How to unblock the spray arm:

  • Bosch dishwasher has two sorry arms, the upper and lower spray arm. The upper spray arm is held in place by a screw. Unscrew the upper spray and dismount the lower spray arm
  • Unclog the spray arm nozzle by using materials such as toothpicks, tweezers, or similar material
  • Next, place the spray arm under running water and rinse thoroughly. Ensure all residual dirt is removed from the nozzle
  • Place the upper and lower arm back in position. Secure the upper arm with a clip.

The spray issues should be fixed after this. Test run to ensure there is an even distribution of water.

Low Heat

The non-availability of water at the very start of the wash cycle causes the problem of the bosch dishwasher not rinsing soap. This is attributed to the temperature of the water.

The optimal temperature of water for bosch dishwashers is temperature starting from 120F.

How to Fix Low Heat

The house water heater should be monitored serially to ensure the water temperature is kept within the optimal range.

Low Water Pressure

The cleaning power of the bosch dishwasher is highly dependent on the water pressure. Bosch dishwashers have an inlet valve that controls the release of water. The valve on the other hand can only be opened by a water pressure of at least 20 psi and above.

Water pressure below this may fail to open the inlet valve sufficient enough to let out water. This reduces the cleaning power of the machine considerably.

How to Fix Low Water Pressure

Problems with water pressure are traced back to the central home water system. This may require expertise to fix.

Faulty inlet valve

Sometimes, the problem with the inlet valve is not low water pressure, rather the valve itself may be fair. Problems such as bosch dishwasher not rinsing soap can be traced to a faulty inlet valve. While attempting to identify the cause of the problem, inspect the inlet valve for signs of damage.

How to Fix Faulty Inlet Valve

If the inlet valve is broken, it will need to be replaced or fixed immediately.

Alternatively, the problem of the bosch dishwasher not rinsing soap can be resolved by installing a rinse aid. Visit the user manual guide of the Bosch dishwasher to find out how to install the rinse aid.

The filter of the bosch dishwasher helps to rinse soap properly from dishes inside the dishwasher. Due to continuous usage, the filter might get damaged, making the bosch dishwasher not rinse soap properly again. But in many cases, the filter gets clogged, with debris, thereby blocking sufficient water from reaching the dishes and rinsing them properly. How do you fix this?

To remove tough clumps of food or mineral deposits, dunk the brush in mild dishwashing liquid or dishwasher detergent powder. Clean the filter housing and rinse the filter to remove any soap scum.

There might be a lot of filters within the dishwasher. Consult the manual or look up the model number online to find the filters and discover how to properly clean them.

Problem with the detergent dispenser

One of the primary causes of the bosch dishwasher not cleaning is a problem with the detergent dispenser. This is the component of the bosch dishwasher that releases the detergent or soap mixture used in cleaning the dishes.

When this happens, some of the dishes may block the spray arm and reduce the cleaning capacity of the dishwasher.
