Appliance Dishwasher
Quick answer

What to do when a Miele dishwasher displays F170.

Model compatibility

Miele reuses codes across series and model years, so F170 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

The dishwasher reports a lack of rinse aid.

F170 explained

Rinse aid has run short.

At a glance

Code F170
What it means The dishwasher reports a lack of rinse aid.
What you can check Add rinse aid before the dispenser runs completely empty, then press OK to confirm. Open the reservoir with the yellow button on its lid, fill until the arrow indicator goes dark, and click the lid shut.
When to call a technician Arrange a service visit if the message keeps coming back, or if the reservoir runs dry far too often even after you press the lid seal on firmly all round.

Do this

  1. Add rinse aid, and do not wait until the dispenser is empty.
  2. Press OK to confirm.

On the G 7000 / G 5000 models in Miele’s user manual the same shortage shows as “Refill rinse aid”, and what is left covers 2-3 programs. Open the reservoir with the yellow button on its lid. Fill until the arrow indicator goes dark, with the door held horizontal; the reservoir takes roughly 110 ml. Click the lid shut, since water can otherwise get in during a wash, and wipe off drips to prevent over-foaming.

A reservoir that runs dry far too often can mean the lid seal is loose or gone. Miele says to press it on firmly all round, or to find it inside the cabinet; a replacement is sold as a spare part.

If it keeps showing

The manual then points to Miele customer service. For a salt warning instead, read about F171, and for an electronic problem see F179.
