch

If the latch is latching correctly, the door switch may have an electrical fault. The door switch allows power to the dishwasher only if the door is properly closed. Sometimes the door switch will come loose, or water can get in and damage it.

  • Disconnect the dishwasher from its power source.
  • On most models, the dishwasher switch can be accessed by unscrewing the control panel. On other models, the dishwasher front panel will need to be removed to access it.
  • If the door switch was not connected, plugging it in should solve the power issue.
  • To check if the door switch is faulty, disconnect it from the dishwasher and use a multimeter to check for continuity. If there is more than one wire connecting it, take note of where each wire goes.
  • If it fails the multimeter test, replace the door switch.

    Check The Water Supply

    If it has power but your Bosch dishwasher wont start or fill with water, there may be a water supply issue.

    The following water supply problems can prevent an immediate start:

    • Supply valve is off: Make sure the valve is turned on so water can flow from your home supply.
    • Kinked water inlet hose: If the water inlet hose is kinked, it can block water flow from your home supply. Gently straighten any kinks, disconnecting the hose, if necessary, to restore flow.
    • Faulty water inlet valve: This valve is attached to the water inlet hose connection, opening and closing to allow for water flow from your home supply. If the valve is faulty or stuck closed, water may not flow to the dishwasher, preventing it from starting. In this case, the valve cant be repaired and must be professionally replaced.

    No Power To Washing Machine


    A Bosch washing machine wont turn on or perform any other function without consistent power. Be sure to check all power sources to make sure theyre functioning properly.

    Heres how to assess for power problems when your Bosch washer wont start:

    • Check the power cord: Make sure its completely plugged into a functioning outlet.
    • Avoid extension cords: These cords cant safely transmit the voltage a washer requires, resulting in surges that interrupt power.
    • Look for tripped breakers: Check your homes circuit breaker box and reset any tripped breakers.

    Examine Junction Box Wiring

    If your dishwashers power cord doesnt plug into an electrical outlet under the sink, then the power supply is hardwired into the junction box. Check the power cord connections in the junction box. The above video shows how to follow these steps to check junction box wiring.

    Note: If youre not completely confident that you can safely complete this troubleshooting procedure, then its time to schedule a service technician to diagnose and repair your dishwasher.

    • Shut off the house circuit breaker for the dishwasher to disconnect electrical poweryou dont want electricity flowing to the junction box.
    • Remove the dishwashers bottom front access panel and toe panel. On most dishwashers, youll need to take out the mounting screws from each side and then pull off the panels.
    • Remove the screw from the junction box cover and pull off the cover.
    • Check the black wire connection and the white wire connection.

    Reconnect any loose or disconnected wires. Reinstall the junction box cover and then reinstall the bottom front access panel and toe panel. Restore electrical power to the dishwasher and see if the dishwasher works.

    Water Not Filling Up Dishwasher

    The fourth common problem associated with Bosch dishwashers is that water does not fill up the dishwasher.

    This is a problem since it will not allow the dishwasher to properly clean your dishes, which is unsanitary.

    It is important to fix this problem right away.

    Like many of the other problems on this list, water not filling up the dishwasher is caused by a faulty water inlet valve.

    If the valve is defective, it can cause it to close early, which prevents water from fully filling up the dishwasher during the cycle.

    To fix this problem, you can replace the water inlet valve. You do this by removing the old valve, which is accessed by the lower access panels.

    You will need to detach a wire harness, disconnect the water line, and remove the brass elbow.

    Then, remove the old water inlet valve and replace it with the new one. Reassemble your dishwasher and test to make sure it is fixed.

    You may also want to test the solenoids of the dishwasher. The solenoids are magnets that allow the water inlet valve to open and close.

    You will use a multimeter to see if there is an issue with the solenoids.

    Bosch Dishwasher Stuck On Autocause And Solutions

    As great as the Auto wash cycle is, there might be a time when it fails to do anything. You could activate the Auto cycle at night and find in the morning that it hasnt done a thing.

    Oftentimes, there can be problems with the dishwashers electronic control board. This component is responsible for choosing which wash cycles to run and for how long. After running hundreds of wash cycles, the control board may experience minor technical problems that can be resolved by hard resetting the machine.

    Bosch Dishwashers Timer May Be Faulty

    An electronic control and a timer powers your Bosch dishwasher by determining the amount of electricity used by each component. Additionally, they regulate the heating circuit, the water inflow valve and the drain pump.

    If the electronic control and timer has problems, the unit will still power up, but it wont perform as expected. The unit may run a wash cycle, but its unlikely that the control panel will light up.

    To troubleshoot this issue:

    Use the Klein Tools MM600 Multimeter to test the resistance. If the resistance doesnt fall between 2,000 and 3,500 ohms, the electronic control and timer arent working properly.

    In this case, youll need to replace the current electronic control and/or the timer with new ones.

    Check The Dishwasher Power Cord

    Some dishwashers have a power cord that plugs into an electrical outlet under the sink, while other dishwasher power cords are wired directly from the wall to the wires in the dishwashers junction box. If your dishwasher power cord plugs into an electrical outlet, make sure the power cord is plugged in.

    If the power cord is plugged in, its possible the electrical outlet doesnt work. Check the electrical outlet for power by plugging in a small lamp. If it doesnt light up, have an electrician repair the bad outlet.

    Heres a helpful troubleshooting video that shows this step and additional troubleshooting steps to take when your dishwasher has now power.

    Could It Be The Main Control Module

    A damaged electronic control board is another likely cause especially if power is coming into your control but the appliance wont do anything else.

    But you should not be too quick to order a new control- visually inspect it first for issues like frayed wires, burnt parts, and improper/loose connections.

    To add, it is fairly common to find connectors that have come loose often due to inadequate fastening.

    The thing is, once you used the unit for a while, these connections will start to become loose because of the vibrations made during normal operations.

    The can ultimately cut power to the control panel.

    So check for all these probable problems and try to repair .

    If you have not succeeded, trying a new control is your remaining option.

    Again find a compatible control board and go ahead with the replacement.

    Keep in mind that vendors will ask for the part number and not your Bosch dishwasher model number .

    Bosch Dishwasher Display Not Working When The Door Is Closed

    The dishwasher wont start operating if the door doesnt close well enough to activate the latch switches. So if your Bosch dishwashers display wont turn on or work even when the door is closed, its likely the latch has a problem.

    More often than not, you might be dealing with damaged door switches, which youll have to replace to get the unit to work properly.

    • Remove the inner door panel and search for the door latch assembly near the top of the door.
    • Insert the latch into the assembly, as doing so is only way to know if the switches are active.
    • Set the multimeter to Rx1. Probe the switchs terminals and check the voltage. Check for a reading of zero or very near to zero, just as you would with the fuse

    If you dont get a zero reading or a reading close to zero, get a new door lock kit compatible with Bosch dishwasher.
