Dishwasher Not Cleaning
Poor cleaning can involve water, heat, spray, loading, detergent, drainage or control symptoms. The pattern of residue and the selected cycle help describe the issue.
Observe safely.
This guide describes useful clues, not a confirmed diagnosis. Parts, price and service availability need to be discussed from the appliance and location details.
What to note before you enquire.
- Note which programme and temperature were used.
- Describe whether dishes are dirty, wet, gritty or covered in detergent residue.
- Follow the model’s routine filter and spray-arm care instructions without forcing parts.
- Record whether water is left in the base or a warning appears.
Switch the appliance off for leaking water, burning smells, electrical trips or exposed water around a power connection.
Several causes can look alike.
- Spray arms, filters, loading and detergent can influence results.
- Water inlet, circulation, heating or drainage components may be involved.
- A programme or temperature change can alter the result.
- A single poor load does not confirm a component failure.
Details that reduce guesswork.
Useful details
- Model number, cycle and detergent used
- The pattern of poor cleaning and whether dishes are hot or wet
- Any code, water remaining, unusual noise or recent change
When to arrange an assessment
Arrange an assessment when cleaning remains poor after routine model instructions or the dishwasher stops, leaks or shows a warning.
Before you take the next step.
Should I run the dishwasher repeatedly to test it?
Avoid repeated cycles if it leaks, trips power, smells of burning or leaves significant water. Record the first clear symptom instead.
Can dirty dishes prove the spray pump has failed?
No. Loading, filters, water, heat, detergent and several components can affect cleaning. The full cycle behaviour matters.
Share the details safely.
Include the model, postcode, symptom and anything you observed without opening the appliance.
