The steam valve part of the water valve assembly 
is a low fl ow water valve used during steam cycles. 
Steam is created by heating a small amount of 
water in the sump.
The fl ow meter is built into the water valve assem-
bly and cannot be replaced separately. It is used to 
monitor fi ll rate and keep a cumulative count of the 
amount of water that has entered the washer. The 
fl ow meter consists of a hall senor and water paddle 
that has 2 embedded magnets. Water fl ow causes 
the paddle to rotate. As the paddle rotates, the 
magnets of the paddle interact with the hall senor 
which generates a pulse train to the IMC board.
