Important Tips for Miele Models

Miele dishwashers do not require preâ€‘rinsing; only large food particles should be scraped to allow sensors to detect soil properly.
Filter maintenance is often prompted by a display message (e.g., after ~50 cycles); follow manual instructions to clean to maintain performance.

Possible Causes

Clogged or dirty filter reducing water flow

How to Identify: Food particles visible on filter, slow draining water, dishes still grimy

Part: Filter assembly

Improper detergent type or dispenser malfunction

How to Identify: Detergent not dispensing fully or prematurely dissolves, dishes remain soapy or dirty

Part: Detergent dispenser system

Low water temperature or wrong cycle selection

How to Identify: Using low-temp or quick/eco cycles with heavy soils not removed

Part: Wash program/temperature control

Water pump or heating element faults

How to Identify: Dishwasher fills but water isnâ€™t projected with force; water not reaching proper temp

Part: Water circulation pump/heating element
