Red “Change Cylinder” light on - Water NOT at top of
cylinder:
Water foaming to top of cylinder causing false full
cylinder indication. This also may be accompanied by
arcing (flashing) inside cylinder. Refer to “Terms
Used” regarding foaming.
Water remains at high level and won’t concentrate:
This is normal on cold start-up and can be
accelerated by adding maximum 1/2 tsp. of dissolved
salt to the cylinder (through the plastic fill cup) on fill
cycle. See “Low Water Conductivity” section of this
manual.
If unit has been operating extensively, observe for
normal fill-boil-fill-boil cycle; no drain should be
occurring. If drain occuring, check for leaking drain
valve or back pressure.
Water beyond top of cylinder up into spout:
If the red light is not on and fill is still activated,
jumper across the connection of sensor on basic PC
board. If fill remains on when connection is jumped,
then basic PC board is faulty. If fill shuts off, then
verify primary voltage to cylinder (contactor
energized). If primary voltage is present, the high
water sensor PCB is defective.
Unit drains continually:
May be caused by foaming and/or back pressure,
or leaking drain valve.
Cylinder is almost empty, check for magnetic pull
on drain solenoid indicating miswiring. If no pull, drain
actuator is blocked open; remove, disassemble and
clean.
If drain is occurring through activated drain valve,
valve is miswired or electronics are faulty - consult
factory.
If drain is occurring through the overflow on the fill
cup, this is due to abnormal restriction on the steam
line and back pressure forces water out of the cylinder;
therefore, water cannot concentrate and level must
stay high; review installation of steam line to ensure no
blockages or excessive static pressure in air system.
