Why is my Siemens washing machine not draining?

Most likely causes

• 45% Blocked pump filter trapping debris, coins, or fabric fibres preventing water flow.
• 25% Kinked or crushed drain hose restricting water exit from the machine.
• 20% Faulty drain pump motor not spinning to expel water.
• 10% Failed pressure switch or control board not triggering the drain cycle.

How to diagnose it

1. 1

   Check the drain hose

   Inspect the hose at the back for kinks, twists, or cracks. Straighten any bends and ensure it's not compressed behind the machine.

   💡 The hose should have a gentle downward slope to the waste pipe.

2. 2

   Empty the pump filter

   Place a towel underneath, then locate the access panel at the front bottom. Turn the filter anticlockwise to unscrew and empty debris.

   💡 Siemens filters typically unscrew by hand—use a flathead screwdriver if very tight.

3. 3

   Run water through filter

   Rinse the filter under a tap to remove lint and fibres. Check the filter chamber opening for blockages and clean with a cloth.

   💡 Look for coins or broken plastic inside the chamber.

4. 4

   Test drain cycle

   Refit the filter, close the panel, and run a drain-only cycle (if available) or short wash. Listen for the pump motor humming.

   💡 No sound = pump failure; strange noises = internal blockage.

5. 5

   Check standpipe height

   Ensure your drain standpipe is not higher than 100cm. If too high, water cannot drain properly even with a working pump.

   💡 Measure from the floor to the top of the standpipe.
