01 · BEFORE BOOKING
A simple check.
Make sure dishes do not block the spray arms or detergent dispenser. Follow the owner’s manual for cleaning a user-removable filter; use dishwasher detergent only.
02 · UNDERSTAND THE SYMPTOM
What it could mean.
Persistent poor cleaning can involve water filling, circulation, heating or dispensing. A completed cycle does not mean every part of the wash system worked correctly.
03 · THE NEXT STEP
When diagnosis helps.
I check the wash sequence and look for a supply, circulation or heating problem before recommending a repair.
This is general guidance, not a diagnosis of your appliance. Follow the owner’s manual for your exact model. Internal electrical, gas and refrigerant work belongs with a qualified professional.
