Only use the new water supply hose shipped with your
▯
washer. Never use old used hoses.
The water supply hoses must not be kinked, bent, or
▯
pinched causing hose damage or restricting water
flow.
The water supply pressure must be between 14,5 to
▯
145 psi (1 - 10 bar) with a minimum of 2.2 U.S. gallons
(8 liters) of flow per minute. A pressure regulator valve
must be installed if the maximum water pressure is
exceeded.
Make sure the water supply faucet is easily accessible
▯
when the washer is in use. The faucet should be
turned off if the washer is going to be unused for
extended periods of time.
Make sure rubber washers are in place at both ends of
▯
the water supply hose. Missing washers could cause
leaks.
The connection points are under full water pressure.
