Not Draining

If your machine not draining the water, first, you need to activate the "cancel drain" mode. There are two buttons on the control area. If you press those two at the same time, it will be reset and drain the machine for 90 seconds.

Make sure that the drain plug on the disposer has been removed, if you have recently installed the garbage disposer. A little plastic piece is there that blocks the hole where you hook the unit drain hose. Therefore, you have to check that disposer before start the dishwasher to make sure that the drain is clear.

One more suggestion is that there should be a high drain loop minimum about 18" off the ground with the drain line. It can prevent any backflow into the machine from the sink.

Sometimes small objects can get stuck in the pump. You should remove any debris buildup from the pump.

Water Not Filling?

Are you facing the problem with your dishwasher that there is no water entering? In such a case, you check the door latch, household water supply, the float switch, overfill protector, and the water inlet valve.

All of the water will be entered into the dishwasher through the inlet valve. If it is not close, you can disconnect the power machine and the flow of water. You have to replace the valve for debris or hard water build-up.

There is still some water in the pump but if it fills, although not in use, it may be diverting back through the drain, not drain properly, or a bad water inlet valve could signal this.

Poor Washing?

Troubleshooting of this problem is a very simple process with no need for any tools. Initially, you have to open the Bosch dishwasher rack and remove the bottom rack. Find out the top spray arm which is located under the top or middle rack. Pull that rack out by simply unscrewing the plastic lock unit counterclockwise. The bottom spray rack will remove easier.

You have to wash those two spray arms using a toothpick to unclog holes if they are clogged. Also, you can clean the filter at least a week. After that, back them into their positions when you are done.

Door Not Closing?

This problem will occur mainly due to blockage or even the upper and lower racks not sitting evenly. So, you have to first remove the bottom rack and try to close it. Later remove the upper rack and try closing. If that isn't the case and the door goes all the way to the top but not closing. Then you have to look at a door latch replacement.

Bad Quality of Washing Dishes

This problem may occur due to a user set an incorrect mode of operation and clogging of nozzles or any other annoying damages. It's not difficult for you to clean the nozzles on the rocker arms. If there are any foreign inclusions, carefully remove it with a toothpick.
