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.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- 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
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.
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.
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?
Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. 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.
