A malfunctioning dishwasher can be a major inconvenience, especially when it’s not draining properly. If you’re facing this issue with your Zanussi dishwasher, don’t worry – you’re not alone. This blog post will delve into the common causes of dishwasher drainage problems and provide step-by-step instructions on how to fix them.
Possible Causes of Dishwasher Drainage Problems
- Clogged Filter: Food particles and debris can accumulate in the dishwasher filter, blocking the water flow.
- Kinked Drain Hose: The drain hose may become kinked or crushed, restricting water flow.
- Faulty Drain Pump: The drain pump is responsible for pumping water out of the dishwasher. A malfunctioning pump can prevent draining.
- Blocked Air Gap: The air gap is a device that prevents dirty water from flowing back into the clean water supply. A blocked air gap can cause drainage issues.
- Obstructed Drain Line: The drain line that connects the dishwasher to the sink may be blocked by food particles or other debris.
- Malfunctioning Control Board: The control board controls all aspects of the dishwasher’s operation, including draining. A faulty control board can lead to drainage problems.
- Other Mechanical Issues: Less common causes include damaged impeller blades, faulty wiring, or a clogged sump.
How to Fix a Dishwasher That’s Not Draining
1. Check the Filter
- Locate the filter at the bottom of the dishwasher.
- Remove the filter and clean it thoroughly with hot water and a cleaning brush.
2. Inspect the Drain Hose

- If the hose is kinked, straighten it out. If it’s crushed, replace it.
3. Test the Drain Pump
- Disconnect the drain hose from the dishwasher.

5. Unclog the Drain Line
