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
- Inspect only the visible, accessible supply hose without pulling out the dishwasher or loosening a connection; a kink, crush point, damage, or water means keep the appliance off for qualified review.
- From a dry position, note whether the household water valve appears open and whether nearby cold-water fixtures have normal flow; do not force a stiff or leaking valve.
- Record E14 and the complete E-Nr so Thermador support can identify the applicable model guidance; the official page does not authorize owner access to the flow meter or filling system.
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
- The official E14 guidance directs the owner to Thermador support and does not provide an owner reset or test cycle.
- Do not restart the dishwasher, disconnect a hose, open an inlet housing, or attempt to clear E14 by repeatedly operating the water valve.
When to call a technician
- Contact Thermador support whenever E14 appears because the documented flow-meter or filling-system condition requires model-specific diagnosis.
- Use a plumber for a leaking or failed household valve and qualified appliance service for the dishwasher-side inlet, sensor, wiring, or control path.
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.
- Disconnect power before any service-access step.
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 disconnect inlet hoses until the water supply is off.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- The dishwasher is not receiving the expected water-flow signal
- A flow-meter, filling-system, inlet, sensing, or control condition requires qualified diagnosis
FAQ
What does Thermador Dishwasher code E14 usually mean?
Thermador US documents E14 as a flow-meter failure or a dishwasher water-fill system issue. Model context matters: The Thermador US page presents E14 as either a flow-meter failure or an issue with water entering the dishwasher or filling system; it does not confirm one failed part.
Can I keep using the dishwasher with code E14?
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. Do not disconnect a hose, pull out a built-in dishwasher, open a panel, or probe the flow-meter circuit; water can reach live parts.
When should I call a technician for Thermador E14?
Contact Thermador support whenever E14 appears because the documented flow-meter or filling-system condition requires model-specific diagnosis. A qualified technician may check Flow-meter system and Water-fill system against the model's service information before treating any part as failed.
