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
- Stop normal use and record E14 with the complete E-Nr and FD number for Thermador support. Do not pull out the dishwasher or open an inlet or flow-meter housing.
- Observe only for immediate external hazards such as spreading water, abnormal heat or an electrical smell. Keep clear of wet electrical areas and seek qualified help if any is present.
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 source names a flow-meter failure or a water-inflow/filling-system issue; E14 alone does not establish which part, if any, needs replacement.
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 the listed symptoms and source guidance against the model's service information before treating any part as failed.
