Checking Filter System for Flow Restrictions
HBA HBA 12 & 14
Checking Filter System for Flow Restrictions
This diagnostic process helps determine if the installed water filter is impeding the normal flow rate of water to the dispensing components.
- No water flow at all when supply is confirmed on: Check for frozen pipes, closed shutoff valves, or complete blockage. Do not apply heat to suspected frozen plumbing near electrical components.
- If no water flow is detected despite confirmed supply, do not attempt to force flow; contact a qualified technician to check for internal blockages or supply line issues.
