What E6002 means

The cycle drags or stops and E6002 appears. Unlike the neighboring numbers, this one has nothing to do with a heater part. Thermador documents E6002 as the heat pump being blocked, so water or air cannot pass through it freely, and the control halts instead of forcing the cycle along. That distinction matters, because it changes what a technician sets out to find and what the repair involves.

Usual causes of E6002

  • Debris or a physical obstruction restricting the heat pump
  • Mineral buildup, particularly where descaling has been put off
✓ A safe check worth trying

1. Switch the dishwasher's breaker off for half a minute. 2. Turn it back on and let the control restart. 3. Start a brief cycle and watch whether the code reappears. 4. Leave the panels alone, because reaching the heat pump takes disassembly. If E6002 returns, call us.

! Why you should stop here
  • Freeing a blocked heat pump generally calls for taking the machine apart, which exceeds a sensible home repair.
  • A restricted heat pump kept in service is under strain, and mineral deposits never dissolve by themselves.
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.

E6002E6002 questions
Would regular descaling have avoided this?

Perhaps. Mineral deposits are a plausible contributor, and that is one reason Thermador suggests descaling periodically, especially where the water is hard. The written price always comes before any work.

What separates E6002 from E6001?

E6001 names the heater inside the heat pump. E6002 describes the heat pump itself being obstructed, so the job is clearing it and not swapping a heater.

Can the blockage be cleared without a new pump?

Often it can. We clear it and retest the pump; if testing shows damage we say so, and the price is written down before any work starts.
