Frustrated with a flashing E22 error code on your Bosch dishwasher? Before you call in an expensive repairman, take a few minutes to resolve the issue yourself. This guide will walk you through the simple steps to fix a bothersome E22 error. You’ll learn how to safely clean the filter and drain area, which are the most common causes of the error code. Armed with some basic tools and these easy directions, you can get your dishwasher running smoothly again without breaking the bank.
What You Need
To fix the E22 error code on your Bosch dishwasher, you will need a few basic tools and supplies. This section lists everything you should gather before starting.
Cleaning Brush

- Look for a brush with stiff, sturdy bristles. Soft bristles won’t clean as well.
- An old toothbrush works in a pinch, too!
Warm Water
- Warm, soapy water helps loosen gunk on the filter.
- Hot water from the tap is best. If it’s too cold, add some hot water from a kettle.
- Lukewarm water won’t dissolve grease as quickly.
Mild Soap
- Dish soap or another mild cleaner lifts stuck-on grime.
- Stay away from harsh chemicals that could damage parts.
- A drop or two of soap in warm water makes a good cleaning solution.

Finding the E22 Cause
This part walks through how to track down the reason for the E22 error code. Step-by-step directions break it down into easy stages.
Step 1: Remove the Filter
The filter traps gunk during wash cycles. Checking it first makes sense since clogs often trigger E22.
- Unplug the dishwasher. No power means no shock risks.
- Twist the water supply knobs off. This cuts water flow.
- Pull out the bottom rack for access. Less bending makes things easier.
- Turn the filter counterclockwise to loosen it. Lefty loosey!
- Pull straight out once loose. Avoid an angle or tube damage.
Step 2: Scrub the Filter
Is the filter gunky? Clearing clogs might solve E22.
- Separate the outer filter from the inner screen. More surface area to clean!
- Use that brush to scrub off stuck-on food scraps.
- Soak both parts in hot, soapy water. Let the solution do the work.
- Enable thorough drying. Water residue risks re-clogs.
Step 3: Put Back the Filter
Double-check that the filter and screen are gunk-free before replacing them.
- Push the filter back onto the inner screen. Teamwork makes the dream work!
- Insert the assembled piece into its slot. An angle helps it slide easier.
- Twist clockwise to lock it into place. Righty tighty secures things.
- If removed before, put back the lower spray arm. Crucial for full wash power!
- Slide the bottom rack loaded with dishes back in.
- Reconnect electricity and water. Necessities for test runs!
- Run a wash cycle. Does E22 rear its head again?
Avoiding Future E22 Errors
You fixed the immediate E22 error code. Great! But how can you stop it from popping up again? This part discusses tips to prevent more E22 headaches.
Clean the Filter After Each Wash
- Gunk builds up quickly with regular use.
- Get ahead of clogs before they block water flow.
- A fast rinse keeps the filter clear long-term.
Check the Drain Hose
- Kinks in the drain hose prevent water exit.
- Lay the hose as flat as possible with no tight bends.
- Smooth water flow avoids backup and E22.
Regular Sanitize Cycles
- Monthly sanitizing cycles blast grime inside.
- They refresh the dishwasher’s washing power.
- It’s like a deep clean for the appliance.
Use Baking Soda and Vinegar
- These homemade solutions dissolve stuck-on gunk.
- Coating the inside with baking soda and then running a hot vinegar cycle scrubs it sparkly.
- Search online for full directions.
Don’t Overload the Dishwasher
- Packing in too many dishes at once causes problems.
- Things don’t get fully clean, and water can’t circulate easily.
- Follow the loading guidelines in your user manual.
Use the Right Detergent
- Dishwasher detergent makes suds that break up grease.
- Hand washing soap creates excess suds that clog.
- The detergent dispenser has specific soap types. Stick to those.
Avoid Harsh Chemical Cleaners
- Bleach, acids, and degreasers seem like strong solutions.
- But they damage the inner workings over time.
- Soap and hot water work with fewer risks.
Check the Dispenser
- Detergent, rinse aid, and other excess get stuck.
- Soaking and then scrubbing keeps chemicals flowing freely.
- Follow the clog-clearing steps in the user guide.
