Bosch Dishwasher Error Codes: E15, E22, E01, E09 [Fixes]

Following up from a previous article we wrote here on a few of the most common error codes found in Bosch washing machines, we’re back today to hopefully help our readers out further by examining, and hopefully also assisting with, some of the most common error codes that can be found in the Bosch dishwashers.

As we mentioned previously, but it bears repeating, the machines themselves are equipped with a detection system to report when it detects faults within the machine itself, by displaying the error code, or codes, for the fault on the machine’s digital read-out – usually where the timer face is shown.

The code itself is usually shown as a combination of a letter (most often E or F) followed by two numbers. These codes should indicate what the issue is, and even where, it is emanating from. So the codes themselves will tell you exactly where you should start looking within the machine to service it.

In this article, we’re going to look specifically at four more of the most common error codes that might befall your Bosch dishwasher.

We will look at Bosch error codes E15, E22, E01, E09, and we will look at each of these errors one by one, hopefully providing you the guidance to resolve each of these errors in turn.

Error Code E15

Error code E15 means, simply, that there is no water in the dishwasher, or that the machine believes there is no water in the machine.

Many sources suggest that in order to resolve the issue, you would need only to pull the machine out and tilt the dishwasher back by forty-five degrees temporarily while pressing the machine’s power button to clear the error.

This will, indeed, clear the error temporarily, and allow the dishwasher to continue running.

However, in actual fact, this error means that it is likely that the machine is experiencing a very small leak, leading the water to collect in the base plate at the bottom of the machine. Once this water has collected, it triggers a Styrofoam float in the base, which then activates a micro switch, which then turns off the water inlet on the machine, triggering the E15 error code.

Tilting the machine back just tips some of the collected water out of the machine, resetting the float; this does not, in fact, solve the problem.

If you want more than a temporary solution and in order to properly fix the E15 error code, follow these simple instructions:

1. Turn off the dishwashing machine, and unplug the machine.

2. Open the dishwasher’s door, and unscrew the four screws holding the front of the door in place. Then slide the door off.

3. Next, you must remove two more screws holding the front’s lower base plate in place, and pry the cover off. Do be careful, though, as you will now have several screws exposed, which might easily injure you.

4. Now, you will need to remove the insulation behind the base plate. Carrying out this action will reveal the inside of the base of the machine.

5. In the center of the base, you will find a square plastic cover that holds the microswitch itself. The switch itself has two blue wires coming out, helping you to identify it.

6. You will now need to remove the plastic cover from the microswitch. To do so, begin to pry the cover from the right side, and the cover should come off.

7. Behind the microswitch itself, there is a Styrofoam disk, whose size is roughly four inches thick. Remove the disk and clean it off thoroughly.

8. Replace the disk in its place, and reassemble the machine.

The machine should now function as normal, and the E15 error code should now disappear.

Error Code E22

Error Code E22 signifies that there is residual water remaining in the dishwasher’s sump pump. In order to resolve the error, it is best that you check the pump for a blockage, and the machine’s filter as it may be dirty, particularly if it is functioning with a noticeable amount of grease or another type of build-up.

Any of these will prevent the machine from draining properly.

To check the filters, follow the following instructions:

1. Turn the machine off before proceeding to disassemble the machine.

2. Remove the bottom tray from the washing machine.

3. Below it, you will find the hexagonal filter, which should have a blue arrow at its front, indicating that the filter is locked into place.

4. Twisting the filter will unlock it, allowing you to remove it from the base of the machine.

5. Next, you can remove the metal plate at the base of the machine, revealing the outer part of the filter.

6. Next, clean the metal plate you have removed from the base of the machine, along with both portions of the filter.

7. If the filters have become too caked with dirt and grime, it would be better to replace them entirely than to place them back in the machine. Replacement filters are easily available on Amazon quite cheaply but do make sure you have both the inner and outer portion of the filter.

8. Now, once the filter is replaced, click it back into place, and replace the dishwasher’s lower rack.

The machine should now operate correctly. If it still does not, it may be that the pump itself has become blocked. To clear it, follow these instructions:

1. With the filters already removed (as above), pry off the pump cover until it clicks. Grip the cover by the lug and pull it upward until it resists, then pull it forward to remove it.

2. You can now clear out the pump itself, and remove any debris that may be clogging the pump and preventing it from draining properly.

3. Now, you can replace the pump cover, along with the filter, and the dishwasher’s lower rack.

The residual water should now drain from the dishwasher’s sump pump, and the error code E22 should now be resolved.

Error Code 01 or E1

Error code 01 or E1 means that your Bosch dishwasher is experiencing trouble with the motor. Specifically, this error signifies that you need to replace the power module because the motor controller has either stopped working or is malfunctioning.

Maybe It’s Malware?

If you’ve got computer problems, try some of the following software solutions:
  1. Malwarebytes: protects you against malware, ransomware, malicious websites, and other advanced online threats that have made traditional antivirus obsolete.
  2. Kaspersky Anti Virus: It is designed to protect users from malware and is primarily designed for computers running Microsoft Windows and macOS.
  3. Advanced SystemCare: It’s a Swiss Army Knife of a PC utility. It comes with a suite of optimization tools, including an uninstaller, one-click registry fixes, defragmenters, and more.

As with all the other errors that we are discussing in this article, you can easily fix error code 01 or E1 yourself.

In order to do so, simply follow these steps:

1. The first thing you will need to do is to turn off power in the dishwasher.

2. Then, carefully remove the toe kick panel with a screwdriver.

3. Once you have removed the panel, you will need to disconnect the dishwasher and pull it out. The reason behind this is the location of the power modules. You may expect the power models to be located right behind the fascia panels but you would be wrong, as they are in fact on the right side base of the dishwasher.

4. What you will need to do then is to find the base tabs holding the power module. There are two of them and they are made of plastic. Make sure that you pry the base tabs gently until the power module has been cleared. Once you have done that begin moving the bottom of the power module in order to clear the base and pull the power module from the base.

5. The final step requires you to pry the cover of the base taps until you open their cover. Once you have open the cover simply disconnect all the wire harnesses from the power module.

This should fix the error and your Bosch dishwasher should begin to function correctly after that.

Error Code 09

The last error in this article, error code 09, means that there is a problem affecting the temperature.

This video should help you deal with a faulty heating element- a popular fix on YouTube for this particular error.  

In order words, if you get this error on your Bosch dishwasher it would mean that there is a fault with the heating circuit due to overheating (this happens when the temperature rises to over 220° F.

If you would like to fix this error, follow these simple steps:

1. Disconnect the power cord from your Bosch dishwasher or tip the circuit breaker.2. Keep your Bosch dishwasher disconnected for, at least, 5 minutes.3. Connect your Bosch dishwasher again.

In many cases, this is enough for the error code 09 to disappear and your Bosch dishwasher to work just fine again. However, there is a chance that this will not work. If it does not, it means that there is a problem with the control board that is located inside the dishwasher door, specifically in the upper right-hand corner. If this is the case you will need to replace the control board.

As you can see, error codes E15, E22, E01, E09 are all relatively easy to fix once you know the what causes them and follow the steps we have laid out in this article carefully.

  1. Juan, I’m confused. You say that E:15 means there is water in the base plate caused by a small leak. So how does disassembling the machine and cleaning the styrofoam float fix the leak???

    • I was equally confused. The answer is that disassembling the machine and cleaning the styrofoam cup does not fix the leak. But if you do all this AND mop up any water in the base, it does fix the error. And that’s usually enough. The instructions for Error E01 are equally bad. Apparently, the way to fix a problem with the power harness is, I quote, to: “simply disconnect all the wire harnesses from the power module. This should fix the error and your Bosch dishwasher should begin to function correctly after that”.
      It’s a shame – this page is so close to being brilliant, but instead it’s just useless.

    • I must concur. The procedure is cumbersome to perform and not well explained at all : There are numerous imprecisions or errors. The door reinstallation is a pain in the *** and the cleaning of the disk does not solve any recurring leak ! Thanks for nothing !

  2. Hi My tenants have just notified me my Bosch dishwasher is also displaying the E15 Code and I am wondering if it is actually a small leak causing water to be trapped in the bottom of machine?? where is this leak coming from?? if it is a leak will it not happen again. ???
    I had to call the plumber out a few weeks ago due to kitchen drain blocking completely so is it possible the two problems are linked.? Plumber says sink blocked due to grease buildup in outlet pipe.

  3. I get many codes, the latest 09. I have read to disconnect or trip the breaker for 5 minutes. For what I paid for this hyped-up piece of junk, I should not be having any problem. It is less than 4 years old and I have had numerous problems. The silver “plastic trim piece” over the door handle has cracked twice. I had it replaced once and now have again used crazy glue to put it back in place. I will not sink another $ into trying to resolve issues with this machine, but will purchase another brand as soon as it quits, which most likely be soon. I am very disappointed with this Bosch considering they are rated high

  4. Totally agree with Linda, these Bosch dishwashers are rubbish. We’ve had ours less than 2 years….had E14 and E15 errors that required 3 service calls to resolve. Now we’re getting an E09. No way am I sinking more money into this lemon. We bought it on the back of Bosch having a good reputation….sorry Bosch your reputation is not deserved. Will NEVER purchase anything with the Bosch brand again.

    • Concur with Linda and Chris, Bosch is JUNK. My dishwasher is less than two years old and I have had numerous error codes. The repair service came out while it was still under warranty, but it took them WEEKS to schedule because they were so backed up. I only run light loads and I scrape everything off and rinse before using the dishwasher but it still doesn’t clean. E-22 clog error anyway… this is the worst piece of junk I’ve ever bought. Never ever again with Bosch, they are like Mercedes Benz. Very expensive and unreliable German Junk.

    • Interesting to hear this. Actually mine will be 3 years old in February 2018. Ten months in it threw me a code, think it was 22. The handle has cracked twice and now I have had an 09 code for the last 8 months. Dishes come out dirtier than when they went in and I rinse them first. I called the company and was told to reach out to them for some type of assistance with the cost. I was told I had to schedule a service call so they could diagnose. Thought that was the purpose of the code appearing. The service call is around $100 and then they will decide if I qualify for assistance, then the technician will return to fix it. If they won’t help then I am out approximately $250-300. No way! I plan on getting a new floor and this dishwasher will go to the garage. If I can’t unload it for $50, then it’s next stop will be the curb! Junk!

  5. After tearing the lower than normal counter top loose i found as stated the water had the round disc float raised just enough to give the E15 code, i removed the water then reset the washer it started and there i was watching to see where the water could be leaking from, then i seen it it was the outside of the cabinet supply hookup, look closely and it has a small drip catcher that puts the water in the pan under the dish washer, slight tighten of the supply line and she seems fine, something so small not even really a part of the dish washer but engineered so it would not leak on the floor but in the evap pan, Thanks for the help !

  6. e09 error came, i cheked the heating cerkit, it,s gone, later properly worked 3,4 times, now after sicle E14 error code coming

  7. My Bosch dishwasher is about two years old. I am getting E09 error codes, even after I recycled power. The dishes still come out clean. I read E09 is related to a malfunction with some heating circuit. The dishes come out clean and warm after each cycle. What is the dishwasher doing wrong or not doing that causes this error code?
