Miele Dishwasher Error F14 – Causes & Fix
The wash pump didn't build enough pressure, so the heater stays off. Miele's warm-water fix often works.

A Miele dishwasher only switches its heater on once a pressure switch confirms that the circulation pump is moving water with enough force; that protects the heater from running dry. F14 means the switch never saw that pressure. The usual reasons are an air pocket in the pump, a clogged filter combination that starves it, foam, or a pressure switch chamber gummed up with grease and scale. Miele's own first fix is to pour warm water with a few drops of rinse aid into the machine, let it stand and restart, which frees trapped air and loosens deposits. Most reports come from the older G 1000 and G 2000 generations; on other generations, check the fault list in your manual.
How it looks on the display
Model families & display variants
| Model family | Shows | Note |
|---|---|---|
| Models with a numeric display | F14 | Sometimes written F 14. Most reports are from the G 1000 and G 2000 series. |
| Models with a text display | Fault F14 | The text display names the fault and may add a hint to contact Miele service. |
| Older models without a display | blinking lights | Faults are shown with indicator lights; the fault table in the operating instructions explains the pattern. |
Safety first · Consult a professional
Switch the dishwasher off before taking out the spray arm and filters. Use warm water, not boiling: Miele's guidance tops out around 165°F.
- Unplug the appliance or switch off the breaker before opening any panel. Mains voltage can kill.
- Hot surfaces and hot water can cause burns. Let the appliance cool down first.
Symptoms
- F14 on the display, often early in the program
- Dishes come out cold or poorly washed
- Pump sounds uneven, rattles or slurps as if drawing air
- Code appeared after the machine was unused for weeks
- Code appeared right after a drain fault or filter cleaning
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Air trapped in the circulation pump
- Filter combination clogged, pump starved of water
- Pressure switch chamber or hose blocked by grease and scale
- Circulation pump weak or blocked by debris
- Foam from dish soap or too much detergent
- Pressure switch or control electronics faulty
Fix it step by step
Do Miele's warm-water routine
With the spray arm and filters out, pour about 1 quart of warm water with a few drops of rinse aid into the sump, wait 5 minutes, reassemble and restart. Repeat up to three times.
Tools: Towels & shallow pan
Clean the filter combination thoroughly
Separate the coarse filter, the microfine filter and the flat filter and clean each with a soft brush and warm soapy water. A greasy flat filter restricts flow enough to trip the pressure check.
Tools: Soft brush, Gloves
Look for foam
If there's foam in the tub, wipe it out and run a rinse with plain water. Only automatic dishwasher detergent belongs in a Miele.
Tools: Towels & shallow pan
Check the pump opening
With the filters out, shine a light into the sump and remove glass, pits or labels near the pump intake. Don't push anything into the pump itself.
Tools: Flashlight, Gloves
Leave the rest to Miele service
If F14 keeps coming back, the pressure switch, its hose or the circulation pump needs to be checked from below. On many models that means removing the unit from its cabinet, which is a job for Miele service or an experienced technician.
How to reset F14
- Switch the dishwasher off with the On/Off button.
- If the code persists, disconnect power at the breaker for a few minutes.
- Switch on and restart the program; F14 should not return once the pump builds pressure.

When to call a technician
Call Miele service if F14 returns after three rounds of the warm-water routine, clean filters and no foam. From there it's a pressure switch, pump or electronics diagnosis that usually requires pulling the unit out.
Frequently asked questions
Why does rinse aid help with F14?
Rinse aid lowers the surface tension of the water, which helps trapped air escape from the pump and lets the water wet greasy surfaces again. That's why Miele suggests it as the first step.
How is F14 different from F11?
F11 is a drain problem: water can't get out of the machine. F14 is a circulation problem: the pump can't build pressure to spray the water and allow heating.
Can I keep using the dishwasher with F14?
The program stops or runs without heating, so dishes won't be properly cleaned. Try the warm-water routine; if the code stays, wash by hand until the machine is repaired.
Is F14 common on newer Miele models?
Most reports come from the G 1000 and G 2000 generations. Fault lists differ between generations, so check the table in your operating instructions to confirm what F14 means on your model.
