Steam shower panels use touch-sensitive electronics, and moisture behind the panel is usually the reason one starts triggering on its own. Drying the panel out and cycling the power usually clears it. If it keeps happening afterwards, the panel's seal has likely failed and water is reaching the circuit board underneath.
Applies to: steam showers
If your steam shower is turning on by itself, it can seem like a serious fault — but in most cases, it’s a known issue caused by moisture affecting the control panel rather than a failure of the system.
This behaviour is commonly referred to as “ghosting,” where the panel registers false inputs without being touched.

Quick diagnosis
If your steam shower is showing these symptoms:
- Lights, fan or steam start up without anyone touching the panel
- Buttons seem to press themselves, sometimes repeatedly
- The panel behaves oddly after a shower or in a steamy bathroom
- The problem comes and goes rather than staying constant
- The panel still shows a normal display when it happens
Likely causes, most likely first
- Moisture behind the panel. Condensation settling on the circuit board can read as a finger press, known as “ghosting.” Worse in bathrooms with poor airflow or where the cabin is left shut straight after use.
- Protective film left on the panel. The clear film some panels ship with can trap moisture against the touch surface, making ghosting more likely rather than less.
- A failed panel seal. If drying and airing the panel doesn’t stop it, water is probably getting in properly rather than just condensing on the surface, and the seal behind the panel needs attention.
Likely cause
Usually this comes down to condensation on the panel's circuit board rather than anything electrically wrong with the unit. Steam shower panels use touch-sensitive electronics that can misread a build-up of moisture as a genuine button press. It's more likely where the bathroom has limited ventilation or the cabin door is kept closed after every use, letting humidity linger against the panel.
Check this first
- Check whether the protective film is still on the panel and peel it off if so.
- Leave the cabin door open after each use rather than shut, so steam can clear instead of settling on the panel.
- Note whether it only happens in humid weather or straight after a shower, which points to moisture rather than a wiring fault.
How to fix it
- Turn off the power at the isolator or RCD before touching the panel
- Dry the panel gently with a hairdryer on a low heat setting, working around the edges first
- Check the protective film has been fully removed from the panel face
- Leave the power off for five minutes, then switch back on
- Leave the cabin door open after use so humidity doesn’t build up against the panel
- If it still happens once the panel is dry, turn off the power and get the seal checked before using it again

When to call a professional
Call a qualified electrician if the panel is wet to the touch, if you can see water inside the housing, or if drying it out doesn't stop the problem after a couple of uses.
