Frequently Asked Questions

What is Siemens Error E18?

E18 means the drain cycle did not complete within the expected time. Water remained in the drum — most commonly due to a blocked pump filter, kinked hose, or failed pump.

How do I manually drain a Siemens washer with E18?

Use the emergency drain hose in the filter access panel — a small capped tube. Remove the cap and drain water into a container. Then investigate and fix the cause.

Can a clogged drain hose cause E18 on Siemens?

Yes — accumulated fluff, coins, and fabric fibres can gradually narrow the hose or clog the pump filter. Regular filter cleaning prevents most E18 occurrences.
