Spray Arm Debris Buildup
According to SF Gate, one of the most common reasons that your spray arms arent spinning is debris buildup. Maybe the water wasnt filtered properly before being circulated through the inner workings of your dishwasher, and that could very likely cause a blockage inside your spray arms. If the water isnt able to flow properly through all the small holes of the spray arms, they arent able to spin either.
How to fix The user manual may come in handy here, as youll have to detach the spray arm for a proper inspection and cleaning under running water. It is easily cleaned with a small toothbrush, fingers, or a few toothpicks. Inspect all openings, and use a little dish soap to remove any dirt or debris.
Bosch Dishwashers Control Panel May Be Faulty
If your Bosch dishwashers control panel has no lights, it might be that the control panel has a problem and therefore requires repair or replacement.
If resetting the breaker and turning on power does not turn the lights on, inspect the ribbon wire that connects the control panel to the main board for corrosion, as this might lead to faulty connection.
- Disassemble the control panel and clean the cable terminals of any rust you uncover.
- Check the cable connections to make sure theyre secure even fiddling with the cable a little can help reinstate contact.
If it doesnt work, you may have to get a new control panel installed.

Why My Samsung Dishwasher Wont Turn On
As mentioned earlier, the Samsung dishwasher Turn on when the Dishwasher door switch is defective.
Similarly, another reason for this problem is the faulty control board. A Control board is where you can control your entire dishwasher settings and work.
Any defect on the control panel will affect the dishwasher button, and it will stop you from operating the dishwasher. Here is a list of reasons that could prevent the dishwasher from starting.
What Does The Door Latch Do
The door latch is a mechanical component on your dishwasher that helps to secure the door in place. The door latch usually has a sensor connected to it, which signals the larger control panel that it is safe to start the wash cycle. When the door latch is fully engaged, it will pull the door tightly closed, creating a water-tight seal around the dishwashers door.
When the door latch is not engaged or the sensor is not working correctly, the dishwasher believes the door is left open and unsafe to start the wash cycle. A faulty door latch could be a reason why your Bosch dishwasher is not running.

Lastly, if your dishwasher is taking a really long time to finish a cycle or if it keeps on running, then check to see if theres a problem with the timer motor.
To do this, set your multitester to the x1000 setting and see if you can get a reading of between 2,000 to 3,000 ohms. If you cant, then you need to replace the timer, as shown in this video:

Bosch Dishwasher Doesnt Work Try A Reset
Get to know this often-overlooked Bosch Dishwasher Feature to Avoid this Costly Professional Quick Fix.
For over the five years Ive repaired appliances professionally, there have been occasionsthrough no fault of my own!where Ive had to charge my customer a full diagnostic fee, just to perform a simple Reset for a Bosch dishwasher. Avoid this costly Customer Instruction service call by getting familiar with these dishwashers Reset Feature.
Most modern dishwashers pause the selected wash cycle when the dishwasher door is opened, say to add a dish to the wash load before the dishwasher releases the soap. For many brands and models, the paused wash cycle will automatically start back up where it left off once the door is latched closed. Sometimes machines get old and must be replaced with new ones, other times you move into a new home supplied with Bosch appliances. Some new Bosch owners discover, rather costly so, that many Bosch dishwashers models do not automatically start back up or un-pause when the door is shut.
The common complaint concerning this Bosch dishwasher problem is: the power button is red, but the dishwasher doesnt do anything. I turned the machine off and on, but that didnt fix it. I think the pump is broken. Before going for a replacement pump or motor, find out if a wash cycle was simply interrupted or paused.
The key dance is usually indicated by symbols on the machine control panel as in this example here:
Bosch Dishwasher Not Working/starting/turning On
We depend upon our dishwashers on a daily basis. Most of us probably cant 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.

Bosch Dishwasher Not Working
When youre 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.
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.
How To Reset A Bosch Dishwasher
If you own a modern model of Bosch dishwashers, here’s how to reset it:
For older models, you would usually need to press two buttons to reboot the appliance. You can try holding the Regular Wash and Rinse & Hold buttons simultaneously for about 3 to 5 seconds to reset it.
If this method of rebooting doesn’t work, don’t give up just yet. You can perform a hard reset. Here’s how it’s done.
That’s it! Hopefully, either of these two methods works out for you so your Bosch dishwasher will start working properly once again.

It Might Be A Defective Main Control Board
Your Bosch dishwashers main control board manages every function of the appliance, including draining, drying, and washing. As such, the control board also supplies electricity to almost every electrical part of your dishwasher.
A defective control board may result in it not sending the right voltage to the various components of your dishwasher so it doesnt start. You will again need to use a multimeter to check if power is getting to the control board or not.
If the control board does get power from the plug, but your dishwasher still wont start, it could be a problem with the control board, or it could be something else. So, you might want to first check for a blown-out thermal fuse, door switch, and other components in this section before ordering a replacement control board.
If it is really the control board thats the problem, then you should replace it. How do you do that?
1. You will need to open the dishwasher and take out both the outer and inner door panels. These panels will come off if you take out the screws that secure them in place.
2. Once the panels are taken out, you have access to the control panel and the main control board. Making sure that you take note of the wires and where they go, disconnect the wires from the control board.
3. Release the old control board using a flathead screwdriver and take it out. Replace it with the new control board by snapping the new one into place.

Error Code E0: Heater Relay Fault Or Heating Issue
The E02 error code indicates that the heater relay on the control board has a fault. With some models, the error can be caused by a faulty temperature sensor or thermistor.
If you do not want to pay for a Bosch technician, you could replace the temperature sensor or thermistor to see if it resolves the error code. Replacing the control board is also an option.
Dirty Filters And/or Pump
If your filters and/or pump arent cleaned regularly , they may stop working properly. This could ultimately cause a drop in water pressure, which then affects the entire dishwasher system. If the water pressure drops, your spray arms may not be able to turn.
Another telling sign that your filters need cleaning, is if your dishwasher starts smelling.
How to fix If you havent cleaned your filters and/or pump before, consult your manual for directions on how to do so. Usually youll have to detach the filter and rinse it under running water. We recommend using a regular dish soap and a brush to loosen any grease and get into all little cracks and crevices.

Spray Path Is Blocked
If your dishwasher works well most of the time, it is likely that a pan/pot handle is just in the way and blocking the spray arm from turning. This happens more often than you may think, especially in smaller dishwashers with a third rack where handles from pots and pans could easily get in the way of the spray path.
How to fix The easiest way to ensure that the spray path isnt blocked, is to push the racks in and push each spray arm manually. If they hit anything, move the offending object out of the way to clear the path. Give it another try, and once it successfully rotates all the way around youre good to go.
How Can I Reset The Control Panel
Sometimes, the issue causing the red light to blink on your Bosch dishwasher is simply an incorrect signal being sent from the door latch sensor to the main control panel. Resetting the main control panel can trick the door latch sensor into working correctly again. To reset a Bosch dishwasher, simply follow the below steps.

Bosch Dishwasher Is Not Getting Power
The Bosch dishwasher wont turn on because the power is off.
Make sure It is Plug-In: If your dishwasher is plugged in and the power cord leading to it isnt damaged, then there is an easy way to check if youve got power going through.
Test a lamp near the plug socket. If youre certain that the problem lies with your Bosch dishwasher or its plugin point, try swapping out plugs . Remember to pull on both ends of an old plug, as sometimes they can wiggle loose without much pressure. Be sure not to touch live wires when changing sockets!
Dishwasher breaker tripped: If the power is on and plugged into a working socket, try flipping your Bosch dishwashers breaker. You may have tripped it by accident or you might have blown a fuse. Test other outlets in your home to be sure that this was an isolated incident before calling for repairs. If there are no electrical problems with any of the other sockets in your house, dont hesitate to call up an electrician!
Check the Thermal Fuse: Bosch dishwashers usually have a thermal fuse located on the bottom of your Bosch dishwasher. A thermal fuse will shut power off if the dishwasher overheats. If the fuse blows, itll prevent the machine from starting. To determine if its defective, use a multimeter to check for continuity when measuring the fuse and replace it with one that has continuity.
