Reasons Why Bosch Dishwasher Won't Start
It doesn't have any power
Before attempting to troubleshoot your Bosch dishwasher, it's always a good idea to check the power plug to see if it's plugged in completely. This may seem rather obvious, but you'll be surprised at how often this is the culprit.
Also, make sure that the dishwasher is turned on. Somebody's dishwashers have control panels with indicator lights that can be a bit hidden, making it hard to determine whether or not the unit is on.
Also, make sure that the circuit breaker fuse for the dishwasher is working. Sometimes you may need to reset the breaker if it's tripped. To reset it, go down to the breaker unit and flip the switch up or down, and then back again.
The door is unlocked
This is probably the second most common reason why a dishwasher won't start the dishwasher, similar to other brands. Bosch units have a latch sensor that prevents the dishwasher from starting when the door isn't completely closed.
This is to prevent water from leaking outside of the dishwasher. If the latch is broken or damaged in any way, the door won't close properly. If the latch or switch is broken beyond repair, it'll need to be replaced.
The child lock is enabled
Most Bosch dishwashers come with a child lock setting to prevent children from operating the dishwasher. Sometimes this button can be pressed accidentally if the control panel under a Bosch dishwasher is not easily visible.
To determine if this is the issue, look at your user's manual and find your symbol for the child safety lock. Next, take a close look at your control panel to see if the symbol is lit. If so, be sure to disable it to start the dishwasher.
Issues with the cycle settings
An incorrect cycle selection will also result in start issues. For example, issues with one of the fuses inside the panel box can cause cycle initiation and completion issues. When this is the issue, you'll often see an error code appear on the dishwasher's control panel, but not always.
Most Bosch dishwashers have about 12 error codes that they'll display to help you shoot start and setting issues. If you need additional assistance, it's always a good idea to check your instructional manual. If you can't seem to troubleshoot the issue, reaching out to a technician may be best.
Inadequate water supply
The unit won't start when the dishwasher doesn't have enough water to initiate the cycle. A few things can cause a water supply issue. Issues with your home's waterline could cause it, the valve could be turned off, or the hose could have a kink in it. Make sure that the water supply to your dishwasher isn't restricted.
If you suspect that this is the issue, check the water valve for the dishwasher and make sure that it's turned on and that the dishwasher is fully connected to the supply house. Also, make sure that there are no bends, kinks, or holes in the hose.
If you like to load the dishwasher to the max, this could be causing starter issues. The sprayer arms are located at the bottom of the unit's tub or right beneath the top rack. However, the dishes may prevent the sprayer from rotating if the bottom rack is loaded to the max.
Often when this happens, the unit will shut off due to the automatic sensor. And when it does, this is your chance to open up the unit and rearranged the dishes--a quick and easy fix.
The control board is malfunctioning
If the control board is faulty, it may not provide sufficient power to initiate the start cycle to the dishwasher. And if this is the case, it'll need to be replaced. A new control board for a Bosch dishwasher can range from $65 to over $250. And some cases, it may be easy to replace the control board yourself.
However, for some models, it may be more difficult, as it'll require you to take off the dishwasher panel and remove multiple wires. If you're uncomfortable with electricity, it's best to have a technician do this for you.
The timer is broken
The timer on the dishwasher is responsible for initiating the start of a new wash cycle. However, if the timer is broken are malfunctioning, this will affect the dishwasher's ability to start. You can typically replace the dishwasher timer yourself within a few minutes. If you depart will cost anywhere from $50 to $75 or more, depending on the model you have.
What is the average life expectancy of a dishwasher?
The average life expectancy of a dishwasher is anywhere from 7 to 10 years. Of course, this will vary by brand and model, as are all dishwashers aren't created equally. And of course, maintenance and frequency of use also play a part in how well a dishwasher will hold up over the years.
The major components that may wear out the fastest include the motor and the pump--and when they go out, it's typically best to replace the entire unit. These components can run anywhere from $400 to over $500, but the part alone.

Bosch dishwashers have a warranty of one year. The warranty includes parts and labor.
How much does it cost to repair a Bosch dishwasher?

When should I replace my Bosch dishwasher?
Sometimes it can be tricky to determine whether or not you should replace a part in the dishwasher or buy a new Bosch dishwasher. Well, here are a few scenarios that'll let you know it's probably time to get a new unit.
The dishes aren't hot after the cycle ends
After the dishwasher goes through the washing cycle and then goes through a rinse and drying cycle. Once the cycle has completed, the dishes are usually hot, and the inside of the unit is typically steamy. This is necessary to sanitize the dishes.
If there is an issue with the heating coil inside the unit, the dishes won't be hot or sanitized. And heating coil replacement can be expensive, and it may not be worth the effort.
It becomes rusted
Rust is one of the biggest tell-tale signs that a dishwasher has run its course. If you sweep the floor of your dishwasher unit with a damp paper towel and notice rust stains on it, chances are it's time for a new unit. This means that water is leaking from inside the unit and may be contaminating your dishes.
There are several reasons that may cause this. However, more often than not, it's simply not worth the repair.
You've repaired it more than twice in a short period
If you find yourself dealing with the repairs on the dishwasher in a short time frame, chances are it's time for a new unit, especially if they're issues with drainage, cycling, or the unit's overall performance. Be sure to keep track of every repair you make. And if the unit is over at 7 to 10 years old, perhaps replacing it is the best option.
