Soda Solenoid Valve Replacement - Lavit LB115 Series Troubleshooting Manual

If the soda valve is continually dripping it may be due to a piece of sediment trapped on the
plunger seal of the valve and stopping it from sealing shut. To confirm the soda valve is
dripping, first vend a still water, then turn off the water supply to the machine, then power
down the machine, and make sure the C02 regulator is turned on. If the soda water is
continually dripping for a minute then it is not sealing correctly.
1)
The soda valve is mounted on the left-hand side of the
brewer and is the valve nearest to front (the front
valve)
2)
The valve needs to be stripped to gain access to the plunger
seal where there may be a piece of sediment.
3)
To do this you need to remove the valve and do the following.
4)
Power down, turn off the water supply, turn off the C02
regulator, and release the pressure in the soda tank by
actuating the purge valve mounted on the rear of the
machine.
5)
Remove the top cover. 2 screws at the back and 2 screws
on the side wall of the brewer. Disconnect the LCD and the
push button cable plugs
6)
Remove the left-hand side panel, release the 3 screws at
the base, 1 screw on inside of panel near the brewer, two
screws on the rear panel, and a push clip on the rounded
front part of the panel.
7)
The solenoid is held in place by 2 screws from base.

8) To gain access to the 2
screws you need to loosen
the 4-screws holding t he
brewer and tilt it on its side gently.
9) Undo the solenoid.
10) Purge the C02 again before you remove the
soda water line. This line is pressurized so always turn
off C02 and purge before disconnection. The line will
drip as the soda water expand.
11) Remove the solenoid enough to gain access to
the base.
12) On the underside in two recessed holes are two
small retaining screws that hold the valve bonnet in
place.
