Miele Dishwasher Inlet/drain light flashing — What It Means & How to Fix It

Also shown as Intake/drain indicator flashing on some models.

By Callum Griffin · Researched and verified against manufacturer and repair documentation · Reviewed September 2026

When the inlet/drain light flashes, the dishwasher saw a problem supplying or removing water — and Miele's own checklist covers the faucet, the inlet filter and the hose.

What this code means

On newer Miele dishwashers the classic number codes give way to indicator lights, and the flashing inlet/drain light is the family flag. Miele USA's support page is refreshingly direct: a fault occurred while water was being supplied or drained, and the first suspects are the faucet being off, the inlet filter being soiled, or the water inlet hose being kinked. If those three check out clean, the fault has moved into the machine — inlet valve, flow meter, or the drain side — and a technician earns their fee.

Documented by Miele USA for newer G-series dishwashers as a flashing inlet/drain indicator; on earlier G 1xxx–G 6xxx machines the same faults appear as F11/F12/F13 numbers.

Most likely causes

CauseHow likelyDIY-fixable?
Faucet (stopcock) not open Common Yes — turn it on
Inlet filter soiled with grit or scale Very common Yes — clean under running water
Water inlet hose kinked Occasional Yes — straighten it
Drain side problem — blockage or kinked drain hose Occasional Limited — inspect and clear

What you can try yourself

  1. Unplug the dishwasher, then confirm the faucet under the sink is fully open.
  2. Close the faucet, unscrew the water-intake valve, and pull out the plastic filter bar to rinse clean — never dip the valve housing in water.
  3. Refit the filter and seal, tighten the connection, and slowly reopen the faucet, watching for drips.
  4. Straighten any kinks or loops in the inlet hose, and check the drain hose behind the machine for the same problem.
  5. Plug back in and run a short program; if the light still flashes after all three checks, the fault is inside the machine.

When to call a technician

Typical professional repair cost: Free for the faucet, filter and hose checks; about $150–400 if it lands on a pump or valve repair.

Frequently asked questions

My model has no numbers, just lights — how do I know if this is intake or drain?

You usually can't tell from the light alone. Do the intake checks (faucet, filter, hose) first because they're the most common, then check the drain hose — the machine will tell you by which way water fails.

The light flashed right after a power cut — is something broken?

Not necessarily. A transient blip can set the fault. Let the machine complete a reset cycle with the faucet open, and only investigate if the light returns.
