Bosch Dishwasher Error Codes – Learning Yours

Bosch Dishwasher

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 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 these are specific to the SMH/SH series, as well as Logixx/Exxcel machines.

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.

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 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.

Error codes E09, E10 and E11 are a water heating problem, an issue with the heating element and a faulty temperature gauge respectively. 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!

Those Awkward Middle Codes

For the sake of simplicity, we can group 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 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. 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!

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. 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 Error Messages!

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.

Overall, these are all of the different standard Bosch error codes that your dishwasher can showcase. As you can see, there’s a lot of them. In many respects, this is a good thing.
