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.

Improper loading

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.

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.
