Miele Washer F10 — What It Means & How to Fix It
F10 means the washer isn't getting enough water — closed stopcock, blocked inlet filter or a faulty inlet valve — and the first fixes are all done at the plumbing, not in the machine.
What this code means
F10 is Miele's water-intake fault: the machine isn't filling properly. Domex's engineer's list puts the causes in order — a closed stopcock, a blocked inlet filter, or a faulty inlet valve — and Miele USA's own 'water inlet fault' page adds the supply-side truth: if the water pressure in the line is too low, no machine will fill correctly. The owner checklist is entirely at the plumbing: open the stopcock, clean the mesh filter in the inlet hose connection, straighten the hose. If the machine still won't fill, the inlet valve or flow path needs a technician.
Listed for Miele washers by Domex (F10 water intake); Miele USA's 'water inlet fault' support page covers the same intake problem for washers, citing low line pressure as a cause.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Stopcock under the sink is shut or partly shut | Common | Yes — open it fully |
| Mesh filter in the inlet hose connection is blocked | Common | Yes — clean it |
| Inlet hose kinked or low household water pressure | Occasional | Yes — straighten; low pressure needs a plumber |
| Inlet valve or flow meter failed | Less common | No — technician job |
What you can try yourself
- Turn the machine off, then check the stopcock at the water supply is fully open.
- Turn the water off at the stopcock, unscrew the inlet hose at the machine end, and clean the small mesh filter inside the connection under running water.
- Reconnect the hose firmly, reopen the stopcock slowly, and check the connection for drips.
- Straighten any kinks in the inlet hose and confirm other taps in the house have decent pressure.
- Run a short rinse cycle; if F10 still appears with a clean, open supply, the inlet valve needs a technician.
Seeing the symptom rather than the code? Washer not filling: checks that apply across brands.
When to call a technician
- The connection weeps after you retighten it — close the stopcock.
- Very low water pressure throughout the house — check with a plumber before blaming the machine.
- F10 returns even with the stopcock open and filter clean.
Typical professional repair cost: Free for the stopcock, filter and hose checks; around $150–300 if the inlet valve needs replacing.
Frequently asked questions
Can low water pressure really cause F10?
Yes — Miele's own page says a 'water inlet fault' can be caused by line pressure that's simply too low for the machine to fill in time. That's a supply problem, not a washer problem.
I cleaned the filter but F10 came back weeks later — same filter?
Likely the same cause — grit from the supply can re-clog a filter quickly. If it keeps recurring every few weeks, consider having the supply checked and the inlet valve inspected.
