- Power-reset the appliance once for at least 60 seconds.
- Check the basic user-accessible items linked to the fault such as filters, fitment, supply, or visible obstructions.
- Retest once and note exactly when the code returns.
The filter has reached the end of its lifespan. On the Toshiba TWP-TSR76THK(M), this code relates to the water purifier and should be interpreted together with how the appliance is behaving right now.
- The water purifier displays ALL_THREE_FILTER_LIFE_GRIDS_FLASH instead of normal status information.
- The current cycle, function, or startup sequence may stop, pause, or behave differently than expected.
- The same code may return after a reset if the underlying issue is still present.
- The water purifier detected The filter has reached the end of its lifespan.
- The underlying cause may involve sensors, controls, wiring, moving parts, or appliance-specific hardware.
- Record the full code, appliance model, and the stage of operation when the fault appears.
- Think back to recent cleaning, moving, installation, software, or electrical changes before the issue began.
- If the code returns after the basic checks, the next step is usually a proper service diagnosis.
- Do not keep forcing resets or repeated cycles if the same code returns immediately.
Book service if ALL_THREE_FILTER_LIFE_GRIDS_FLASH returns after one proper reset and the basic safe checks, because the water purifier likely needs model-specific diagnosis.
