What 5 Means
Thermador documents the "5" indicator as simply meaning there's no water-softening salt in the dishwasher — not an error.
Common Causes of 5
- Normal salt depletion over repeated cycles
🔧 One Safe Check You Can Try
Refill the softening salt compartment per your manual's instructions.
⚠ Why You Shouldn't Go Further Than That
- This is routine maintenance, not a repair issue.
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.
