No. The load should leave the intended movement and spray route clear. A large plate that physically fits between racks can still obstruct an arm.
Understanding this situation
Use the model's height-adjustment and loading options where supported. Removing a spray arm to make room is not an approved workaround, and a repetitive knock should not be ignored.
A useful next step
Check clearance before starting with the appliance stopped. Reposition or wash the item separately if necessary. If noise or poor cleaning persists after correct loading, report that pattern instead of assuming every knock is caused by crockery.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
