Most modern dishwashers pause the selected wash cycle when the dishwasher door is opened, say to add a dish to the wash load before the dishwasher releases the soap. For many brands and models, the paused wash cycle will automatically start back up where it left off once the door is latched closed. Sometimes machines get old and must be replaced with new ones, other times you move into a new home supplied with Bosch appliances. Some new Bosch owners discover, rather costly so, that many Bosch dishwashers models do not automatically start back up or un-pause when the door is shut.

The common complaint concerning this Bosch dishwasher problem is: the power button is red, but the dishwasher doesnt do anything. I turned the machine off and on, but that didnt fix it. I think the pump is broken. Before going for a replacement pump or motor, find out if a wash cycle was simply interrupted or paused.

Bosch Dishwasher Not Draining Properly – How to Fix

The final step in Bosch dishwasher troubleshooting involves checking an air gap or garbage disposal for clogs. If you have one of these components, they share a common drain with the dishwasher. Consequently, if either become clogged with debris, food particles can block the shared drain and prevent dishwasher water from exiting.

Always run a garbage disposal before starting your dishwasher to clear it of any food scraps that can clog the drain. If you have an air gap, clean it regularly by removing the cover and wiping away any visible debris with a paper towel.

If you still find your Bosch dishwasher not draining water or your dishwasher leaves dishes wet, Appliance Service Station can help. Schedule a fast and reliable repair with one of our expert technicians!

Why Is There Standing Water At The Bottom Of The Dishwasher

The reason why there is water standing at the boom of the dishwasher is that your dishwasher is not draining properly as it should. The likely culprit could be a blocked drain hose. If the drain hose is not draining used water from the drain hose, then it will have nowhere else to go and will thus settle on the bottom of the machine.

Another likely reason why there is water at the bottom of your dishwasher is that the filter is clogged thus unable to allow the free flow of water. A damaged drain pump could also cause water to settle at the bottom of the machine.

In the case of a brand new dishwasher, water standing at the bottom of the dishwasher is mostly due to testing before shipping. This ensures that no malfunctioning appliances are delivered to clients.
