Miele Dishwasher: not spraying

Professional Repair Guide

What is this symptom?

If your Miele dishwasher isn’t spraying water effectively during the wash cycle, it can lead to poorly cleaned dishes. This issue may stem from clogged spray arm jets, a dirty filter, or even low water pressure. Proper maintenance and troubleshooting can help restore your dishwasher's functionality.

Urgency: Medium

Important Tips for Miele Models

  • Miele’s official support guidance describes blockage of spray arms by dishes or clogged jets and provides removal and cleaning steps. If the dishwasher displays a "Spray arm blocked" indicator, follow model-specific removal instructions.

Possible Causes

Clogged spray arm jets with food debris or mineral deposits

How to Identify: Visible food particles or deposits in spray arm holes; spray arms do not spin freely by hand; dishes remain dirty after cycle.

Part: Spray arms (upper/middle/lower)

Dirty or clogged filter / sump area reducing water flow

How to Identify: Slow drainage, visible debris in filter, reduced water circulation.

Part: Filter assembly / sump

Low water pressure or inadequate inlet flow

How to Identify: Dishwasher fills slowly or with insufficient water, weak spray, possibly accompanied by water supply warning codes.

Part: Water inlet valve / household supply

Faulty circulation pump or impeller

How to Identify: Humming without spray action, very weak or no water movement even after cleaning arms and filters.

Part: Circulation pump / impeller
