Bosch Dishwasher Not Draining Water – Coombabah

A customer in Coombabah contacted ISB Electrical because their Bosch dishwasher was not draining water. Water was left inside the dishwasher at the end of the cycle, and the machine could not complete normal operation.

When a Bosch dishwasher does not drain water, the fault can be caused by a blocked filter, blocked drain hose, faulty drain pump, broken impeller, blocked non-return valve, kitchen sink drainage restriction or a control fault. In this case, the drain system was inspected and the water drain pump was tested.

Inspection and Diagnosis

• Checked the dishwasher power supply and safety condition
• Confirmed water was remaining inside the dishwasher
• Checked the filter and sump area
• Inspected the drain hose for restriction
• Checked the drain pump operation
• Tested whether the pump was removing water correctly
• Checked for blockage or foreign objects around the pump area
• Confirmed the water drain pump was faulty

Fault Found

The fault was caused by a faulty water drain pump. The pump was not draining the water from the Bosch dishwasher correctly, leaving water inside the machine.

A faulty drain pump can cause the dishwasher to stop during the drain stage, leave dirty water inside, show a drain-related fault, or prevent the next cycle from starting properly.

Repair Completed

The faulty water drain pump was replaced. After the replacement, the Bosch dishwasher was tested through the drain stage to confirm the water was being removed correctly.

The dishwasher was then checked for normal operation, correct drainage and no further water remaining inside the sump area.

• Blocked filter or sump area
