What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not repeatedly reset, tip, or move the appliance to clear a leak code.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- The safety switch detected water in the dishwasher base
- A leak, overflow, hose, seal, or water-path condition activated the leakage-protection system
Basic checks
- Observe only the floor and cabinet edge from a dry position after stopping the dishwasher; visible water means keep it off and do not touch the plug, outlet, appliance, or standing water.
- If the dishwasher water-supply valve is safely reachable without moving the appliance or crossing water, close it as Thermador directs; do not force a stiff, leaking, or corroded valve.
- Keep the door closed, photograph E15, and record the complete E-Nr for service; do not pull out, tilt, drain, or dismantle the dishwasher to search for the leak.
Reset or retry steps
- Do not reset or restart the dishwasher after E15; leak protection can remain necessary even if the display later clears or visible water dries.
- Leave the water supply closed and the dishwasher unused until Thermador or qualified service has identified and corrected the water source.
When to call a technician
- Contact Thermador support for every E15 occurrence because the official page identifies water in the base and an activated leakage-protection system.
- Seek urgent qualified help if water keeps spreading, reaches an electrical connection, or cannot be isolated safely from a dry location.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ
What does Thermador Dishwasher code E15 usually mean?
Thermador US documents E15 as water detected in the dishwasher base with leak protection activated. Model context matters: The Thermador US page says E15 follows water detected in the dishwasher base and activation of the leakage-protection system; drying the floor does not establish that the leak is resolved.
Can I keep using the dishwasher with code E15?
Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. Water below a dishwasher can reach live components; never touch the appliance, plug, outlet, or standing water from a wet position.
When should I call a technician for Thermador E15?
Contact Thermador support for every E15 occurrence because the official page identifies water in the base and an activated leakage-protection system. A qualified technician may check Leak-protection system and Dishwasher water path against the model's service information before treating any part as failed.
