Bosch Dishwasher Not Working/Starting/Turning On

We depend upon our dishwashers on a daily basis. Most of us probably can’t remember the last time we washed a load by hand. If your Bosch dishwasher is not working, getting it fixed is a priority.

Performing a soft reset is the fastest way to get your Bosch dishwasher working again. Close the door tightly and press the start button for 5 seconds. If you hear a sound like a dishwasher pump running, it was probably stuck in the middle of a cycle.

If you must do any work on your dishwasher, you should always keep safety foremost in mind. Working on electrical appliances, even if it is only 110 V can produce a shock that could kill you.

If you are not comfortable working with electrical parts, it is best to call a repairman. Make sure that you choose a repairman that is certified to work on Bosch equipment.

When you’re Bosch dishwasher is not working, check to ensure that there is power to it. If not, restoring the power will often restore the operation of the dishwasher.

A tripped breaker will keep a Bosch dishwasher from working. None of the lights will operate and it will not chime or start. Restore the breaker by turning it to the off position and back on again. You can also check the receptacle and power cord.

A dishwasher uses a lot of power. That is why it is important to make sure that you are not overloading the circuit.

In most cases, your dishwasher should be operating on its own circuit with at least a 20 amp breaker. A 15 amp breaker may struggle to provide enough power and if you are running other kitchen appliances on the same circuit, the breaker may trip continually.

If you have a problem with the breaker tripping, you should unplug the dishwasher and any other appliances on the circuit. Plug them in one by one and try operating them. If one of the appliances continually trips a breaker, it should be repaired.

If the breaker trips without anything plugged into the circuit, the problem is likely either with the wiring or with the breaker itself. Contact an electrician to have this problem looked into right away. It could be a fire hazard.

Press and hold the start button for five seconds while the door is closed. This should start the dishwasher automatically. If you hear the motor operating or if it is trying to drain, the dishwasher is working but it may be stuck in the middle of a cycle.

The control board for the microwave has a memory. If the power was interrupted or if anything stopped the dishwasher from fully completing its cycle, it will try to start where it left off.

At times, this may confuse the control board and the dishwasher may not operate properly. When that happens, you can reset the dishwasher and start fresh.

Check the manual that came with your Bosch dishwasher for instructions on how to reset. There may be a button, such as a cancel button, that you would hold in for a few seconds. It may also be a combination of buttons.

A full reset of the dishwasher can also be completed by turning off the power for at least 60 seconds. You can unplug the dishwasher if you have access to the receptacle or you can turn the power off at the breaker.

If the dishwasher is still not working, try resetting the dishwasher and leaving it unplugged or the breaker off for hours, perhaps even overnight. This may help to restore the operation of your Bosch dishwasher.

Bosch Dishwasher Not Starting/Turning On

When a dishwasher won’t turn on, it can be a frustrating problem. The solution is often as easy as pushing a few buttons.

If you have a faulty door latch or door sensor, your Bosch dishwasher will not start or turn on. You may have power to the control board and the lights may be on, but the dishwasher will not operate because it thinks the door is open.

You can test both the door latch and a door sensor by using a multi-meter and checking continuity. In order to do this, you must first turn off the power to the dishwasher and remove those items. If there is a problem, those items can easily be replaced.

You may have noticed that opening the door in the middle of a cycle will stop the Bosch dishwasher from operating. This is by design. The door sensor and latch work together to let the control board know that the door is closed.

If the door latch is not operating properly, the door may open in the middle of a cycle. The pressure from the inside of the dishwasher is enough to open it.

The door may not open fully but it may open enough that it stops the dishwasher and it may not turn on again until you push it closed.

Something similar is also true with the door sensor. If the door sensor is not indicating that the door is closed, it will not turn on or start.

At times, an interrupted cycle may also keep your Bosch dishwasher from starting or turning on. You can cancel the cycle by holding the cancel button for five seconds.

A soft restart of the dishwasher may also be necessary. Turn off the power by unplugging the dishwasher or turning off the circuit breaker and leave the power off for 60 seconds. Restore the power and it may allow your dishwasher to start working again.

There is a thermal fuse inside of your Bosch dishwasher that will automatically stop the dishwasher from operating if it gets too hot. If the thermal fuse is going bad or has failed, it will not allow your dishwasher to start.

Another issue could be the control panel. It is impossible to test the control panel but you can do a visual inspection. Turn off the dishwasher and remove the control panel and ribbon cable. Inspect it with a magnifying glass and if any burnt areas or cracks are seen, replace the control panel.

Finally, you may have an issue with the motor. If it seems like the dishwasher wants to start but is not operating, the fault could be with the motor.

Try to clean the bottom of the dishwasher and remove anything that may be hampering the motor from operating. You can also remove the motor and check continuity using a multi-meter. Your Bosch dishwasher motor can be replaced but it cannot be repaired.

Bosch Dishwasher Beeps But Doesn’t Turn On

A Bosch dishwasher that beeps but doesn’t turn on is both good news and bad news. The good news is, the dishwasher is getting power. The bad news is, something is wrong.

Your Bosch dishwasher is experiencing an error that needs to be corrected. The likely culprit is the door latch or sensor. They signal the dishwasher that the door is open and when you try to run it, it will be to let you know there is a problem.

The first thing to check when your Bosch dishwasher is experiencing problems is if there is an error code. You can reference the error code in your dishwasher documentation and user’s manual.

If there is not an error code, there is still likely an error that is causing the dishwasher to beep. One of the most common reasons why this happens is because the door latch or sensor has failed.

Your Bosch dishwasher will automatically shut off when you open the door so if the sensor is not operating properly, it will think that the door is open. You can check the sensor by using a multimeter and testing for continuity. Replace if necessary.

If the door latch is loose, it might also allow the dishwasher door to come open far enough that it triggers the sensor. Try pulling on the door without using the latch and see if it opens.

At times, a beeping dishwasher may signify that it is not draining properly. This can be associated with the following issues:

Drainpipe

Examine the drainpipe and make sure that there are not any kinks, bends, or that it is not crushed. You should also make sure that there are no clogs in the dishwasher drain hose, especially where it turns a corner or attaches to the garbage disposal.

Garbage Disposal

If the garbage disposal is clogged, it will not allow the dishwasher to drain. This issue is usually easy to identify because the sink will fill with water.

Filter

There is a filter in your Bosch dishwasher that keeps large particles from entering the drain hose. Make sure that the filter is cleaned on a regular basis.

Pump

One other issue that could keep the dishwasher from operating and cause beeping is if the pump is not working. You can check the pump with a multi-meter for continuity.

If you recently had a power outage or if the dishwasher door was opened in the middle of a cycle, the dishwasher may be trying to finish the cycle.

You can reset the dishwasher by unplugging it or turning it off at the breaker panel. After waiting at least 60 seconds, restore power and it may start working again.

Bosch Dishwasher Blinking Red Light But Will Not Start

Most people automatically assume that a red flashing light is bad news. It may be bad news with your Bosch dishwasher, but the fix is typically easy.

A flashing red light on your Bosch dishwasher indicates that the door is not latched properly. The door must remain latched for the cycle to continue. Make sure that the door is closed and if it is latched, test the door sensor.

A blinking red light on your Bosch dishwasher means that there is a problem. A solid red light, however, means that it is running. This can be an issue, especially on quiet models.

Some Bosch dishwasher models are so quiet that you may not even realize they are running. When you see the red light you might assume that something is wrong but it might actually be running in the background. You can check by opening the door for a moment.

Holding down the start button for 5 seconds might also reset the machine and start it working again. This is a simple way to reset most Bosch dishwashers.

You can also reset your Bosch dishwasher by using the power. Disconnect the dishwasher by unplugging it or turning off the breaker in the breaker panel. Wait at least 60 seconds before starting again. In some cases, you may want to try leaving it turned off overnight.

Bosch Dishwasher Hums But Won’t Start

Are you hearing a humming noise from your Bosch dishwasher and it won’t start? We have a solution for you below.

The pump motor in your dishwasher is likely seized if you are hearing a humming noise. This may require that the pump be replaced or it could be too much debris in the dishwasher that is blocking the drain pump.

In many cases, a bad drain motor will make noise before it actually goes bad. This could be a humming, a high pitch squealing, or another unusual sound.

If you think that your dishwasher is making an unusual sound and suddenly, it is humming or not working, it is likely a problem with the motor. This may not be as bad as it sounds.

In some cases, the motor may start operating again but it might just be a problem with the seals drying and sticking. Dishwashers were made to run on a regular basis and if you haven’t run your dishwasher in a week or longer, the pump seals may need to be primed.

In order to prime the pump seals, manually drain the dishwasher and then add a quart of hot water with a cup of vinegar. Pour it directly into the sump area and allow it to sit for half an hour. You can then run an empty load.

One other part of the dishwasher that could make a humming noise is the water valve. If there is a problem with the water valve, the dishwasher may not operate.

Bosch Dishwasher Won’t Delay Start

Delay start is a very convenient option offered on most Bosch dishwashers. It can be frustrating when it doesn’t operate properly.

A problem with the control board can cause the delay start to stop operating. You can’t test a control board but you can remove it along with the power ribbon and visually inspect it. If you see any burned areas or cracks, the control board should be changed.

It is also important for the water to heat in order for delay start to work. A cycle will not complete without hot water, so if the heating element is not working, it might stop the dishwasher from starting.

If the system is clogged and not draining, it might also stop the delay start from operating properly. Check the drain hose, garbage disposal, and drain valve for issues.

One other issue that could lead to the dishwasher not operating under a delay start is the timer. Timers in dishwashers and many other home appliances are often replaced unnecessarily. Check continuity with a multi-meter before replacing it.

Bosch Dishwasher Keeps Stopping And Starting

Is your dishwasher running for a little while and then stopping? This can be a frustrating experience.

If the dishwasher door is not closed completely it will stop running in the middle of a cycle. Push the door shut until it latches in place. If it continues to be a problem, you can check the door sensor using a multi-meter.

Aside from the dishwasher door issue, it may also be a power problem. Intermittent power may sometimes be an issue when a receptacle or breaker is going bad. You might also have the problem if an in-line fuse is failing.

A problem with the thermal fuse can also cause the dishwasher to stop and start frequently. When the thermal fuse fails, the dishwasher will not run but while it is failing, it may intermittently work.

Bosch Dishwasher Start Button Not Working

The start button is the most commonly used button on your Bosch dishwasher. To have it stop operating is a real inconvenience.

If the touchpad and control panel are not operating properly, it may cause some of the buttons to be unresponsive. You might have to replace the control panel, which is likely attached to the touchpad. Cleaning the touchpad may sometimes work as well.

If the control panel does not solve the problem, it may be an issue with the main control board in the dishwasher. The control board is like the computer that runs the dishwasher and if it is failing, problems are likely to occur.

If your Bosch dishwasher is not working, starting, or turning on, push the door closed completely and hold it shut. Press the start button for five seconds to reset the dishwasher. Try running an empty load to see if it works.
