PROBLEM

Spitting or excessive steaming

PROBABLE CAUSE

1. Lime Build-up

CAUTION - Tank and tank compo- nents should be delimed regularly depending on local water condi- tions. Excessive mineral build-up on stainless steel surfaces can ini- tiate corrosive reactions resulting in serious leaks.

REMEDY

Inspect tank assembly for excessive lime deposits. Delime as required.

2. Control Thermostat
