Bertazzoni DW24PR Code Lsb: Rinse aid level low

What Lsb means

On Bertazzoni DW18PR and DW24PR legacy dishwashers, Lsb on the LED screen is not a breakdown. The Rinse Aid light is on and the screen shows Lsb to tell you that the rinse aid level is low. The remedy is simple: add rinse aid. The dishwasher will usually keep washing, but drying results may get worse until the dispenser is refilled.

Common causes of Lsb

Rinse aid dispenser is empty or nearly empty
Dispenser cap not closed fully after refilling
Rinse aid setting used up faster than expected
Level indicator not reading correctly

✓ One safe check you can try

1. Open the door and find the rinse aid dispenser, usually beside the detergent door. 2. Open its cap and pour in rinse aid up to the fill mark. 3. Wipe up any spill, since extra rinse aid can cause suds. 4. Close the cap firmly. 5. Run a cycle. If Lsb stays after refilling, call us.

! Why to stop there

Lsb is a refill reminder, so a visit is not needed until a refill fails to clear it.
Overfilling rinse aid causes streaks and foam.
The dispenser is part of the door, which should stay closed up.
If the light stays on after refilling, we test the level indicator and quote in writing first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

LsbLsb questions

Is Lsb a real error?

No. On the DW18PR and DW24PR it simply means the rinse aid level is low. Adding rinse aid is the fix, and the screen should clear after the next cycle.

What happens if I ignore Lsb?

The dishwasher still washes, but dishes may dry with spots and streaks. Rinse aid helps water sheet off, so it is best to refill soon.

Lsb stays on even after I refilled. Why?

The indicator may need a cycle to update, or the cap may not be closed. If it still shows after a full cycle, call us and we will check the level sensing.
