    How to fix low water pressure in Cornelius Beverage Dispenser?
    • P
      paigewigginsAug 28, 2025
      Low water pressure in your Cornelius Beverage Dispenser could be due to excessively long runs (over 40 ft.) of 3/8” water supply line, so increase the line size to 1/2”. Alternatively, it could simply be low water pressure, in which case you should add a water pressure booster pump. A plugged water filter can also cause this issue, so try changing the water filter. Finally, the water booster bladder may have burst, requiring you to replace the water booster tank/bladder.

      Continuous ice dispensing from your Cornelius Beverage Dispenser may be caused by the ice gate mechanism being stuck in the open position. Inspect the gasket for proper position and examine the gate plate to see if it slides freely behind the lower ice chute. Another cause could be a stuck or bent ice lever, which prevents the gate from closing and opening the reed switch. Examine the ice dispense lever to see if it is bent.
