Bosch Dishwasher E23 Error: An Incoming Mess!

Has your Bosch dishwasher been annoying you lately by taking forever to clean only to leave you with less-than-perfectly clean dishes? 

If so, you might have bumped into the E23 Error, especially if you’re also getting random puddles near the washer. 

What does E23 mean on a Bosch dishwasher, you ask?

Bosch Dishwasher E23 Error is a result of a clogged drain pump or a straight-up faulty one. That means the one your dishwasher has is due for a cleaning or a replacement, either of which can fix the washer right up.

Let me show you how to take care of this error and bring your dishwasher back up to speed again before it floods your kitchen with spills.

What Causes Bosch Dishwasher E23 Error

What Causes Bosch Dishwasher E23 Error

The Bosch Dishwasher E23 error happens when something goes wrong with the drain pump. 

And when it does happen, you end up with a janky wash cycle and plenty of water on the floor. 

Let’s look at the two main reasons for this error:

Blocked or Clogged Drain Pump

One common reason for the E23 error is when the drain pump gets blocked or clogged. 

Over time, bits of food and other stuff can build up inside the pump, making it hard for the dishwasher to get rid of water. 

When this happens, the dishwasher can’t drain properly, and that’s when the E23 error shows up.

Faulty Drain Pump

Now, let’s talk about another culprit – a faulty drain pump. Sometimes, the poor thing just gets tired from all that hard work. 

Regular use can wear down its parts, like the impeller or motor, and that’s when it starts acting up. 

Electrical issues or damage to its wiring can also play a role in the pump’s malfunction. 

When it goes bad, you’ll have no choice but to swap it out with a new drain pump.
