  • Error: H3

Beko dishwashers are reliable and efficient appliances that make dishwashing easier. However, like any other appliance, they can experience errors or malfunctions. One of the most common errors in Beko dishwashers is Error H3, which refers to a problem with the diverter valve.

The diverter valve is responsible for directing water to different parts of the dishwasher during the wash cycle. If this valve is clogged or blocked, it can cause Error H3. Fortunately, fixing this error is relatively simple and does not require advanced technical knowledge.

Here are the steps to fix Error H3 in a Beko dishwasher:

  1. Check the proper functioning of the diverter valve: The diverter valve is located at the bottom of the dishwasher. Make sure it is in good condition and not obstructed by food debris or other objects. If you find any obstructions, carefully remove them using a soft brush or a damp cloth.
  2. Clean the diverter valve: If the diverter valve is clogged, you can try cleaning it to solve the problem. To do this, disconnect the dishwasher from the power source and close the water shut-off valve. Then, disassemble the diverter valve following the instructions in the dishwasher’s user manual. Clean the valve with warm water and mild detergent, making sure to remove any residue or dirt. Reassemble the valve and check if the error persists.
  3. Inspect the electronic card: In some cases, Error H3 can be caused by a fault in the dishwasher’s electronic card, specifically in triac T7. If you have checked the diverter valve and have not found any obstructions, it is advisable to inspect the electronic card for possible faults in triac T7. If you do not have experience in electronic repairs, it is recommended to contact an authorized service technician to perform this task.

It is important to note that Error H3 is not the only error code that can appear in a Beko dishwasher. Other common error codes include H2, which refers to a turbidity sensor error, H4, which indicates a problem with the temperature sensor, and H5, which is related to a water inlet error. Additionally, there are other error codes such as E01, which indicates no water entering the dishwasher, E02, which signals a water drainage anomaly, and E03/E08, which indicates the need to restart the wash cycle due to a temperature problem. Errors like E04, related to a water filling problem, E05, indicating a thermostat failure, and E06/E07, referring to a dishwasher thermometry problem, can also occur.

If you encounter any of these errors, it is recommended to consult the Beko dishwasher’s user manual or contact an authorized service technician for assistance and problem resolution.
