Dishwasher Not Cleaning Properly?
Dishes Still Dirty After the Wash Cycle?
If your dishwasher finishes a cycle but dishes remain soiled, the problem may involve a spray-arm issue, water circulation, a filter restriction, a water-heating problem, detergent or rinse performance, loading, a pump or circulation fault, or a control problem.

Why Are Dishes Still Dirty After the Cycle?
Poor cleaning can be an appliance fault or a loading and detergent issue. Possible appliance causes include a spray-arm problem, restricted water circulation, a blocked filter, a water-heating problem, a pump or circulation fault, or a control problem.
Unsuitable detergent, rinse aid that is empty, or racks packed so that spray cannot reach the load can leave residue even when the machine is working. An assessment is used to tell a genuine wash fault from a loading or detergent problem.
Signs Your Dishwasher Is Not Cleaning Properly
Food left on plates after a full cycle
Cloudy glasses or a film on crockery
Soil only on one side of the load
Grit collecting in the base
Wash feeling cold to the touch
Repeated extra cycles still leaving residue
Possible Causes of Poor Cleaning
Possible causes include the following. Dirty dishes do not prove a single component has failed.
- Spray-arm issue
- Water circulation problem
- Filter restriction
- Water-heating problem
- Detergent or rinse issue
- Loading issue
- Pump or circulation fault
- Control problem
Appliance Fault Versus Loading or Detergent
If spray arms cannot spin because a pan is blocking them, or tablets are sitting in a dry dispenser, the load can stay dirty even when the dishwasher is sound.
If you have already used a suitable detergent, avoided overloading, and cleaned a user-access filter, remaining soil is more likely to need diagnosis of circulation, spray, heating or control.
What Can You Safely Check First?
Clear a user-access filter if your model has one. Check that spray arms can turn freely by hand without removing them from the machine.
Do not overload racks. Confirm you are using dishwasher detergent, not washing-up liquid. Do not dismantle the circulation pump, heater or spray-arm hubs.

How Poor Cleaning Is Diagnosed
A technician can inspect spray-arm movement, filter and circulation paths, whether the wash is heating, and whether the selected programme is completing as designed.
The visit also considers loading and detergent only as part of diagnosis. Extra tablets on their own do not identify a failed part.
