E7 error and the display shows abnormal salt level or brine tank alarm

Safety: Unplug the unit and wear gloves when working inside the brine tank. Avoid breathing salt dust.

• Check actual salt level: Open the brine tank lid and visually confirm the salt level. If the tank is nearly empty, refill with the recommended Tapworks tablet salt and reset the alarm if applicable.
• Break salt bridges: Use a broom handle or plastic rod to gently push down through the salt. If you feel a hollow space beneath a hard crust, you have a salt bridge. Break it up carefully so salt falls into the water below.
• Inspect the sensor: Locate the brine/salt level sensor (float or electronic probe). Ensure it moves freely and is not buried in hardened salt. Clean off any salt crust with warm water and a soft brush.
• Check wiring: Trace the sensor cable to the control board and ensure it is firmly connected and undamaged.
• Reposition if necessary: Confirm the sensor is mounted at the correct height as per the Tapworks installation guide. Adjust if it was installed too high or too low.
• If E7 remains after cleaning and wiring checks: Replace the Tapworks brine level sensor assembly.
