What E2030 means

Dishes finish a cycle wetter or cooler than they should, and E2030 is showing. Thermador documents this code as a problem with the heat pump's internal heater. The control is told whether that heater is warming as expected, and E2030 appears when what it measures does not match what it commanded. You may notice it first as damp dishes or a cycle that never seems to warm up.

Usual causes of E2030

  • A failed internal heater part inside the heat pump
✓ A safe check worth trying

1. Switch off the dishwasher's breaker. 2. Wait for thirty seconds. 3. Turn the breaker back on and wait for the display to wake up. 4. Run a short cycle and watch for the code. If it comes back, do not keep repeating this and call us instead.

! Why you should stop here
  • The heat pump's internal heater is not something a homeowner can reach or test.
  • Continuing to run weak-heating cycles leaves dishes wet while the cause stays unfixed.
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.

E2030E2030 questions
Will dishes dry worse because of E2030?

Probably. Weak heat pump heating usually means damp dishes in addition to the displayed code. Tell us the model number so the visit starts well.

Is E2030 the same as E6001?

Thermador words the two identically: the internal heater of the heat pump. The control generation of your model decides which number appears, and the repair starts in the same place.

Can I hand-dry and keep using the machine?

You can for a short time, but heating performance is only going to get worse. It is better to schedule a visit before a minor part problem spreads to other parts.
