How to Troubleshoot the Bosch Classixx Dishwasher

Updated November 21, 2016

The Bosch Classixx dishwasher has been primarily manufactured for distribution in Europe. It features a top rack cutlery basket, adjustable top rack, alternating spray arms, self-cleaning filtration system, prewash and quick rinse, LED indicators and four different wash programs. While the Bosch dishwasher should operate well with standard maintenance and care, problems may occur occasionally. If this happens, some troubleshooting may be useful to help you determine the problem.

  1. Ensure the Bosch Classixx dishwasher is plugged into a power outlet if it is not operating. Reset the circuit breaker or fuse if needed.

  2. Verify the water valve is turned on and the dishwasher door is closed completely if the dishwasher has power but is not operating.

  3. Turn off the dishwasher and the water supply if the dishwasher is not filling with water as expected. Remove the water line hose and clean the filter screen. Reconnect and restore power.

  4. Turn off and unplug the dishwasher if water remains in the dishwasher after the cycle is done. Remove the drain hose and clean away any possible obstructions. Reconnect the hose and power.

  5. Wipe the detergent dispenser with a dry cloth before use if there are clumps of detergent left in the dispenser. Use only the recommended detergent amount if there is an excess of suds in the dishwasher. Wipe up any spilt rinse aid detergent to prevent oversudsing.

  6. Redistribute items in the dishwasher to allow the spray arms to rotate if dishes are still dirty after the dishwasher is done. Ensure adequate detergent has been placed in the dispenser and select a new wash cycle for medium to heavy soil.

  7. Straighten out the water hoses and ensure the water valve is on if error code "6" appears on the display.
