What to do if BWT bestaqua 61 LT Water Filtration Systems show NO WATER ALARM?
- Y

  If the BWT Water Filtration System displays a 'NO WATER ALARM', it indicates a lack of water supply. This can be due to several reasons: * Closed shut-off valves or other obstructions at the inlet. Ensure the main stop valves are open and check the water supply. * Insufficient water supply pressure. Verify that the water supply pressure is between 3.0 to 6.0 bar. * A blocked pre-filter. If necessary, replace the pre-filter.

  Mary PetersonAug 22, 2025
  If your BWT Water Filtration System displays 'FAULT 7: HP FUSE BURNED', it usually indicates an issue with the pump. The possible causes include: * A defective pump. * A motor fault; check the operating parameters. * The pump being mechanically blocked or damaged. * The HP Pump fuse itself being burned. In any of these cases, replace the fuse.

Why does my BWT bestaqua 61 LT show CONDUCTIVITY is too high?
- D
  Derrick BrockAug 26, 2025
  If your BWT Water Filtration System displays 'FAULT 2: CONDUCTIVITY is too high', it means the conductivity level has exceeded the preset alarm limit. This can be due to: * Exceeding the preset alarm limit. In this case, increase the alarm limit value, or consider changing the module if that's not possible. * Fluctuating feed water quality. Increase the alarm limit value, or consider changing the module if that's not possible. * Defective RO membranes. Increase the alarm limit value, or consider changing the module if that's not possible.

What to do if BWT bestaqua 61 LT Water Filtration Systems show PEMEATE FLOW ALARM?
- K
  Kathryn SpenceAug 28, 2025
  If your BWT Water Filtration System shows 'FAULT 6: PEMEATE FLOW ALARM', it indicates that the permeate flow is outside the acceptable range. This can happen if the preset alarm limit has been exceeded, so increase the alarm limit value. Alternatively, the membranes might need replacement.
