The water level switch is adjusted at
the manufacturing source and
no
adjustments should be made in the
field.
Whenever the hose is removed from the
water level switch or the air bell nipple,
DO NOT reconnect the hose until all
water has been drained from the tub. To
assure proper operation of the water
level switch, the hose must not have any
water in it when reinstalled on the switch.
When reconnecting the hose, be sure to
slip it over the nipple(s) as far as possible
and always replace the hose clamp(s).
WATER LEVEL SWITCH
OPERATION
The water level switch used on the Elec-
tronic Control Washer consists of the
following internal switches:
.. Low - Contacts 11-14, normally open.
.. Super - Contacts 21-24, normally open.
.. Overflow - Contacts 31-32, normally
closed.
These switches are used in conjunction
with the electronic control to provide all
the featured water level settings. These
settings are accomplished as follows:
.. low Setting - Contacts 11-14 close .
.. Medium Setting - Contacts 11-14 close
and the electronic control calculates
additional time for the mixing valve
circuit to stay closed.
.. High Setting - Contacts 11-14 close
and the electronic control
calculates
still more additional time
for the m ix-
ing valve circuit to stay closed.
.. Super Setting - Contacts 21-24 close.
The normally closed overflow switch has
been placed in the fill circuit for safety
reasons. If an overflow condition arises,
the switch will open which also opens the
fill circuit and shuts off the water.
Water Level Switch (Rear View)
The water level switch can be accessed
as previously detailed under
Control
Panel Disassembly.
WATER LEVEL SWITCH TESTING:
The water level switch can be tested
using an ohmmeter and executing the
following:
" Overflow terminals 31-32
should
always
indicate continuity.
.. When the tub is empty, ohmmeter
leads placed across terminals 11-14
should not
indicate continuity.
" When the tub is filled, as per the switch
setting
Low, Medium, or High,
contacts
11-14 should indicate continuity, but
contacts 21-24 should not. When the
tub is filled to the
Super
setting, contacts
11-14 and contacts 21-24 should
indicate continuity.
