What to do if my AL-KO HWA 4000 comfort Water Pump shows 'ALARM CHECK PRE 1.5 BAR'?
- C
  Charles TuckerAug 4, 2025
  The 'ALARM CHECK PRE 1.5 BAR' message indicates that the AL-KO Water Pump has switched off as a protection against overheating. This is often due to a fault on the pressure side, such as a leak. Even small leaks on water taps and toilets can cause the system pressure to drop. You should check the pressure line and draw-off points for leaks. Also, check and clean the check valve in the filter chamber. After rectifying the fault, confirm with SET to restart the pump. Be aware of potential hot water when the restart occurs.

What to do if AL-KO HWA 4000 comfort Water Pump displays 'CHECK SUCTION SI 0.0 BAR'?
- M
  Melvin LaneAug 26, 2025
  The message 'CHECK SUCTION SI 0.0 BAR' appears for 20 seconds. The AL-KO Water Pump will attempt to rectify the fault itself for 90 seconds. No action is required from you during this time. However, if the fault persists after 90 seconds, the pump will switch off as a dry-run protection.
