What E6002 Means
Thermador documents E6002 specifically as the heat pump being blocked, distinct from a heater-part problem.
Common Causes of E6002
- A physical blockage or debris restricting the heat pump
- Mineral build-up if descaling has been infrequent
🔧 One Safe Check You Can Try
Reset the breaker for 30 seconds, then restore power and check if the problem clears.
⚠ Why You Shouldn't Go Further Than That
- Clearing a heat pump blockage typically requires disassembly beyond a reasonable DIY step.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
