Help - Miele dishwasher showing an E code and won't drain

If it’s leaving water in the base, the fault is usually somewhere in the drain path rather than the control itself. On Miele dishwashers an “E” code can mean different things depending on the exact model, so the best approach is to narrow down whether the machine is actually unable to pump out.

1. First, switch it off, isolate it from the mains, and bail out as much water as you can from the bottom. 2. Remove and clean the filters thoroughly. Check the sump area underneath for debris such as glass, labels, bones or grease build-up. 3. Look at the drain pump impeller if accessible under the filter area. Make sure it isn’t jammed and can move freely. Even a small bit of debris can stop it draining. 4. Check the drain hose for kinks, crushing or a blockage. If it goes into a sink trap, remove the spigot connection and make sure the trap isn’t blocked with sludge. 5. If it drains into a standpipe, check the hose hasn’t been pushed too far down or restricted. 6. Run a drain/reset programme and listen: if the pump hums but no water moves, suspect a blockage or weak pump. If it’s completely silent, there may be a pump, wiring or control issue. 7. Also check the anti-flood base tray if your model has one. If water has leaked into the base, a float switch can stop normal operation and bring up a fault.

If you can post the full error code and exact Miele model number, it may be possible to be more specific. For any internal electrical checks, or if the pump needs testing/replacing, use a qualified appliance engineer.
