Miele Dishwasher Error Code F55: Meaning and Fix
Also shown as: Waterstop
Reading the dishwasher display
A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Miele displays an F followed by a number and often a text hint in your language.
Miele reports faults as F-numbers on dishwashers and washers and expects many of them to be handled by a service technician. Plenty of the entries here are first checks you can safely do before booking a visit. The codes apply to model numbers such as G 4228 SCU, G 7156 SCVi and W1 Classic WWF060; check the label on your unit to confirm yours.
What causes F55
- Water collecting in the base from a leaking door gasket, hose clamp or spray-arm seal
- A float switch or leak sensor stuck or tripped by residual water
- Float switch caught in the up position by debris
- Overfilling caused by a faulty inlet valve or too much detergent/foam
How to fix it
- Unplug the appliance and shut off the water supply before you investigate.
- Pull the unit out (or remove the toe-kick) and look for wet spots, damp insulation and drips under every hose connection.
- Clean the area around the float and make sure it moves freely.
- Soak up any water in the base pan, then wipe the float and sensor area clean so they move freely.
- Replace worn gaskets, tighten or replace hose clamps and use only the recommended amount of low-sudsing detergent.
- Restore power, run a short test cycle and dry-check the floor and pan afterwards.

Questions
What does error F55 mean on a Miele dishwasher?
The leak protection system detected water in the base or hose and shut the water supply. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my dishwasher while F55 is showing?
No. Leave the water supply off until the leak is traced, to avoid floor and cabinet damage.
How do I clear F55, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
