Solution #1 Clean Drain Filter

The Drain Filter is used to remove solid particles from the water before draining it out.

These particles begin to accumulate and effectively block the filter, which is why you have the E22 bosch dishwasher error. 

Solution: Thoroughly clean your dishwasher's drainage filter if you haven't done so!

Here is how you can clean your dishwasher drain filter:

1. Unplug your Bosch Dishwasher from the outlet.
2. Open the Dishwasher Door and carefully pull out the Bottom Rack.
3. Then, remove the Spray Arms by pulling them up.
4. Pull out the Drain Filter by rotating it counterclockwise.
5. Next, lift out the Square Mesh Panel from the dishwasher basin.
6. Clean the fine filter and mesh panel by using soapy water.
7. Take an old toothbrush and properly clogged debris from the components.
8. Put the filter back in place first and rotate it clockwise to lock it.
9. Then fix the mesh panel and spray the arms back to their places.
10. Next, close the door and turn on the power.

Test by running a cycle to ensure whether or not the error has been resolved.

In case that helped you can now continue the cleaning cycle. If the problem persists, keep reading!

Solution #2 Remove Calcium Buildup

It’s possible that the area where you live has water supplies with a lot of naturally occurring minerals, especially Calcium.

That’s why calcium may build up in your dishwasher’s drain filter and prevent water from draining.

Therefore, you will still get an E22 error during the cleaning!

Here is how you can remove the calcium buildup from your dishwasher’s drain filter:

1. Empty your dishwasher from racks and utensils.
2. Then power on your Bosch Dishwasher.
3. Select the water temperature to Maximum.
4. Without adding any detergent, select the longest wash cycle. 
5. Allow the dishwasher to run for at least 30 minutes.

When the cycle is finished, add one box of Descaler directly into the dishwasher’s filter outlet and leave it for 10 minutes.

Finally, run a new wash cycle to clear all of the built-up calcium.

Tip: Make sure to clean your dishwasher filter at least 4 times a year by using a descaler!

Solution #3 Unclog Drain Hose

Sometimes, even when the hose is blocked, the water can easily drain from the filter but cannot exit the system.

Now that we know the error E22 is displayed when the water in the basin does not drain, our next primary suspect is the drain hose.

Let’s learn more!

All you need is to thoroughly clean the drain hose and non-return valve!

Here is how you can easily unclog the hose and valve:

1. Remove the dishwasher’s Lower Access Panel by unscrewing it.

1. Next, remove the screws of the outdoor panel from the door inside.
2. Pull out the Outdoor Panel and set it aside.
3. Flip off the Main Water Supply.
4. Disconnect the Brass Elbow from the drain Valve.
5. Next, disconnect the Valve and remove the Wiring Harness.
6. Separate the Clamp using a Plier and then disconnect the Valve.
7. Unclogged the drain Hose and Valve by passing the water pressure.
8. Replace the new drain hose if the previous one is fully clogged or leaked.
9. Lastly, fix back each component the way you separated.

To test whether the error has been resolved, run a wash cycle on the dishwasher!

Solution #4 Clean Circulation Pump

Not frequently, but occasionally, the Bosch Dishwasher’s blocked Circulation Pump causes the E22 error code.

This is one more of the components responsible for draining the dishwasher’s water so that it may be recycled within the dishwasher for cleaning.

Solution: All you need to do is to unblock the circulation pump from clogged materials!

Here is how you can clean your dishwasher’s circulation pump:

1. Open the Bosch Dishwasher Door.
2. Carefully remove the racks from the dishwasher.
3. To protect against broken parts, wear gloves on your hands. (Optional)
4. First, unscrew the Upper Spray Arms and pull them down.
5. Next, pull over the Lower Spray Arms.
6. Place the Spray Arms aside.
7. Wash the arms under warm water for 3 minutes.
8. Use a toothpick to properly clean the Arm Holes.
9. Fix back the upper arms to their place.
10. Clip the lower arms to fix them into place.
