Why Does My Bosch Dishwasher Soap Dispenser Not Open?

  • Soap Deposits

What dishwasher soap are you using in your Bosch dishwasher? It can be the main reason why your soap dispenser is not opening.

Using Cubed/gel pack dispenser detergents in your Bosch Dispenser is not advisable. Likewise, it is not advisable to use liquid detergents in the dispenser. It causes soap buildup to block the dispenser door from opening since the hinges aiding the closing and opening are clogged with soap.

You will find both dishwasher soap not dissolving if it lacks phosphate, which is the quality with these certain detergents. Instead, they will take a long time to dissolve, and if you keep adding soap to the dispenser, they clump together, making it impossible for the door to open.

  • Physical obstruction

Depending on the model, the bosch soap dispenser will not open because of a simple reason as something preventing the process. For example, there can be an improper stack of utensils.

  • Bi-metal loop

The loop is essential as it aids the door latch. Therefore, it controls the Bosch dispenser opening and closing mechanism. It is powered directly by electricity, so sometimes it can burn out, making the door bend away and the dispenser not open.

  • Broken detergent dispenser

The dispenser will stop functioning as it should when it gets damaged. A slight breakage or deformation may affect how the door operates in terms of opening and closing. If, for example, there is soap stuck inside, it can dry up and become so hard that it can cause some damage to the dispenser. You can physically check for such.

  • Dispenser Actuator

Like the bi-metal loop, the actuator is also electrically connected and is prone to damage. For it to function, it receives a proper signal for the dispenser lid operation. When damaged, you will get the bosch dishwasher soap dispenser not closing or opening.

  • Dispenser Cover

When the Bosch dishwasher detergent dispenser cover is damaged or broken, it is widespread because the surface is on the outer part. The soap buildup again affects the detergent dispenser cover as it makes it hard to allow the sliding of the lid to facilitate the soap dispenser opening and closing.

  • Dispenser door pins

If the door pins are not in the correct position, especially if it is the sliding door, it means the dispenser door will not be in its proper place. It means that the soap dispenser will not open.

The door spring supports the lid’s latch so the dispenser can open regularly. The cover will latch with a clicking sound; if not, the spring or the latch is faulty. The spring can be damaged or out of position, and it will have the dispenser not opening during the cycle.

  • Dispenser Lever

The lever is a white piece connecting to the actuator and the latch. It facilitates the opening of the dispenser lid by lifting the latch. When the liver is damaged, the dishwasher soap dispenser will not open.

  • Dispenser lid

The first thing to check in the lid is the soap deposits. Still, the cover can deform, making it hard for the soap dispenser to open.

  • Dispenser slide

The slide is the last thing you check, but mostly if it has a problem, it will be a problem with the soap deposits.

  • Main Control board

The control board is the overall brain of the Bosch dishwasher. If it has a problem, the dishwasher will misbehave in several ways, like the Bosch dishwasher soap dispenser not closing and not opening. It may cause the voltage supply failure to the detergent dispenser, thus not opening.
