What is the failure of Bosch error E19 affecting your dishwasher?

If you have a Bosch dishwasher, you may encounter the error code E19 on the display at some point. This code indicates a problem with the dishwasher's operation, which can be caused by various reasons.

The unfortunate news is that this error code can be somewhat challenging to resolve, so you'll need to read and check everything we're going to indicate in the list of possible solutions we've prepared for you. We'll explain what this error code might signify, its possible causes and solutions, and how to prevent it from happening again in the future.

The error code E19 refers to incorrect operation of the circulation pump or the heat exchanger valve. These are two important components of the dishwasher, responsible for circulating water inside the appliance and regulating its temperature. If either of these elements fails, the dishwasher won't be able to perform the washing cycle correctly and will display the E19 error code to alert you to a problem.

Some of the most common causes that can generate the E19 error code on your Bosch dishwasher include:

  • A problem with the solenoid valve: The solenoid valve is responsible for opening and closing the water inlet to the dishwasher. If it is damaged or blocked by a foreign object, it can prevent water from reaching the circulation pump or recirculation valve, causing the E19 error.
  • A problem with the pump: The pump may be damaged due to a blow, electrical overload, or wear and tear from use. It can also be clogged by food residues, limescale, sulfate, or dirt, preventing it from rotating correctly and pumping water with the proper pressure.
  • A problem with the dispenser: The dispenser is the compartment where detergent or tablets for washing are placed. If it is broken or not closed properly, it can cause a water leak or improper product dosing, affecting the dishwasher's operation and washing results.
  • A problem with one of the internal valves: The dishwasher has several internal valves that regulate the flow of water between different circuits and compartments. If any of these valves is damaged or stuck, it can prevent water from circulating correctly, leading to the E19 error.

How to fix error E19 on Bosch dishwasher?

If your Bosch dishwasher shows you error code E19 on its screen, you can try some possible solutions before calling for technical service. We will leave you here the solutions that we have been able to compile for you:

  1. Restart the dishwasher to reset the sensors: Sometimes, the E19 error can be a temporary system glitch that you can resolve by simply restarting the dishwasher. To do this, disconnect the dishwasher from the power outlet and wait for about 15 minutes before reconnecting it. Now, turn it on and start a short program to check if the error has disappeared. This way, we are confident that you will succeed in resetting the E19 error in your Bosch dishwasher.
  2. Clean the solenoid valve of the dishwasher: If you suspect that the solenoid valve is blocked by a foreign object, you can try cleaning it to free it. To do this, you'll need to disconnect the dishwasher, shut off the water supply, and access the back of the appliance. There you'll find the solenoid valve, which is a cylindrical piece with two cables and a hose. Carefully remove the hose and check for any object obstructing the water inlet. If so, remove it with tweezers or a wire. Then, reattach the hose and reconnect the dishwasher.
  3. Clean the pump of the dishwasher: If you believe that the pump is obstructed by food residues, sulfate, limescale, or dirt, you can clean it to improve its performance. To do this, disconnect the dishwasher, empty any remaining water inside, and access the bottom of the appliance. There you'll find the pump, which is a round piece with a propeller in the center. Remove the cover that covers it and check for any food remnants or dirt that may prevent it from rotating correctly. If so, carefully remove it and clean the pump with a damp cloth. Then, replace the cover and reconnect the dishwasher.
  4. Check the detergent dispenser in your dishwasher: If you think the dispenser is broken or not closed properly, you can inspect it to check its condition. Open the dishwasher door and locate the dispenser, which is usually on the interior of the door. Check for any cracks, breakage, or deformation that may cause a water leak or improper detergent dosing. Also, check if it closes correctly and if there is any product residue that may hinder its operation. If so, clean the dispenser with warm water and a damp cloth, make sure to close it properly before starting the wash cycle.
  5. Inspect the internal valves of your dishwasher: If you believe that any of the internal valves are damaged or stuck, you can check their condition to verify. Disconnect the dishwasher, empty any remaining water, and access the bottom of the appliance. There you'll find several valves that regulate the flow of water between different circuits and compartments. Check if they have any cracks, breakage, or deformation that may prevent them from opening and closing correctly. Also, check for any food residues, sulfate, limescale, or dirt that may block them. If so, clean the valves with a damp cloth, a little electronic cleaner, and make sure they function properly before reconnecting the dishwasher.
  6. If the problem persists, repeat all the previous steps: Perform a second check of everything we have indicated above. If after trying all possible solutions, the E19 error continues to appear on your Bosch dishwasher, it may be a more serious problem that requires professional intervention. In that case, we recommend not attempting to repair the dishwasher yourself, as you could cause more damage or put yourself at risk.
  7. Seek help from Bosch technical support to resolve the issue: If none of the above solutions has worked, it's best to contact the official Bosch technical support for repair assistance. They have the knowledge and tools needed to diagnose and resolve the problem efficiently and safely.

That would basically be it! You may find it a little complicated, but it is undoubtedly a problem that can have a solution. The error code E19 may have different reasons why it could appear on your dishwasher's screen, but if you are patient we are sure that you will get to the root of the problem. Otherwise, as a last option you can call Bosch technical support and they will help you solve this problem.
