Krupps SAL

What does Krupps SAL mean?

SAL on a Krupps dishwasher means the brine is exhausted: there is not enough brine (water and salt solution) for the resins regeneration of the built-in water softener. The softener can no longer regenerate, so the operator needs to add softener salt. This is a user-serviceable warning rather than a hardware fault.

Symptoms

• 'SAL' message shown on the display
• Salt level low in the softener container inside the tank
• Water softener no longer regenerating
• Possible increase in limescale / poorer rinse results over time

Common causes

• Salt used up in the built-in water softener
• Salt container inside the tank not refilled
• Brine (water and salt solution) insufficient for resin regeneration

Diagnostic steps

1. 01

   Refill softener salt

   User action: refill salt inside the container (with cap) inside the tank. The manual recommends using special softener salt.

2. 02

   Use the correct salt

   Use proper water-softener salt as the manual recommends, not table salt, so the resins regenerate correctly.

3. 03

   Allow the warning to clear

   After refilling, the warning clears once the brine is replenished; on first fill the salt may take time to dissolve before the message disappears.

4. 04

   Technician: recover the brine if needed

   Technician check: recover the brine inside the built-in softener if the SAL message persists after refilling.

When to call a professional

SAL is normally a user task — simply refill softener salt in the capped container inside the tank. Call a technician only if the message persists after correctly refilling with proper softener salt, in which case the manual's technician check is to recover the brine inside the built-in softener. A lingering SAL after a correct refill suggests the softener's regeneration system itself needs service.
