Dishwasher Not Draining | First Racine Appliance Repair

Do you have a Bosch dishwasher not draining? In this article we will discuss a common problem with Bosch dishwashers that prevent them from draining. There are many things that will prevent a dishwasher from pumping the water out, but in this article we will cover this common easy to fix problem with Bosch dishwashers.

If you have read some of my other repair tips and articles you probably are aware that I am a big fan of Bosch dishwashers. So imagine my surprise after about six months when my Bosch dishwasher stopped draining the water out at the end of the cycle. I couldn’t imagine that a 6 month old dishwasher had a defective drain pump. So before I opened my toolbox and started taking the dishwasher apart, I racked my brain for what else it could be.

 

Like most dishwasher manufacturers today, Bosch dishwashers use a separate motor and pump assembly to remove the water from the dishwasher between cycles and at the end of the wash cycle. Over the years I have experienced dishwashers that would not pump out the water and found the problem was not in the dishwasher or the dishwasher pump, but the problem was related to the garbage disposal.

I can not tell you how many times I have heard about First Racine Appliance Repair the following from customers, “I installed a new garbage disposal and now my dishwasher will not pump out.” And it’s always the same problem. They neglected to remove the little metal or plastic plug in the disposal where the dishwasher drain line attaches to the garbage disposal. Disposal manufactures put this there because not all people who own garbage disposals have dishwashers. If you have a dishwasher that is connected to your garbage disposal and you install a new disposal,

this small plug must be removed using a nut driver from the outside and punching it into the disposal.

Well obviously this was not the problem with my dishwasher because I did not install a new garbage disposal. I use my garbage disposal a lot so I decided to check where the dishwasher drain line connects to the garbage disposal and lo and behold, there was a restriction.

As I mentioned earlier most dishwasher manufacturers use a separate motor and pump assembly to remove the water from the dishwasher. The pump on the Bosch dishwasher however is not very powerful. So if the opening in the garbage disposal gets filled with debris, the dishwasher pump does not have enough power to clean it out.
