Bosch is one of the major players in the home appliance industry with a significant share of the dishwasher market. They are usually very reliable, however, unfortunately, sometimes something may go wrong, and you will need to fix the breakdown by repairing a Bosch machine.
The good news is that because these dishwashers are so popular, service, parts and repairs are widely available. These household appliances are actually quite simple, so most of the problems you may encounter often require fairly simple repairs that you can do yourself.
Here are some tips on some of the most common dishwasher problems you may encounter. For more detailed advice on the Bosch dishwasher, we recommend reading our other articles on this topic.
Differences in Dishwasher Models
One of the most common differences between dishwashing machine models is the banal name of the buttons.
For example, Power SCRUB PLUS or REGULAR WASH may be called WASH or ECO depending on the dishwasher model and the country you are in. Another important difference is the presence of a display that can display error codes or lack thereof. In this case, the program indicator button will light up to tell you about the malfunction.
As a reminder, model numbers are usually found at the top or ledge of a door.

Starting a test cycle
Bosch dishwashers have a test mode that can be launched as a troubleshooting measure. The way to start this test process is similar across the entire range of Bosch models, so if your device functions seem to be different from those described below, it is worth trying to experiment, as the process is similar, differing only slightly.
Hold the POWER SCRUB PLUS and REGULAR WASH buttons to start the test mode. Holding the ON / OFF button down can also help. The indicator above them should blink.
Now you can check the status of each program by clicking on the button, or you can start the full testing period.
Press the Power SCRUB PLUS and REGULAR WASH buttons. The electronic device will start, and when the selected mode is over, if you do not have a display, the indicator on your dishwasher model will light up if a malfunction has been detected.
Meaning of fault indicators
CLEAN
Temperature sensor malfunction.If this is the case, then the test cycle will be very short, as the instrument stops testing as soon as it is detected.
RINSE / DRY
Water / tank fill sensor. If this problem occurs, the test cycle will not be completed due to the dishwasher being unable to determine the correct water level by simply filling / draining over and over again.
WASH
Malfunction in heating. Check the heating element.
Display Error Code Values
If your Bosch dishwasher has a display panel, then after completing the test cycle, an error code will be displayed if a malfunction is detected.
Error codes are interpreted as follows:
0 - no errors were found.
1 - Water sensor or filling failure.
2 - Heating malfunction.
4 - Error filling with water. It can also appear as F on the display during a normal cycle.
8 - Faulty temperature sensor.
When troubleshooting a Bosch dishwasher, performing the above test cycle is a good start in diagnosing the problem. The result will give you an idea of where the problem lies, as well as what repairs will be required to fix the problem.
Troubleshooting basic problems
If something goes wrong and doesn't work when starting a wash cycle on your Bosch dishwasher, stay calm. This can be a minor issue, especially if you just installed it.
Power check
Make sure the power cord is plugged in correctly and the switch does not trip.
Airing the hose
After that, check if the hose is not airy, especially if it was not blown before installation, it may have air bubbles inside, which retains water.
To do this, disconnect the water supply hose from the dishwasher and run some water through it before reinstalling the hose.
The wash cycle is interrupted
The Bosch dishwasher does not pick up water if the previous cycle was interrupted. Reset the dishwasher by pressing and holding the “Start” button for at least three seconds.
Depending on the model, you can also click the “Cancel-Reset” button to reset. Select a new cycle and click "Start".
Water supply
Check the water supply hose under the sink. If it was turned off or blocked for any reason, the dishwasher will give an error in the program and will not be able to fill the tank with water, even if the water supply resumes within a few seconds.
Filter hose
Most Bosch dishwashers have a small filter inside the hose to prevent foreign particles from the water supply from entering the dishwasher.
Disconnect the hose and remove the filter inside. Then clean it thoroughly to remove any third-party elements and reinstall it.
Water pressure
Make sure you have enough water pressure to start the dishwasher and pump.
To check, take a 4L container and turn the tap to the maximum to fill it. If you have enough water pressure to start the dishwasher, the container should fill within 30 seconds.
Filler valve problem
Inside the bottom of the dishwasher, on the back of the panel, there is an inlet water fill valve that is powered by electricity.
Unplug the power cord or turn off the power to the device using the machine. Remove the panel by unscrewing the two screws on both sides.
Separate the screws that hold the front door panel inside the dishwasher; pull the door panel down and set it aside.
Close the door to access the water intake valve. The filler valve has two wires that connect it to the block diagram. Check to make sure they are securely fastened.
Also check the valve for damage or leaks. If it is damaged, buy a new one using the model number of the dishwasher and replace it; otherwise, contact your technician to have it done for you.
Thank you so much

At the very end of the process (the dishes are clean!), The remaining (also clean and not soapy) water does not drain - it stands at the level of the pump opening. Checked the filter and pump, as in the video. Everything seems to be normal. The most interesting thing is that this does not happen every time. Approximately 2-3 times for 5 washes.
What could be there?
Good day. An interesting problem, I can't find a similar one anywhere: I open the door after washing, and the tablet lies on the shelf of the upper basket for dishes. Accordingly, the quality of the sink is “just rinsed”. And this has been constant for a week What could it be? Weak water pressure?
Hello! In your case, there may be several reasons:
1. Do not place the tablet with wet hands or in a wet cuvette, it may stick.
2. Perhaps the tablets were not stored correctly, moisture got into them, they hardened and now poorly dissolve or do not dissolve at all.
3. The problem with the dispenser. Perhaps the water supply openings are clogged with detergent or scale.
4. The filter mesh, which is located immediately behind the inlet hose, is clogged.
5. Clogged filler valve.
6. Spray nozzles may become clogged.
It is necessary to check everything consistently for the presence of blockages and, if necessary, clean it.
Good day.
Everything is completely unclear with the machine. I worked for 8 years. Super! But the trouble happened. Water flows in, water is pumped out. And all !!!!! The whole cycle is going on. There are no errors. The tablet remains in place. Even water-soluble protection on it, i.e. water does not splash or heat up. What could be? I ask for advice!
Apparently the washing process does not start for you. Self-draining goes.
When washing, the fuse is knocked out of the system filter! Prior to this incident, the year worked without any problems! I changed the filter, changed the connection point: the story is the same. Fuse blows!
There is a short circuit. You need to consistently check the entire power supply circuit. The filter saves your wiring, it's good that it is.
Good evening.

Help pzhl, thanks in advance.
Hello Bosh SPS40E car. We have such a problem - water is collected, then the tap indicator lights up, then the water is drained and the washing process is over. Thank you in advance.
You are triggered by a water overflow sensor, you need to carry out diagnostics. Alternatively, TENA breaks, but this is less common. Call the master, you cannot fix it yourself.
Hello. The rotating paddle strikes the projections on the bottom of the wash compartment. What can be done?
