If it's the control panel or display that blanks out and reboots on its own, rather than the whole steam session stopping, this page covers that. Check the multipin connector on the power cable behind the cabin first, since a loose connection reads exactly like a reset, before assuming a part has failed. If the whole session cuts out and restarts rather than just the panel, see 'Why Does My Steam Shower Stop Mid Cycle' instead.

Quick diagnosis
If your steam shower is showing these symptoms:
- The control panel goes blank for a second, then comes back on its own
- The display reboots to its home screen without you touching anything
- It happens at a different point in the cycle each time
Likely causes, most likely first
- A loose or corroded multipin connector on the cable behind the cabin. This drops the connection to the panel and brings it back a moment later, which looks like a reset.
- The steam timer simply running out. Most panels stop the session automatically once the timer reaches zero, which can look like a fault if you expected it to keep running.
- A failing control panel or electronics box that reboots under load. More common on older units.
Likely cause
Check the connector behind the cabin first, rather than assuming a genuine component failure. A loose or damp multipin connector can drop the electrical feed to the panel for a moment and then reconnect, which reads exactly like a reset from the front. Where the reset happens at the same point in the cycle every time, it's worth ruling out the steam timer before treating it as a fault at all.
Check this first
- Check whether the reset always happens at roughly the same point in the cycle, which points to the timer rather than a fault
- With the power off, check the connection behind the cabin for looseness or visible moisture
- Note whether other functions like lights or the fan blank out at the same moment, which points to the connector rather than the panel on its own
How to identify your part
Check the connector first, rather than assuming a part needs replacing. If a new electronics box does turn out to be needed, match it to the model code on the panel … our MK117 electronics box fits MK117 panels, and our TR019 electronics fit TR019 panels; other model codes need their own matching box.
Parts that fix this problem
The following replacement parts usually fix this issue.

How to fix it
- Turn off the power and check the multipin connector on the cable behind the shower for looseness, corrosion or damp
- Reseat the connector firmly and dry off any moisture before restoring power
- Time how long the shower runs before it resets, and compare that to the timer setting on the panel
- If the connector checks out and the timer isn’t the explanation, the control panel or electronics box itself is the likely cause and will need replacing

When to call a professional
If checking the connector doesn't stop it, or you're not confident isolating the power safely, call a qualified electrician rather than keep testing it live.
