What To Know

  • The air gap is a small device that prevents water from flowing back into the dishwasher from the sink drain.

A dishwasher is an essential kitchen appliance that saves you time and effort. However, it can be frustrating when your Bosch dishwasher is not draining properly. If you’re experiencing this issue, don’t worry. This comprehensive guide will help you troubleshoot and fix the problem.

Clogged Drain Hose

One of the most common reasons why a Bosch dishwasher doesn‘t drain is a clogged drain hose. Food particles, grease, and other debris can accumulate in the hose over time, causing a blockage.

To fix this issue, follow these steps:

1. Unplug the dishwasher from the power outlet.
2. Locate the drain hose, which is usually attached to the back of the dishwasher.
3. Disconnect the drain hose from the dishwasher and the sink drain.
4. Inspect the hose for any clogs. If you find any, use a plumber’s snake or a wire hanger to clear the blockage.
5. Reconnect the drain hose to the dishwasher and the sink drain.

Faulty Drain Pump

If the drain hose is clear, the problem may lie with the drain pump. The drain pump is responsible for pumping water out of the dishwasher. If it fails, the dishwasher will not be able to drain properly.

To test the drain pump, follow these steps:

1. Unplug the dishwasher from the power outlet.
2. Remove the lower access panel of the dishwasher.
3. Locate the drain pump, which is usually located at the bottom of the dishwasher.
4. Disconnect the wires from the drain pump.
5. Use a multimeter to test the drain pump for continuity. If the drain pump is faulty, it will need to be replaced.

Blocked Air Gap

The air gap is a small device that prevents water from flowing back into the dishwasher from the sink drain. If the air gap is blocked, it can cause the dishwasher to drain slowly or not at all.

To fix this issue, follow these steps:

1. Locate the air gap, which is usually installed on the countertop near the sink.
2. Remove the cap from the air gap.
3. Inspect the air gap for any clogs. If you find any, use a toothpick or a small brush to clear the blockage.
4. Replace the cap on the air gap.

Faulty Door Latch

The door latch is responsible for keeping the dishwasher door closed during the wash cycle. If the door latch is faulty, it can cause the dishwasher to leak water and not drain properly.

To test the door latch, follow these steps:

1. Open the dishwasher door.
2. Inspect the door latch for any damage or wear.
3. If the door latch is damaged or worn, it will need to be replaced.

Clogged Filter

The filter in the dishwasher traps food particles and other debris to prevent them from clogging the drain. If the filter is clogged, it can cause the dishwasher to drain slowly or not at all.

To clean the filter, follow these steps:

1. Unplug the dishwasher from the power outlet.
2. Remove the lower access panel of the dishwasher.
3. Locate the filter, which is usually located at the bottom of the dishwasher.
4. Remove the filter and clean it with hot water and a sponge.
5. Replace the filter in the dishwasher.

Faulty Control Board

The control board is the brain of the dishwasher. It controls all of the dishwasher’s functions, including the drain cycle. If the control board is faulty, it can cause the dishwasher to not drain properly.

To test the control board, you will need to use a multimeter. If the control board is faulty, it will need to be replaced.

Other Possible Causes

If you have tried all of the above solutions and your Bosch dishwasher is still not draining, there may be another issue that is causing the problem. Some other possible causes include:

  • A faulty water inlet valve
  • A clogged spray arm
  • A leak in the dishwasher door
  • A problem with the electrical wiring

If you are unable to find and fix the problem yourself, you should contact a qualified appliance repair technician for assistance.

Wrap-Up

If your Bosch dishwasher is not draining properly, it can be a frustrating experience. However, by following the steps outlined in this guide, you should be able to troubleshoot and fix the problem yourself. If you are unable to fix the problem yourself, you should contact a qualified appliance repair technician for assistance.
