Bosch Dishwasher E18 Error Code

We are sure you will agree that your dishwasher makes life a little easier for you after meal times doesn't it? This is especially true when you've cooked a large family meal, as it then solves the much-debated question of “Who’s turn is it for the washing up tonight?”

Like any appliance at home, your dishwasher could develop a fault at some point. If your Bosch dishwasher is sadly flashing an E18 error code at you, it is usually related to a low water level inside the dishwasher.

Following this guide should help you find the fault and assist you in getting the water flowing into your dishwasher once again.

Cause 1

Water Level Too Low

If the water level in the machine is too low, it can damage the water heating element and then lead to a poor cleaning performance.

Here we have some simple steps you can take to try to determine what exactly is causing the water level to be too low.

Safety First! Please ensure that you have disconnected the appliance from the mains before starting any repair.

  • Make sure the drain hose rises above the water level at the back of the machine to prevent water running out.
  • Check the water inlet valve is not restricted and check for faults using a multimeter.
  • Ensure the water supply flowing into the machine is not restricted.

These simple steps should help ensure that your dishwasher water levels rise up to the correct level.

You can soon be back to a fully working dishwasher again in no time, meaning there will be no need for you to have to continue to do the washing up by hand.
