Your guide to all Bosch dishwasher error codes
Bosch dishwashers are complex machines, you know? They’re technological marvels of course, but outside of that they serve a particular purpose, and that is to make our lives easier. Your dishwasher has been designed to inform you if something is going wrong with it, and has a set of Bosch error codes which need to be memorised and learnt so that you can respond quickly to a problem.
We’re going to be taking a look at the various Bosch error messages you can get so that you’re ready to make plans promptly.
The First Bosch Error Codes
To begin with, we’re going to be taking a look at the first handful of error codes for Bosch dishwashers. It’s important to remember that some of these are specific to the SMH/SH series, as well as Logixx/Exxcel machines.
Error Code: E01 – E05
Bosch error codes E01 – E05 all serve to inform you that your dishwasher has experienced an issue with its power module. Typically, this is indicative of a failure! However, there’s an unfortunate design in this type of dishwasher which causes the system to lock up and prevent you from replacing the module yourself, so you’ll need to contact a professional. We speculate that this is the case to avoid damage to the system and also to keep you safe from harm.
E01 error code typically means a heat pump motor circuit fault.
E02 and E03 error codes indicate a main control board relay fault.
E05 error code suggests a fault related to the wash arm diverter circuit in the main control board of your dishwasher.
Here are some general steps you can take to address the issues:
- Turn off the dishwasher by unplugging it or switching off the circuit breaker.
- Wait for about 30 seconds to allow the electronics to reset.
- Turn the dishwasher back on.
Error Code: E06, E07, E08
Bosch fault code E06 is a problem with the door mechanism, which means that the system that locks the door and begins the washing cycle is damaged or obstructed, so you should check for obvious errors and try again.
E07 means that your Bosch dishwasher isn’t drying dishes anymore, and E08 is indicative of the water not rising above the heating element, which is often the component at fault.
You can try to reset the dishwasher and if the issue persists despite these efforts, it might require professional assistance.
Error Code: E09, E10 and E11
Error codes E09, E10 and E11 are a water heating problem, an issue with the heating element and a faulty temperature gauge respectively.
Issues related to water heating problems in a dishwasher can indeed be complex and often involve electrical components and potentially the heating element itself.
If you’re experiencing difficulties with water heating in your dishwasher, especially if the problem persists after basic troubleshooting, it’s a good idea to seek the assistance of a professional appliance repair technician.
Error Code: E13 and E14
There isn’t a fault code listed as E12, so we move onto E13, which is the water temperature rising past 75 degrees, and gets fixed by lowering the heat levels of the dishwasher.
E14 is the reed switch sensor fault – we get this one in quite a lot at Just Fixed!
Reed switches are magnetic switches that are commonly used in dishwashers for sensing the opening and closing of doors or other moving parts.
Replacing a reed switch in an appliance typically involves technical skills.
While basic troubleshooting and maintenance tasks can be performed by homeowners, when it comes to more complex components like reed switches or other internal sensors, it’s usually best to seek professional assistance.
Those Awkward Middle Codes
Error Code: E15 – E18
For the sake of simplicity, we can group Bosch fault codes E15 – E18, because they’re all to do with various errors which can occur with the water.
There’s usually an issue with the supply or the sensor which dispenses the water so you’ll need to take it to a professional.
Error Code: E20
Error code E20 is where there’s an electrical short or even a break! This type of problem can be a difficult one, and it’s important to get some help if you’re looking to try and work around it.
Error Code: E21
E21 is a blocked circulating pump, and there’s no E22. As a numbering system, it doesn’t make a whole lot of sense sometimes!
If you suspect that the circulating pump in your dishwasher is blocked, it’s important to address the issue promptly. Turn off the dishwasher by unplugging it or switching off the circuit breaker to ensure safety during the troubleshooting process.
Inspect the area around the circulating pump for any visible debris, food particles, or foreign objects that might be blocking the pump. All dishwashers have filters – check and clean these components, as debris in the filters can affect water circulation. After checking for and addressing any blockages, run a short test cycle to see if the issue persists.
If the problem persists after attempting these steps, it’s advisable to consult with a professional appliance repair technician.
Error Code: E23
E23 is next on the list, and it’s similar to E20, only there’s a problem with the electrical components of the drain pump.
Loose or damaged electrical connections can disrupt the power supply to the drain pump. Working with electrical components can be hazardous, and it’s recommended to seek professional assistance. A qualified appliance technician can diagnose the specific problem, replace faulty parts, and ensure the dishwasher functions properly.
Error Code: E24, E25
Error code E24 is a simple enough problem; the dishwasher isn’t draining correctly. If you’re wondering just how many of these codes exist, don’t worry because we’re nearly at the end.
E24 is unique because it shares the same problem with E25, only they have two different causes! While both codes point to the dishwasher not draining in the way it should, E25 can also be indicative of a blocked drain pump.
The Last Few Bosch Error Messages!
Error Code: E26, E28
Bringing our general list of Bosch error messages to an end, E26 is considered to be an issue with the regulator or the water switch. You can check the latter for yourself, and it’s not too difficult to replace.
Finally, we’ve got E28. This code represents a fault which has connects with a part of your machine known as the turbidity sensor. Now, if you don’t understand what that is, don’t worry! You can quickly identify this problem by looking at your dishes and seeing if they’re not cleaning properly.
