WATER QUALITY
(Continued)
2. The water level probes become coated with scale. Scale will bridge across the probe
insulator from the metal extension which senses the water level in the boiler shell. Once
this scale becomes wet, the water level control is unable to maintain the proper water level
in the boiler. This situation may cause an electric heating element to fail if the element is
not adequately covered by water.
Strainers and filters will not remove minerals from the water.
Refer to REMOVAL OF LIME SCALE DEPOSITS, page 19.
