What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
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.
Applicability
Regional guidance · Thermador dishwashers covered by the United States support library · United States · Official US dishwasher error-code support library
This meaning comes from the Thermador United States dishwasher support library; confirm the exact E-Nr owner manual because available codes, controls, and owner-safe actions can differ by model and market.
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.
Can I keep using it?
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.
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- 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 continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- 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
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?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. 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.
