In this article, we will explore some of the common causes of a Zanussi dishwasher not draining and the possible solutions.

Common causes of Zanussi dishwasher not draining

Several factors can cause a Zanussi dishwasher not to drain. Here are some of the most common causes:

  • Malfunctioning Drain Pump
  • Faulty Drain Solenoid
  • Broken Drain Impeller
  • Damaged Check Valve
  • Defective Timer
  • Broken Control Board
  • Clogged Air Gap

Clogged Drain Hose

A clogged drain hose is one of the most common causes of a Zanussi dishwasher not draining. Over time, food particles, soap scum, and grease can build up in the hose, preventing water from flowing out. If you suspect the drain hose is clogged, you can try cleaning it with a drain snake or a wire hanger.

Blocked Garbage Disposal

If your Zanussi dishwasher is connected to a garbage disposal, a clog in the disposal can cause the dishwasher not to drain. To fix this, switch off the garbage disposal and remove any debris from it. Afterward, run hot water down the disposal to flush out any remaining debris.

Malfunctioning Drain Pump

The drain pump is responsible for pumping out water from the dishwasher. A faulty drain pump can cause the dishwasher not to drain. You can check the pump for blockages and ensure the impeller is functioning correctly.

Faulty Drain Solenoid

The drain solenoid controls the drain valve, which allows water to flow out of the dishwasher. If the solenoid is defective, it can cause the valve not to open, preventing the dishwasher from draining.

Broken Drain Impeller

The drain impeller helps to pump out water from the dishwasher. If it is broken, the dishwasher may not drain. You can check the impeller by removing the dishwasher’s spray arm and inspecting it.

Damaged Check Valve

The check valve prevents water from flowing back into the dishwasher. If it is damaged, it can cause the dishwasher not to drain. Inspect the check valve for cracks or damages and replace it if necessary.

Defective Timer

The dishwasher timer controls the dishwasher’s cycles, including the drain cycle. If the timer is defective, it can prevent the dishwasher from draining correctly.

Broken Control Board

The control board regulates

the dishwasher’s functions, including the drain cycle. A faulty control board can cause various problems, including a Zanussi dishwasher not draining.

Clogged Air Gap

The air gap prevents wastewater from flowing back into the dishwasher. If it is clogged, it can cause the dishwasher not to drain. You can clean the air gap by removing the cap and cleaning any debris.
