Bosch dishwasher error code E22

Bosch dishwasher error code E22. If you see the Bosch Dishwasher E22 error code, there might be a problem with the drain filter.

As it eats away at food residue throughout its lifetime, the drain filter can develop a buildup of calcium that clogs up its pores, making it unable to do what it’s supposed to do: pump water from inside the dishwasher out of the drain being used for disposing of waste into your septic system or municipal sewer.

As a general rule, we recommend you take apart and clean these components once every six months to avoid any Bosch Dishwasher E22 error codes in the future.

However, please remember your local plumbing or building codes may vary -it is always wise to double check with your local building inspector before starting work on your new kitchen!

We will discuss here the reasons for dishwasher error code e22.

Drain Filter

The Bosch dishwasher E22 error code is a common problem with the drain filter. If a Bosch dishwasher has a clogged filter, you will not be able to run the machine.

To ensure that dishwashers are working properly and continue to last for years, it’s important to protect them from clogs and stoppages, which can cause serious problems or even lead to expensive repairs.

Blocked Hose

Dishwashers feature a clever safety net called the non-return valve. When you’re done, if there are any problems with the drain hose, you won’t have to worry about dirty water trickling back into your dishwasher.

Once it has been pushed open, the valve opens up completely and can’t be closed again. So essentially, this little device acts as an extra ‘safety net in case of any issues with the drain hose.

If a clog or obstruction in the Bosch dishwasher E22 error code is triggered, a backup of wastewater into the machine can lead to damage as the water rises higher and higher inside the machine.

Circulation Pump Clog

A clogged or non-working circulation pump can also cause the Bosch dishwasher E22 error code.

You know how important it is to have a clean dishwasher, and that is exactly why you use Bosch appliances, but no one is immune to problems from time to time.

Circulation pumps circulate water in dishwashers to create a washing action. They must supply the wash arms with sufficient pressure and water to clean dishes thoroughly.

If a dishwasher doesn’t have enough water to wash the dishes, it will not be able to clean them as well.

A partial clog in the circulation pump means that during each cycle, some of your dirty dinner dishes will still contain residue instead of being washed away with each wash cycle.

To fix this problem inside your Bosch dishwasher, see if you can clear out any debris that may have caked up around your dishwasher’s pipes – and then run a test wash cycle to check if your issue has been resolved!


How can I resolve the E22 error code on my Bosch dishwasher?

When a Bosch dishwasher displays an E22 error code, you can solve the issue by cleaning the dishwasher filter. The filter is accessed inside the machine by removing the rack and spray arms.

If cleaning the dishwasher doesn’t do the trick, check for blockage or damage to the pump, valve, and drain hose.

How can I tell if my Bosch dishwasher drain pump is broken?

Designed to force water through the drain hose, a pump should not fail because it is easy to test workability using a multimeter for continuity check.

Continuous running of the motor will help avoid getting clogged together with eventual problems from stopping up earlier than anticipated and requiring emergency draining.
