Do You Have a Bosch Dishwasher That Won’t Drain?

Drainage problems in a dishwasher can be very frustrating. In a dishwasher, water is supposed to drain thoroughly to make sure your dishes are clean. Otherwise, food particles and debris may accumulate in the stagnant water. This can lead to health issues down the line.

Your Bosch dishwasher should be able to drain water correctly. Typically, water should drain through the drain pump. It is usually connected to the dishwasher through a hose. The water escapes the dishwasher through the hose to the disposal area. If this system is not well-connected, then you might find yourself with some drainage problems. In most cases, it means that there are possible blockages that are affecting the free flow of water.

The best solution if this happens is to troubleshoot until you discover the real cause. If you need more help, please contact our helpline to discuss your Bosch dishwasher repair.

There are some recommended steps when troubleshooting. Ideally, the entire procedure will involve checking on the filter, the air gap and the drain hose.

Bosch Dishwasher That Won’t Drain

Checking on the filter

A filter is usually fitted at the bottom of the Bosch dishwasher to prevent food particles or debris from passing through the drain hose. This is a preventative measure to ensure you do not experience drainage problems with your dishwasher. However, some particles may still pass and clog the drain hose. Hence, it is vital to check whether this part is clean. If it is blocked, then remove the debris and clean it thoroughly to improve the drainage of the dishwasher.

Cleaning the filter is the easy bit. You can get some tutorials online for this and learn the necessary skills in filter cleaning.

Checking for blockages in the air gap

In most Bosch dishwashers, drainage issues are usually as a result of blockages occurring in the air gap. This is as a result of food particles being trapped here. The particles could be small with enormous repercussions. It is therefore vital to know how best to correct this problem as soon as it occurs. Luckily, it is quite easy to rectify the problem.

  • Reach out to the back of your sink and feel a small hood or cylinder (the air gap).
  • Once you have located your air gap, you should remove its cover. You can open this with your bare hands. In other instances, you could be forced to unscrew it to have it loose enough to open.
  • Remove the top part of the air gap by depressing the hooks. This will then allow you to clean the air gap and to remove any small debris that could be trapped.

When thoroughly cleaned, your Bosch dishwasher should drain thoroughly. Under normal circumstances, water from the dishwasher drains through the hose. The water passes through the air gap. When small particles get trapped here, it affects the working of the hose hence causing a drainage problem. Once you have cleaned out the air gap, you should try to run water through and see whether it will drain.

Blockages in the Drain Hose

At the countertop, there is a long drain pipe that runs to the garbage disposal. It is known as the drain loop. What you need to do in this case is to remove the food particles from the drain loop. However, you first need to separate the air gap from the drain hose. This is a small procedure that requires you to have a bucket ready to hold the water that could be held up. You can use a screwdriver to open the bolts.

Proceed and disconnect the drain hose from the air gap. Be on standby with the bucket to hold the water that will come pouring.

Once the water is fully drained, try to unblock the hose.

Once done, try to find out if the process has been efficient. This is by running water through the cycle and trying to drain it. Ideally, the water should flow. If water is still being retained, it means that the hose is still blocked.

Now you know what to do if your bosch dishwasher is unable to drain water. It is easy to troubleshoot the problems and clean these parts.
