What F - WATER DRAINAGE FAULT means

Drain is blocked or restricted, or the drain hose is installed too high. On the Miele PWM 511, this code relates to the washing machine and should be interpreted together with how the appliance is behaving right now.

Common symptoms

  • The washing machine displays F - WATER DRAINAGE FAULT instead of normal status information.
  • The current cycle, function, or startup sequence may stop, pause, or behave differently than expected.
  • The same code may return after a reset if the underlying issue is still present.

Most likely causes

  • Drain filter, sump, or outlet path is blocked.
  • Drain hose is kinked, crushed, or blocked, or the pump cannot clear the water properly.

Deeper checks before service

  1. Check whether the fault started after installation or after reconnecting the drain line.
  2. Make sure the waste connection is open and routed correctly.
  3. If the code returns after clearing the drain path, the pump or related control circuit may need service.

Safety warnings

  • Isolate power before reaching into pump or filter areas.

When to contact support

Book service if F - WATER DRAINAGE FAULT returns after cleaning the drain path, or if the pump sounds abnormal and the washing machine still cannot empty correctly.

FAQ

Can F - WATER DRAINAGE FAULT clear after a reset?
Sometimes a temporary glitch clears after one full reset, but a repeated return usually means the same underlying issue is still there.
