Thermador Dishwasher E3000 and E:30-00: Water Protection Activated

What E3000 means

E:30-00 on a current E-generation model means the water protection system has been activated. The owner manual tells you to close the water supply valve and contact customer service. Treat it as a possible leak first. Thermador's website lists E3000 as a flow meter failure in the intake path, so the displayed meaning can differ by generation, and we confirm by model number.

Usual causes of E3000

Water collecting in the base tray, which activates the protection system
On older units, a flow meter that miscounts or an obstructed intake path

✓ A safe check worth trying

SAFETY FIRST. 1. Close the dishwasher's water supply valve. 2. Look for water on the floor or in the cabinet, and switch the breaker off if any reaches electrical parts. 3. Do not run cycles. 4. Wipe up water and call us. Never drag the machine over flooring, which strains the connections.

! Why you should stop here

The base tray and protection system sit under the unit, so tracing a leak means pulling it out.
Because the manual and website describe this number differently, ordering a part before the cause is verified risks the wrong one.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

E3000E3000 questions

Why do the manual and website differ?

The manual describes the water protection system for E:30-00, while the website describes a flow meter failure. The displayed meaning can differ by generation, so we confirm by model number and report what we find.

Should I close the water while waiting?

Yes. The manual says to close the water supply valve first, and we agree. Assume a leak until it has been ruled out, and leave the valve closed until we arrive.

Is it safe to run another cycle?

No. With protection activated, another cycle can add water to a base that may already hold some. Wait for the visit, and a photo of the display helps us prepare.
