Siemens Washing Machine: not draining
What is this symptom?
Is your Siemens washing machine filling with water but failing to drain at the end of the cycle? This common issue may leave water sitting in the drum, often accompanied by error codes like E:18/F:18. Understanding the causes, such as a clogged filter or a kinked drain hose, can help you address the problem effectively.
Important Tips for Siemens Models
- Error code E:18/F:18 often indicates drainage fault related to pump/filter issues
Possible Causes
Clogged drain pump filter
How to Identify: Water remains after cycle, slow/no draining, debris visible in filter housing when accessed
Part: Drain pump filter
Kinked or obstructed drain hose
How to Identify: Hose bent, compressed, or positioned incorrectly beneath/behind machine; water won’t flow out
Part: Drain hose
Blockage in external plumbing (drain/trap)
How to Identify: Water backs up into washer, slow draining in other home fixtures suggests deeper plumbing clog
Part: Home drain/trap
Faulty drain pump motor
How to Identify: Unusual noises from pump, no humming sound, complete failure to drain after filter cleared
Part: Drain pump assembly
DIY Solutions
Clean the drain pump filter
- Turn off machine and unplug.
- Locate filter access (usually bottom front).
- Place towel/pan to catch water, slowly twist and remove filter.
- Clear debris and rinse filter.

Straighten or inspect drain hose
- Pull washer away from wall gently.
- Inspect drain hose for kinks, compression, or sharp bends.
- Straighten hose and ensure correct height/position per manual.

Check external drain/trap
- Disconnect hose from drain standpipe/cupboard.

- Use a plumber’s snake or similar to clear if safe and possible.

User Suggested Solutions
-
Check and clean the drain filter. Locate the filter access panel, usually at the bottom front of the machine. Open it, remove the filter, and clean it under running water. Ensure no debris is blocking the filter housing.
-
Inspect the drain pump for blockages or damage. Access the pump by removing the back panel. Check for any debris or foreign objects that may be obstructing the impeller. If the pump is damaged, it may need to be replaced.
-
Examine the drain hose for kinks or blockages. Ensure the hose is not bent or pinched, and detach it to check for any obstructions. If the hose is damaged, replace it with a new one.
