This article explains simple Bosch Dishwasher Troubleshooting procedures you can do in your home before you call for professional service.

Bosch is number one manufacturer of the high-end dishwashers that give you the choice of flexibility, cycle options, and quiet operation. But even the best dishwashers are not perfect. When your Bosch dishwasher stops working, there are few steps you can do to troubleshoot and possible solve the problems.

• Bosch dishwasher is not cleaning dishes:

  Make sure that the dishwasher is filling up with water. Also, check for clogged spray arms, drain filter and the circulation pump operations. One of the most common problems is the white residue on the dishes after the dishes being washed. This is due to the lack of phosphates in dishwasher detergents, and simply changing the detergent might solve this problem.

• Bosch dishwasher is not draining:

  If your Bosch dishwasher experience the drain issue it will display E24 or E25 error. First thing to do is to check for the clogged air gap. The air gap provides back-flow prevention for an installed dishwasher. To clean it, simply remove the top of the air gap and clean the accumulated debris. If the problem persist, you might have an issue with the clogged drain hose or failed  drain pump. In that case you should look for Bosch Dishwasher Service.

• Bosch dishwasher is making noise:

  The most common cause will be the accumulated water in the dishwasher base that activates the safety switch. The drain pump will run all the time and the program can not be switched off. The display will usually show errors such as E15 or E17.  If you don’t see the obvious reason for the water leak in to the base, call for service.

• Bosch dishwasher is not dispensing soap:

  If your Bosch dishwasher is not spraying water the soap will not dissolve. Check for the clogged spray arms, drain filter and for the circulation pump operation. If your detergent dispenser will not open it’s either due to faulty dispenser or the faulty heather circuit. In any case you should call for service.

• Bosch dishwasher is overflowing:

  Your dishwasher might overfill with water even if it is not in use.  This is due to the faulty water inlet valve. The solenoid part of the valve fails to shut off and  the water keeps entering the dishwasher. The only way to stop the water filling up your dishwasher is to find the water supply shut off valve and to turn the water supply off. The shut off valve is usually under the kitchen main sink. To replace the valve you will need to call Bosch dishwasher professional service.

If you’re not certain that you can safely perform these simple troubleshooting steps our advice is to call for Bosch Dishwasher Service.
