Siemens Dishwasher Error Code E19 – Causes and Solutions

The E19 error code on Siemens dishwashers is basically related to the problem with the heat exchanger and the drain valve. It is different from the E15 error code, which is triggered when there is an overflow of water.

Worry not if you’re a beginner, as here we’ll go through fixing this problem in detail!


Solutions to Fix Siemens Dishwasher Error Code E19

Siemens has implemented state-of-the-art heat exchanger tech in its dishwashers, which is why it cleans the dishes to almost perfection with the least usage of power.

However, the addition of new technology means the addition of new equipment/parts, and so is the case here.

With this new heat exchanger technology comes additional drain valves and as water is circulated through the heat exchanger, if it is not drained properly, the dishwasher will give an error, coded as E19.

So basically, the error code e19 is related to the non-drainage of water in the heat exchanger of the Siemens dishwasher.

Now that we know the cause of the error e19, let’s proceed with methods to fix it:

Solution # 1: Replace the Drain Valve

To replace the drain valve of the heat exchanger, you need to remove the valve professionally, so as not to damage any other part.

Please note that you are not required to dismantle the heat exchanger to replace the drain valve as it can be done easily without that by following the below steps:

  1. So just look for the drain valve and then turn it clockwise.
  2. Once its limit is reached, put it out and replace it with the same drain valve.

Solution # 2: Clean the Heat Exchanger

If replacing the drain valve of the heat exchanger of your siemens dishwasher did not solve the problem, you may need to check the heat exchanger for any debris or other particles which might be causing the problem.

However, we recommend getting it checked by a professional only.
