Can I clean my dishwasher filter under the tap?

Yes, for most removable dishwasher filters, rinsing under running water is part of normal cleaning. We recommend checking your appliance manual first, particularly if the filter design is unfamiliar. A soft brush can help remove stubborn residue without damaging the filter mesh.

Why is my dishwasher still dirty after I cleaned the filter?

A clogged filter is only one possible cause. We also see poor cleaning caused by blocked spray arms, drainage faults, water-flow problems and faulty components. If cleaning the filter does not improve performance, further inspection can help identify the actual fault.

What should I do if my dishwasher filter is damaged?

A cracked, distorted or damaged filter may need replacing rather than cleaning. We recommend checking the appliance model number before ordering a replacement so the part fits correctly. Our team can also help identify suitable appliance spare parts for major dishwasher brands.

Can a blocked filter stop a dishwasher from draining?

It can contribute to drainage problems, particularly when food and debris restrict water flow or reach the pump area. If water remains in the dishwasher after you clean the filter, we can inspect the drainage system and check for problems with the pump, hose or other components.

How To Clean Your Dishwasher Filter

On most dishwashers, the filter sits at the bottom of the wash compartment underneath the lower basket. It is usually positioned around or near the base of the lower spray arm.

Start by switching the dishwasher off and pulling the lower rack out so you can see the base clearly. Many common models use a round or cylindrical filter that twists to unlock, sometimes with a separate flat filter underneath. The exact design varies between brands and models, so check the appliance manual if the filter does not release easily.

Never force the filter. If you cannot work out how it comes apart, finding the model-specific instructions is safer than twisting or pulling harder.

A dirty filter usually has visible food particles, grease or residue trapped across the mesh or around the filter housing. In some cases, the build-up may look like a greasy film rather than an obvious blockage.

A clogged filter can also show up through changes in dishwasher performance. Common signs include:

Food remaining on plates after a cycle
Grit or residue left on glasses and dishes
Unpleasant smells inside the dishwasher
Water sitting around the filter area
Slower or incomplete drainage

If your dishwasher is not cleaning properly, checking the filter is a sensible first maintenance step. Eurocoast’s dishwasher repair information also lists clogged filters among the potential causes of poor cleaning and drainage problems.

There is no single cleaning interval that applies to every dishwasher because usage and manufacturer recommendations vary.

If the dishwasher runs daily, handles heavily soiled dishes or regularly collects visible food debris, the filter may need attention more often. Some manufacturers recommend inspecting or cleaning filters weekly, while other models may need it less frequently depending on use.

A practical approach is to check the filter regularly and clean it whenever you see food, grease or residue building up.

As part of broader dishwasher maintenance tips, scrape large food scraps from plates before loading, keep the spray-arm holes clear and periodically check the bottom of the dishwasher for trapped debris. The appliance manual should always take priority for model-specific maintenance instructions.

A heavily clogged filter may contribute to drainage problems by restricting the path between the wash area and the drainage system. Food debris can also reach other components and contribute to a blocked pump. Eurocoast identifies blocked filters, drain pumps and hoses among potential causes when a dishwasher will not drain properly.

If you are trying to work out how often to clean a dishwasher filter, do not wait until one of these symptoms appears. Regular checking is much easier than dealing with a filter that has become heavily clogged.

A clean filter will not solve every dishwasher fault.

If the appliance still leaves dishes dirty after the filter has been cleaned, the problem could involve blocked spray arms, low water flow, the heating system or another internal component. Drainage problems can also come from the pump or drain hose rather than the filter itself.

Avoid repeatedly dismantling parts of the dishwasher if the basic maintenance steps have not solved the issue. At that point, proper diagnosis can help identify whether a component needs cleaning, adjustment or replacement.

Replacement filters, seals, pumps and other components also need to match the appliance model. Using the model number helps identify compatible appliance spare parts, particularly when an existing component is worn or damaged.
