Miele dishwasher F11 error and standing water
Miele G5210 SC throws an F11 (drainage) fault near the end of the cycle with water pooling at the base. Cleaned the filter and checked the drain hose for kinks behind the unit. What else causes F11 — the drain pump or the non-return valve?

Miele G5210 SC shows F11 drainage fault with water left in base
- The problem
- A Miele G5210 SC dishwasher reports F11 near the end of the cycle and leaves standing water in the base. The filter had been cleaned and the drain hose checked for kinks.
- Likely cause
- The accepted reply says F11 indicates a drain problem but does not by itself confirm a failed pump. The most strongly supported causes mentioned are a blockage or restriction in the sump or drain path, debris jamming the drain pump impeller, a weak or damaged drain pump, or a blocked, stuck or distorted non-return valve. A blocked sink trap/standpipe connection was also highlighted as common.
- What fixed it
- Recommended action was to isolate the appliance from the mains, then re-check the sump area for debris, inspect the drain pump impeller for free movement or damage, inspect the non-return valve for blockage or damage, and check the drain path including the sink trap/standpipe spigot. If these checks do not resolve it, further diagnosis of the drain pump circuit should be carried out by a suitably qualified appliance engineer. The thread was marked solved, but no completed repair or confirmed fix was posted.
- Checks to try
- Filter cleaned
- Drain hose checked for kinks
- Inspect sump area for debris
- Inspect drain pump impeller for jamming or damage
- Inspect non-return valve for blockage or distortion
- Check sink trap/standpipe spigot for blockage
- Listen to pump during drain
Safety: Isolate the dishwasher from the mains before internal checks. Further diagnosis should be carried out by a suitably qualified appliance engineer.

F11 on a Miele usually points to a drain problem, but it does not automatically mean the pump itself has failed. If there is still standing water, the fault is more often a restriction, a weak pump, or an issue around the non-return valve.
Before checking anything internal, isolate the dishwasher from the mains.
1. Check the sump area thoroughly Remove the filters again and inspect the sump beneath for debris such as glass, labels, grease build-up or food sludge. Even a partial blockage can slow draining enough to trigger F11 near the end of the cycle.
2. Inspect the drain pump impeller On many Miele dishwashers you can access the pump cover from inside the tub. Check whether the impeller turns freely and is not jammed by broken glass or bone fragments. If it is stiff, damaged or loose on the shaft, the pump may be faulty.
3. Check the non-return valve Yes, this can cause the symptom. If the valve is stuck, distorted or clogged, water may not discharge properly or can run back into the base after pumping out. Remove it if accessible and check for debris and damage.
4. Check the drain path beyond the hose Look at the spigot on the sink trap/standpipe connection. A blocked sink trap spigot is very common, especially if the hose itself seems clear.
5. Listen during drain If the pump hums but water leaves slowly, suspect a blockage or weak pump. If it is silent, the pump, wiring or control side needs testing.
If the simple checks do not sort it, the next step is proper electrical testing of the drain pump circuit. For any mains electrical work, use a qualified appliance engineer.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
