Anytime one of our pieces of technology gives us an error code it can be pretty annoying and frustrating. These error codes can be especially frustrating if they show up on our appliances, like your Bosch dishwasher for instance. If you are having the error codes E15, E22, E01, E09 show up on your Bosch dishwasher then check out this guide to help you fix them.

Bosch dishwashers are very reliable, but also very affordable appliances. They can be purchased at any store that sells appliances, such as Lowes, Home Depot, and Best Buy. If you are getting error codes on your dishwasher it does not necessarily mean that your appliance is broken. The Bosch dishwasher error codes E22, E15, E09, and E01, in particular, have very simple fixes that really anyone can do. Now they will require moving your dishwasher (unless you can easily get to the power cord), so that might be the only thing you’ll need help with. Let’s go over them:

Bosch Dishwasher Error Code E22

You might be curious as to what this error code actually means. When you see E22 pop up it means there is still water in the sump pump. This typically means that there is a blockage of some sort either in the filter or even in the pump itself. While that may sound or complicated, or bad, it really is not a big deal to fix. The first step you will need to try is to clear out the filter. Follow these steps to do that:

  1. Before you do anything make sure that your dishwasher is off
  2. Pull out, and remove, the bottom tray from the dishwasher
  3. On that bottom tray, you will find the filter with an arrow showing that it will be in the locked position
  4. Twist the filter to unlock it and completely remove it from the actual base of your machine
  5. Now remove that bottom tray and clean it very with water or whatever you have on hand
  6. If you notice that your filter looks totally filthy then you need to replace it instead of cleaning it
    1. Best way to find a filter is to know the model of your dishwasher and go to the store where you purchased your appliance. That store will usually carry the filters so you can buy one and install it
    2. OR, you can also get one from Amazon, just know that it will take a few days to ship
  7. After you either clean or replace the filter, install it back in and put the bottom tray back onto the machine and power it up

If your dishwasher still shows error code E22, follow these steps to clear out your sump pump:

  1. Remove the filter and tray and then remove the pump located at the bottom of your appliance (this might take some teamwork depending on how tight the pump is attached
  2. Clear out the pump with water or whatever you have on hand
  3. Place the pump back where it belongs after you ensure that it is cleared of any debris causing it to clog up

Bosch Dishwasher Error Code E1

This error code means that your appliance is having problems with the water pressure in your appliance. While this seems kind of scary to fix, any do-it-yourselfer can tackle this fix. Here’s how:

  1. Check the water pressure coming into your machine
  2. If the pressure is weak, make sure to check your water pressure coming from your home
    1. Since there could be different reasons as to what the problem is, it is difficult to give clear cut instructions to fix it
  3. If the pressure is fine, then the problem could be the flow meter
    1. If so, you can order that part on Amazon or buy it from an appliance store

Bosch Dishwasher Error Code E15

This error code means that there is no water in the dishwasher. In our research, we saw that quite a few people said that tipping your dishwasher to move the water will clear the error code. While this fix will work, but it is only temporary. Tipping the machine causes the water to pool up which will trigger a sensor to reset the code, but the problem won’t actually be fixed. So the fix below will solve the problem.

  1. Again, power off your dishwasher and unplug it
  2. Next, open your machine’s door and unscrew it, removing it from the appliance itself
  3. Now you will need to remove your front plate towards the bottom of the appliance, which should have about 2 to 4 screws to remove
  4. After you remove the front panel pull out the insulation to reveal the actual base to your dishwasher
    1. This isn’t as nerve-wracking as it may sound, it is very easy to pull out in one bunch
  5. What you will be looking for is the micro-switch. The device itself will have 2 blue wires attached to it, which is really the only identifying factor to it
  6. Remove the cover from the switch and then clean off the styrofoam disk next to the switch
    1. This is what triggers the code to pop up
  7. After cleaning up the disk put it back where it was and reassemble your dishwasher (make sure you remember to put the cap back on the micro-switch)

Bosch Dishwasher Error Code E09

This final error code has to deal with the temperature and your appliance could be overheating. This is the only fix in this guide that might not actually fix the problem, in which case you might need to do a little extra research on the problem. Here is the most common fix for error code E09:

  1. Power your dishwasher off and unplug it
  2. Keep it unplugged for about 1 to 2 minutes
  3. Plug your dishwasher back up and see if that code is still there

If it is, then you might have to actually replace the circuit board. I highly recommend checking with your appliance store or even contacting their customer service for help if the code is still there. That way you aren’t voiding any warranties and aren’t making any major mistakes. If the code is gone then you’re golden!
