CRITICAL COMPONENTS TESTS
WARNING
: Brewer should be unplugged from
electrical outlet before any service is performed.
A) Water Inlet Valve Test
Check hot water side, going to tank:
1. Turn power off. If the water level rises inside the
tank, the Water Inlet Valve is leaking.
2. Disconnect wires from the Water Inlet Valve coil and
connect a 2 wire line cord to the terminals. Plug it
into electrical outlet. If water flows in and stops
when you pull it out, the Valve is working correctly.
Repeat this test a few times. The problem may be in
the Probe or Water Level Control Board. If water
does not flow in when the cord is plugged into an
electrical outlet, the Solenoid coil may be damaged,
opened, or the valve may have an obstruction
preventing the water from flowing in. Clean or
replace it.
Check cold water side, going to dilution nozzle:
1. Turn power off. If water keeps coming out of the
dilution nozzle, the solenoid might be clogged or
damaged.
2. Check Valve should be provided and installed by the
customer to prevent backflow. To check proper
function of Check Valve, disconnect water line from
the Check Valve, check for dripping from the
disconnected end of the Check Valve. If it leaks
replace it.
