Bosch Dishwasher Error Code E15 Causes

Bosch Dishwasher Error Code E15 Causes

Let’s dig into what’s causing that pesky E15 error on your Bosch dishwasher. Here are the common culprits. 

Inappropriate Detergent Usage

Using the wrong detergent can spell trouble.

Certain detergents might not go well with your Bosch dishwasher, creating excessive suds or failing to dissolve properly. 

This can lead to water building up where it shouldn’t, triggering the E15 error.

Excessive Detergent

Excessive Detergent

Did you go a bit overboard with the detergent pouring? Too much of a good thing can turn into a foamy disaster. 

When there’s an overflow of suds, they can escape their designated areas and find their way into the nooks and crannies of your dishwasher, activating that E15 error code.

Clogged or Damaged Spray Arms

Those spray arms in your dishwasher work hard to distribute water evenly. 

But if they get clogged with food particles or suffer damage, they won’t do their job effectively. 

This can lead to water spraying in the wrong places, including the base of your dishwasher. And that’s when the E15 error occurs.

Sneaky Leaks 

Leaky troubles can be a pain! There are a few sneaky leak sources that can trigger the E15 error:

Leaking Sump Basin: 

Leaking Sump Basin

Over time, the sump basin where the trusty filter resides can develop leaks. 

When there’s a leak, water finds its way out and pools in the base of your dishwasher, triggering the error.

Leaking Hoses:

Those plumbing hoses in your dishwasher can cause trouble too. If they have cracks or damage, they become leaky culprits. 

Water takes advantage of these weaknesses and finds its way to the base of your dishwasher.

Leaking Water Tank: 

Yep – the water tank itself might be the source of the issue. Cracks or faulty seals can lead to water leakage. 

Instead of staying contained, the water escapes and ends up pooling in the base of your dishwasher, leading to the error.

Now that we’ve got the root causes sorted, let’s move on to fixing the issue.
