Nortec Industries MES-U manual Water remains at high level and won’t concentrate

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.
