E1 — Steam component fault (steam models)

How to fix it

1. Refill the steam reservoir with tap water (not distilled, not softened) to the MAX line.
2. If plumbed to a water line, confirm the supply valve is open and the inlet screen at the dryer is clean.
3. Run a Steam Fresh cycle and watch/listen for valve operation.
4. Unplug and access the steam valve; test the solenoid for continuity per service manual and replace if open.
5. Inspect and descale the steam generator; replace if heavily scaled or burned out.
6. If E1 persists with known-good components, replace the main control board.

Why it happens

Typical signs: E1 on display when starting a Steam cycle · No steam produced during Steam Fresh/Refresh cycle · Normal cycles work fine · Water reservoir empties without effect

• Steam reservoir empty Steam Fresh tank not filled to MAX with tap water.
• Clogged water inlet screen Mineral buildup blocks supply to the steam generator.
• Steam heater / generator failed Element open, calcium scaled, or sensor open.
