Connection to a water tank using a pump

For locations without a permanent water supply, the Milkshaker S can run from a water tank using a submersible pump. This guide covers the full setup: pump connection, initial water pumping, water level adjustment, and final water output verification.

Connection procedure

  • Take the pump and hose out of the shipping packaging: photo.
  • Pump and hose unboxed
  • Connect the cable connector and hose to the matching connectors on the back panel of the machine.
  • Pump cable + hose connectors on back panel
  • Lower the pump to the bottom of the water tank.
  • Pump submerged in water tank
  • Set the water supply switch to the down position.
  • Water supply switch in lower position
  • Turn the taps to the position shown on the picture.
  • Tap positions for water-tank supply
  • Power on the machine and wait for the software to load. On first start, “Error 1 No Water” will appear — this is expected.
  • Press SERVICE MODE and tap “Water pumping”. Place a container under the dispensing window.
  • SERVICE MODE
  • The machine fills the hydraulic line. Water flows through mixer #1 into the dispensing window. Wait for the cycle to complete.

Adjusting the water level

Run a pumping cycle and check the water level in the mixer funnel. Optimal level is the green line; red marks too low or too high:

  • If the level is off, adjust the pump voltage with a small flathead screwdriver. The adjustment is made by turning the right adjustment screw on the back panel during a pumping cycle: photo.

  • To increase flow, turn the right screw clockwise; to decrease, counterclockwise. Re-check the funnel level. Repeat until correct.
  • Open the service menu and rinse mixers using buttons 1 and 2 on the screen.
  • buttons 1 and 2
  • Press CONTROLLER REBOOT. After restart, confirm “Error 1 No Water” no longer appears.
  • CONTROLLER REBOOT

Water output verification

After the level is correct, verify water output in the service menu’s “Calibration value” tab. Without this step, drink dosing can be off by 10–20%.

The water supply connection setup is complete.

Connecting the water bottle

Important — pump placement: Always keep the water pump at the very bottom of the water bottle, fully submerged. Running the pump dry (without water) overheats and burns out the motor.
