What Siemens Dishwasher E22 Error Code Means and How to Fix It
When one sees an E22 error code flashing on a Siemens dishwasher, well, freak out-not alone. This can be a pretty confusing common error, but we are here to break it down and get you doing dishes again in no time. Grab a cup of coffee, roll up your sleeves, and let’s figure this out together.
What Does the E22 Error Code Mean?
Basically, this Siemens E22 error code is saying that your filters in the dishwasher are dirty or clogged. In other words, the food particles, grease, and other gunk have piled up and clogged up the area where water was supposed to drain out. Your dishwasher is screaming, “Hey, I need cleaning in here!”
Well, it isn’t that bad. It’s one of those issues that are fixable, and you may not need a professional to take a peek at it.

Why Does It Happen?
Dishwashers are hardworking machines, but over time, tiny debris from food residuals can build up in the filters. No matter how well you might pre-clean your plates, there is always a chance of minute particles passing through. A clogged filter hinders the water flow and may cause an E22 error.
Besides, if you don’t clean your dishwasher very often, then grease, soap scum, and grime build up and create an effect that welcomes drainage issues.
How to Repair the Siemens Dishwasher E22 Error Code
Now you have an idea of what is going on, let us get down to business. Take these steps immediately:
- Switch Off the Power Safety first! Switch off your dishwasher and unplug the machine from the power source. If hardwired, switch off the circuit breaker. You do not want any surprises when working.
- Locate the Filter Open the dishwasher door and pull out the bottom dish rack. The filter will be located at the bottom of the machine, usually center. For Siemens, the filter is cylindrical in shape and easily removed by twisting counterclockwise.
- Inspect and Clean the Filter Take a quick look at the filter. If it’s caked with food debris, grease, or grime, then that might be your villain. Rinse the filter under warm water. For particularly stubborn grime, use a soft brush-an old toothbrush works very well-and a small amount of dish soap. Get it squeaky clean!
- Check Blockages in the Drain Area Remove the filter now and check below it for trapped debris. Clean food bits you may observe or any residual. Ensure that no internal parts are damaged while cleaning.
- Replace the Filter Put the filter in its place by twisting it to the right in order to screw it on. Check again to ensure it is snugly in place.
- Run a Test Cycle Turn the power back on and run a quick rinse cycle. If the dishwasher runs smoothly and the error code disappears, you’re good to go!
Preventing the E22 Error Code in the Future
Now that your dishwasher is back in action, here are a few tips to keep the E22 error from returning:
Clean the Filter Regularly: It’s good practice to start a routine habit of rinsing off the filter every few weeks to avoid some buildup. Place it in your phone-it’ll only take minutes.
Scrape Off Excess Food: Light rinsing won’t be always necessary, though scraping off all the bigger fragments of food particles from your plates before loading should go a way in avoiding blocking.
Perform a monthly maintenance wash: Place some dishwasher-cleaning solution or a cup of white vinegar inside and run an empty cycle. It helps dissolve grease and prevents grime from building up.
Check the Drain Hose: Every now and then, check the drain hose for kinks and blockages because these too could be a reason for affecting water drainage.
When to Call a Professional
If, after cleaning the filter and drain area, the E22 error still persists, then a serious problem could be a faulty drain pump or a clogged drain hose. This is the point where calling a Siemens technician or your trusted appliance repair professional is the best option.
Conclusion
At first sight, error code E22 may seem to be a real headache, but after a little cleaning and care, your Siemens dishwasher will again serve you perfectly. Save yourself from future interruptions and wash your dishes stress-free, all thanks to one good deed-regular maintenance.
