1. Use a flat-head screwdriver to remove the lock screw from the top of the
brew actuator.
2. Tighten the locking nut with an allen key. Test tightness by moving the
actuator back and forth.
3. Adjust locking nut until desired tension is achieved.

Every 12-18 Months
Begin the 12-18 month preventative maintenance procedure by turning off
the machine’s white and red power switches, unplugging its power source,
disconnecting the main water line, and draining the steam.
After completing the following preventative maintenance tasks, reconnect the
machine to power and water, then turn on the red power switch only. Once
the machine has completely filled with water, turn on the white heating
element switch. Use machine only after it has heated fully.
Expansion Valve

After 12-18 months, the seal in the expansion valve will wear out, causing
water to leak from the valve. This will lead to temperature loss in the pre-
heat tank and premature failure of the water filtration system. To diagnose a
worn expansion valve, look for leaking water in the expansion valve drain
tube and listen for beeping from the Love Controller, which indicates a cold
pre-heat tank.
