Bosch Dishwasher DLX Series Troubleshooting

In this guide, we are going to cover all the problems one can face while using the Bosch DLX series dishwasher, along with their solutions.

The Bosch dishwashers from the DLX line are quieter and spacious. Even the loudest dishwasher from the DLX series produces less operational sound and offers more space as compared to a conventional dishwasher in its price range.

Problem No. 1

The dishwasher is taking more time to complete the cycle

cold water problem for dishwasher

Reasons:

  • The higher soil level of the dishes causes the machine to take more time to complete the washing cycle
  • An empty rinse aid dispenser
  • Water coming from the water supply system is not warm, or the machine is attached to the cold water line

Solutions:

  1. Depending on the water condition and soil level of the dishes, the completion time of the washing cycle varies. The sensors detect the dirtiness of the dishes and increase the wash cycle time accordingly. To avoid this, rinse the dishes with water to reduce the soil level and then place them into the dishwasher.
  2. Load the rinse aid into the dispenser.
  3. Connect the dishwasher to the hot water line if not connected. And if the water coming from the system is not warm enough, open the hot water faucet for some time, allowing the water to turn hot.

Problem No. 2

The dishwasher is making noise during the wash cycle

Reason:

  • The only reason for this problem is that the dishes are not loaded appropriately into the dishwasher. If you find this error in Bosch dishwasher logixx, you can fix it by using the same method.

Solution:

Always load the dishes properly to avoid noise during the wash cycle. Make sure the items in the dishwasher are not blocking the spray arms. Always place small items on the top rack and large items on the bottom rack.

Problem No. 3

The dishwasher is not filling up the tank with water

Reasons:

  • You have pressed the delay start button
  • The water supply valve is off, or there is some blockage in the water supply line
  • The dishwasher hasn’t completed the previous wash cycle

Solutions:

  1. Canceling the delay start option is the only solution.
  2. Check the water supply line to find any blockage, or if the water supply valve is off, turn it on.
  3. Allow the machine to complete the wash cycle first, or you can cancel or change the cycle.

Problem No. 4

The dishwasher is not turning on

faulty door lock

Reasons:

  • The water supply valve is turned off
  • The Delay start option is activated
  • Child lock is switched on
  • You haven’t selected the wash cycle and closed the door
  • The dishwasher hasn’t completed the previous washing cycle
  • The machine is not getting the required voltage from the mains

Solutions:

  1. Check the water supply valve. If it is turned off, turn it on. Your dishwasher won’t turn on when there is no water supply.
  2. Reset the delay start function.
  3. If the child lock is on, turn it off to start the wash cycle.
  4. Select the wash cycle first before closing the door. Your dishwasher will never turn on when you close the door before selecting the desired wash cycle.
  5. Cancel or change the wash cycle.
  6. Check the incoming voltage, and if it is low or high, use the voltage regulator.

Problem No. 5

The dishwasher is not making the dishes clean

Reasons:

  • You have selected a wrong wash cycle
  • There might be a blockage in the filters
  • Limited spray arm movement or blockage in the nozzles of the spray arm
  • Dishes are not placed in a proper manner
  • Detergent is not being used properly

Solutions:

  1. Always select the wash cycle depending on the soil level of the dishes.
  2. If there is some blockage in the filter, remove it and rinse the filter mesh with water.
  3. If there is any blockage in the spray arm movement, remove it or if the nozzles are clogged, clean them so that the water reaches the dishes properly.
  4. Improper arrangement of the dishes inside the dishwasher also causes this problem. While loading the dishes, make sure you are loading them properly.
  5. The amount of detergent used depends on the hardness of the water. If the water is not that hard, decrease the amount of detergent and if the water is too hard, increase the detergent to get the desired washing results.

Problem No. 6

The dishwasher is not drying the dishes completely

Reasons:

  • Incorrect loading of the dishes causes drying problems
  • The selected wash cycle hasn’t the drying option
  • The rinse aid dispenser is vacant

Solutions:

  1. Always load the dishes in a proper way. Too many dishes in the dishwasher not only affect the washing performance but also the drying performance. There should be enough room for hot air to easily circulate around the dishes and make them dry.
  2. If you have chosen the wrong wash cycle (rinse/hold cycle), which has no drying option, select one that includes drying.
  3. Fill the rinse aid to improve the drying process.

Problem No. 7

The nasty smell coming out of the dishwasher

Reasons:

  • Blockage of the drain hose
  • Foreign objects or food particles are present at the bottom or near the door seal of the dishwasher
  • Dirty dishes are placed for too long inside the dishwasher
  • Residual water is stuck at the bottom

Solutions:

  1. If the drain hose is blocked or clogged, remove the blockage so that the dirty water can easily pass through the drain hose.
  2. Check and clean the filters and the door seal.
  3. Never put dirty dishes inside the dishwasher for too long. If you don’t want to run the wash cycle right away, select the rinse/hold cycle.
  4. The water must be entirely drained from the dishwasher after completing the cycle. If not, check the drainage system and remove any blockages.

Problem No. 8

Water is leaking out of the machine

broken arm of dishwasher causing leakage

Reasons:

  • The door seal is damaged
  • Suds
  • Blockage of the condensation vent
  • The dishwasher is not installed correctly

Solutions:

  1. Check the door seal and make sure it is not damaged. If it is damaged, replace the gasket.
  2. Always use a detergent made for the dishwasher to clean your dishes. Suds are formed when we use a detergent not made for the dishwasher resulting in water leakage.
  3. In case of a clogged condensation vent, eliminate the blockage.
  4. Incorrect installation of the dishwasher also causes the water to leak. Ask the technician to install the machine properly.

Problem No. 9

The display of the dishwasher doesn’t illuminate, or the controls are not visible

Reasons:

  • The door of the dishwasher is not completely closed.
  • A blown fuse or tripped circuit breaker

Solutions:

  1. Check the door of the dishwasher to make sure it is completely closed or locked.
  2. In case of a tripped circuit breaker, reset the breaker or if there is a problem with the fuse, replace it.

Problem No. 10

Stains on the interior box (tub) of the dishwasher

Reasons:

  • The incoming water is hard
  • When the silverware gets in contact with the tub, they leave stains.

Solutions:

  1. Install the water softener to make the hard water soft to avoid stains on the tub. If not, use concentrated lemon juice and place it on the top rack in the cup. Do this in between the cycle.
  2. Properly place silverware inside the dishwasher to avoid contact with the tub.
