Float Switches
The float switch is wired in the circuit between the timer and the water iniel valve. The purpose of the float switch
is to prevent an overflow in the event the drain system shoitld fall or the timer should stick in the fill position allowing
too much water to enter the tub 11 will not prevent an overflow should the water inlet valve develop a mechanical
defect
The swiich is operaied bv a hoai lonaied m the suh ^Fiqurp 66) whirh rises with the water level At s predeter
mined level, before an overflow can occur, the float opens the switch contacts and breaks the circuit to the
water inlet valve
The swftch is 3 normaity operi micro switch which is held closed by the weight of the float
The float switch may be checked by placing the leads from an ohmmeter across the switch terminals Raising and
lowering the float should cause the switch contacts to dose or open the circuit
NOTE:
Almost every dishwasher on ihe market has a timed ftfi period Some have a pressure switch for overflow pro­
tection. others havea float switch Normally an inlet valve should remain open for 45 ю 90 seconds. There are,
however, instances where a machine will fill so rapidly ¡because of high water pressure] that the overflow
switch will cut off the inlet valve to prevent an overflow. This will result in a pause between fill valve cut off
and the start of the wash or rinse cycle This is normal and no adjustment should be made
